When to Ride: Southern Tier

September 12, 2013

I've got the Southern Tier Bicycle Route on my mind these days in no small part because we're currently updating two sections of the route.

The Southern Tier is one of those routes that has a distinct "season" for riding due to the effect extreme weather conditions can have on a cyclist's experience. We believe it is generally best ridden early fall or spring for optimum conditions.

There are three factors contributing to this advice: deserts, mountain passes, and hurricane season.

The long desert stretch from Brawley to Palo Verde, California, can produce high temperatures even in early May. As we recently heard from a concerned resident of Palo Verde, "During May, this locale needs to be wisely considered day by day according to the temperature. After late May to mid September, this locale is not at all safe to be out on a bike. We spike up to 130 degrees, average 118 for many many days without cooling at night...well it cools down [at night] to 100 degrees."

Compounding the issue of high temperatures is also the relative lack of services, including sources of water, on this stretch. Many of the businesses — including campgrounds — are run seasonally and close during the summer months due to lack of business.

On the flip side, though the Southern Tier only crosses the Continental Divide three times, the highest pass in New Mexico is over 8,000 feet and late spring or early fall snows closing the passes temporarily is not unusual. Most of the time they are cleared in a day or two with snow accummulation pushed to the side of the road. You will need to pay attention to weather reports and be prepared to wait it out a day or two if need be at these times.

And finally, hurricane season can have a detrimental effect on the route from Baton Rouge, Louisiana, to Pensacola, Florida, and sometimes even as far west as Navasota, Texas. The official hurricane season is typically June through November with the peak considered to be August through October. Even if a hurricane doesn't come inland far enough to impact the route directly, there is a ripple effect on services and traffic volumes as displaced populations and rescue/rebuilding workers move in.

Based on the above factors, for spring eastbound departures, we advise leaving in early March while westbound departures could occur as early as February to be across the desert by the end of April. For fall eastbound and westbound departures, early to mid-September is a good target.

Me and my buddy Matt did west to east in 2011 starting march 20th(flew over from England) and had an awesome trip.Pretty hot for a couple of Brits but got used to it quickly. In 31 days didn't have one drop of rain on us,amazing.All Americans across route treated us like royalty, love them all,so much that I came over and cycled Atlantic coast in march and am planning pacific coast for next year.We ran a very interesting blog,including poetry every day(about our day) which you can find on dmjacrossusa.tumblr.com see you all again soon in the US, happy cycling. P.s.anyone need accommodation when pedalling in GB drop me a line,Dave Atkinson

I rode the Southern Tier west to east, spring of 2008. Was told by many locals all the way as far as Louisiana how unusual the weather had been that year. 40 mph headwinds straight out of the east; 40 plus degrees cooler than normal; torrential downpours; ferries out due to flooding and even a tornado. This was my first long distance bike tour... and I loved every brutal minute of the adventure.

Today, September 15, is the day I would consider the beginning of the tour season for Southern Tier crossing the border of Arizona and California. The early morning hours are in the high 70's and the long desert crossings can be finished by noon if you depart at 4 am. The day time temps are still in the low 100's around noon to 6 pm. The temperature will fluctuate, some days cooler down to upper 90's, and the rainy thunderous monsoons are over. See you in Palo Verde. Host for Southern Tier, Glamis Sand Dune Support.

September 15, 2013, 5:15 PM

Hi Nancy,

I'm planning on starting towards the end of September, or first week of October.

I'm traveling with two dogs and want to wait until the temps are 90 or lower. (The dogs will be in a trailer with cover.)

The sites I've been to show that October averages 89 or below, not sure this reflects the beginning of the month however.

I'll be biking across the country on January 4th with my buddy Taylor. We will be biking the southern tier starting on the east coast. Anyone have any knowledge of weather conditions during the winter? Any pointers for inexperienced bikers like Taylor and I? Any and all comments will be greatly appreciated.

Darren, My friend Jenn and I are doing the Southern Tier leaving San Diego on Jan 1st. Perhaps you and Taylor will pass us, but it would be great to travel together a few days if our schedules allow it. Maybe by the time we are three days into our tour we can give you some pointers, but I don't have any actual experience touring or at this time and place of the country. Good luck, hope to see you on the road!

Georgia, how did your trip go? I am also planning on doing the southern tier, starting in San Diego on January 1st. Did you run into any problems? Recommendations? What was your overall experience like?

October 31, 2014, 2:01 PM

Connie, the trip was life changing! If you're going strictly by the ACA maps, there are a few things to be aware of (though the maps themselves are very good!). The hills on the first three maps of section one were brutal. On section 1, map 6 is Glamis. Try not to get there on the weekend or one day either side as it's full of recreational vehicles and folks having fun but not watching out for cyclists. The store there charges extremely high prices and even $5 per bathroom use. Nancy near Palo Verde was a great cyclists only host! The hostel at Marathon, TX was not sure if they were open to guests or not, and it was quite a search to find a number to reach anyone, but we got to stay a night. The alternative was several hundred dollars for a night at the hotel, out of our budget. There were Warm Showers hosts in town too, we heard later. If you haven't discovered it already, warmshowers.org is a great way to get to know local enthusiasts and have a spot to lay your head without charge. Texas experienced its worst winter on record last year, but everyone was hospitable beyond compare! I would highly recommend tire lining strips as well as thorn resistant tubes and stay off the grass and road shoulders to avoid flats. Used tires get flats many times worse than new. We carried spare tubes, patch kits, chain, tools, and extra rack bolts, etc to do repairs along the road.

Over all, I loved the solitude for hours on end every day and seeing the cultures and people along the way. I learned a lot about myself and healed a lot through this ride, but as the saying goes, no pain, no gain. It was much harder physically than I expected, and I'm used to hard work. It was harder mentally and spiritually as well. If you are riding with a partner, it's very similar to being married, so take (and be!) a good one or expect to not necessarily be good friends after the fact!! Through Florida, the route was more scenic and we were ready to reach St. A so we took several shortcuts via google maps and shaved off over 100 miles. Once we got there, the Pirate Haus Inn and Hostel was an awesome landing place!! Email me if you have any questions I could help you with at girl4god88@gmail.com. If you're looking for a day by day journal of the trip with pictures of terrain, I kept a blog at faithinactionblog.org and the posts should still be there. Good luck on your ride, and enjoy some part of each day as much as possible!

In 2002 I left St Augustine I October, arriving 8 weeks later in early December. Great trip, loved every moment and met some wonderful people. Weather was very mixed: hot and humid in Florida, wet and British part of the time and a few very cold days. My recumbent trike had a sun shade fixed which was a huge benefit on those long hot hills.

Averaged 60 miles a day with a rest day every 8 days or so. Met a number of cyclists going the other way but was very happy going east to west, and the wind was with me as much as it was against me. Also meant I was a bit fitter when I reached the mountains!

Good luck to those of you planning your trips, i am quite envious!

I'm planning to cycle from San Diego toward Navasota starting around March 8th-10 (2015). I wouldn't describe myself without experience but neither really experimented. Would you recommend me to use my full carbon bike with a cargo or an aluminium frame bike? Any advices for me?

All comments will be really appreciated.

Thanks everyone!

hey there Josh and Shoeless Jo. I hope you had a great ride. I am planning to ride the Southern Tier this coming spring. I am going to start in San Diego on February 28,2016. How were the temps? how cold should I plan for at night? I will be camping the whole trip. I have done the Atlantic Coast and the Pacific Coast. both during the summer months. I have a 40degree sleeping bag. Should I invest in a heavier one?

October 8, 2015, 6:28 AM

Did you make the trip as planned. Am going to give it a go in February / March 2017.

Recently retired and caring for my wife of 44 years as a hospice patient. Always loved cycling and was planning on the Southern Tier, self supported to clear my head once nature has run its course with her illness. I was hoping to leave west to east in September of 2015, but I've never attempted something like this and wondered about resources and or guides to help me prepare and seek out the right equipment. Any comments or suggestions would be greatly appreciated.....

March 2, 2015, 12:14 PM

I am thinking about biking the southern route in 2016. I cannot begin until the second week of May however. I am used to the hot weather (I bike through the summer in my home state of Arkansas). Will this late start prove to be a big problem?

March 30, 2015, 11:49 AM
Jennifer Milyko


Either direction it is probably not ideal but carry lots of water and ride early and late versus the middle of the day. I think you'll find the heat across the desert is different than in Arkansas, much drier.

March 30, 2015, 1:55 PM

Dan and Todd, I toured across the Southern Tier in the 80's, left San Diego on June 1st. Hot and difficult in Imperial Valley area headed to Yuma, AZ. I was young, excellent condition, able to knock out 100 mile days with a loaded touring bike. That section I rode a few very early mornings, 3am to about 11am. After Quartzite, heading northeast, temps cooled toward Flagstaff. I hope Dan made his trip. Surly LHT, canti brakes, Tubus racks, Ortleib or Arkel, backpacking stove, some coffee, a few backpacking meals... patience. I might try it again April 2016.

I am looking to bike on the Southern Tier from February 29th to March 25th. I am considering starting at New Orleans heading West and hoping on the Amtrak Train for certain sections of the trip so that I can make it to Palm Springs in this time frame. Does anyone have any experience biking this route with the assistance of the Amtrak? What sections of the Souther Tier are most memorable and best suited for March?

We have some information on using Amtrak in your bicycle travels on our Multi Modal Travel page: https://www.adventurecycling.org/bicycle-tourism/multi-modal-travel/ (be sure to see the spreadsheet of Amtrak accommodations). For more feedback on what to see on this stretch of the Southern Tier at this time, I would suggest making a posting on our Forums in the Routes discussion area: http://forums.adventurecycling.org/index.php

I will be over from London cycling the Southern Tier East to West starting about 1st or 2nd Feb 2016. Always keen to meet other travelers!

January 23, 2016, 2:29 PM

I will be cycling eastbound the Southern tier from San Diego to El Paso starting 1 week of April. I have about 3 weeks for this.

I am think this will be ok for crossing the desert and I am hoping any passes will be free of snow by then?

Any help suggestions are welcome.

thanks Marc

I would guess you will be ok with this timeframe. You'll still see snow and colder temperatures in the mountains but they ought to be passable. Good luck and have fun!

Hey Jimmy. I'll be doing the Southern Tier in 2017. Departing San Diego in March. Exact date TBA as I haven't bought my ticket there yet. This isn't my first trip. I've done Seattle to San Diego twice, Seattle to Green Bay, Cincinatti to Seattle and Portland to Portland. I finished my last ride on August 5 after traveling 5,177 miles from Portland, Oregon to Portland, Maine solo. I'd like company for my 2017 Southern Tier ride.

Hey there everyone! Currently on tour - left from nyc to savannah on the Atlantic coast train Sept 30 - currently just outside of Austin Tx waiting out some nasty rain storms. Looking at the mountain passes I have coming up in New Mexico and worried about snow and cold. Any advice or resource a for making sure it is still passable for us? Thanks so much

Hi Dana,

State DOT websites are often your best resource for finding out the road conditions ahead. Here are some links for your convenience:

NM: http://nmroads.com/mapIndex_2016090801.html?

AZ: https://www.azdot.gov/projects/other-restrictions/road-restrictions

CA: http://www.dot.ca.gov/hq/roadinfo/mtnhwys.htm

And often, if you dial 511 you can get this type of information from recordings. The system will automatically direct you to the information for the state you are currently in.

I hope this helps,

I rode the Florida Connector/Southern Tier solo east to west last year. I left Key West on March 6, a couple of weeks later than originally planned because of another commitment. In retrospect, I wish I had started in mid-February at the latest. Picked east to west because of the Florida temperatures, and for the relative flatness of the terrain (need to build up my riding strength). Between the Connector and the first leg of the Tier, as well as several days off for visiting and weather, I didn't hit Alabama until April 2.

The toughest part of the ride physically was hitting the Hill Country in Texas and getting used to climbing. After that, West Texas was gorgeous in a desolate sort of way. Had more opposing wind in this section.

When I got to Silver City, NM in early May and looked at the desert temps in Arizona and California, we were looking at record highs, somewhere between 105 and 110 with promises of higher as I went west. Too hot for an Ohio boy, so I bagged the rest and headed home. Got 2,850 miles in before I was done.

I met my first east bound riders at St. Augustine and the last at Langtry, Texas, where I met a couple of Swedes. That was April 26, so I figure they had left San Diego 5 or 6 weeks earlier. I didn't meet anyone else the rest of the trip, so I figure the last east bounders must have pulled out no later than early March. I think I met only one other west bound set of riders.

Looking at the maps now for a Northern Tier ride this year. West to east, I think.

I am in the process of planning a slightly modified solo Southern Tier trip, starting from Las Vegas NV, (as I live here) to St. Augustine Florida, which coincidentally is where I grew up. I am planning the Eastbound leg for an early March 2018 departure, and the return Westbound leg, after a few days rest in St. Augustine in Mid April.

I am hoping there are others on the road to spend a few days riding with, especially in the back country areas through the desert. :)

Hi Rick

Am planning a trip around a similar time, what do you know about the weather climate...I cant figure out if I am going to burn or freeze!

Maybe we may get the chance to cycle together :)

November 8, 2017, 2:43 AM
Rick Watkins

Hi Emma,

At the start, you will encounter probably ~ 30F at night, and ~50F during the day, as you head east it will steadily get a little warmer. I am planning for the cold, with the intention of mailing equipment back home as I get further along, and it warms up, and the cold weather gear won't be needed.

NOAA is saying that there is a La Nina pattern forming, and predict a warmer and shorter "winter" than normal, but I'm not a firm believer in LOOOOONG range forecasts.

Overall I'd not fear the heat, during your ride of the ST.

For sure, I'd enjoy the chance to ride together, it's a long road out there. :)

I too am looking for a partner. Like to stay in cheaper Hostels than camping some of the time. But can camp easily too.

I am planning San Diego to St Augustine (Florida) in beginning of March 2018. About same age, I do comfortably 100 k a day, And cycled in Europe (Nice to Geneva this summer and John O'Groats Uk to Lands End 3 years ago.

Interested? Would like to exchange. I am from Canada.

Are you still planning to head off from SD in March? I'm planning to do just a chunk of ST and may be interested in having a buddy out on the road. My ticket isnt bought yet. Im from Ontario.

January 22, 2018, 11:05 AM

I'm planning on doing a section of the route from San Diego heading east starting sometime between Nov 1 - Nov 15 2017. I plan to ride to mid December, however far I get. It will be my first long tour, I'll have done 1 medium tour (330 miles) before then. Let me know if anyone else has a similar schedule!

September 19, 2017, 2:51 PM

I'm starting out from Phoenix December 2017 heading east on the Southern Tier. I rode from Mississippi to Vermont then Vermont to North Dakota on the Northern Tier two years ago. Didn't see many riders and hope to see more this time. I think the temperatures are going to be 60's and 30's. Please let me know if I'm wrong.

How is January or February to bike the Southern Tier from West to East ?

July 23, 2018, 8:22 AM

It will be a bit chilly and potentially wet with a bit of snow in the mountain passes of New Mexico. Also keep in mind the days are shorter so there are fewer hours of daylight to ride.

There is more information on the Southern Tier Route page under the Logistics tab.
