When to Ride: Southern Tier

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

How long it took you both? What was your average distance per day?

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.

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've been thinking about riding this route starting sometime in December and finishing sometime in January. Does anyone know what the conditions are that time of year?

Southern Tier-thinking of leaving eastbound from San Diego to St Augustine on Nov 10 Any advice about leaving that time? Ive researched temp averages and it looks ok all the way across with temps mainly in the mid 60s. Any thoughts on this time frame would be appreciated. Andy

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!
