I did the Southern Tier, west to east and had a few days of wondrous tailwinds and a couple of days of really annoying headwinds. Articles I've read over the years say that for a cross the US ride there are no certain prevailing winds, one writer even went so far as to record the winds each day and then graphically display the entire journey's winds on a star graph. There was no clear prevailing wind direction. People who fly coast to coast will always suggest that it's faster west to east, and if I can ever pedal my Surly LHT to 30,000 feet I'll likely agree with them. But, for those of us that pedal on the ground, I don't think there is a better travel direction based on the wind direction.
