I will be travelling from December 2014 till the end of May/mid June 2015. I'd like to do a motorcycle trip through the Americas. Originally the goal was South America, but I plan to buy the bike in the States and go from there. Anyway, I'm trying to work out an easy way to understand what the weather is going to be like over such a vast area so I can plan my route.
Has anyone worked out an easy way to understand what the weather is like?
