The Climate

    The following chart is an analysis of the climate while we'll be travelling. The numbers after every country show the average number of days of rainfall for each month. (We'll be starting on September 30th.) Note also that the duration is only six months. The extra two months are reserved for travelling north through Central America.

    This is somewhat simplified, as the climate differs widely for some countries. I've tried to reflect that in the description which follows each country.

      The problem here is in Amazonia. While Rio and Brasilia have fairly conistent rain patterns, there is considerably more rain in March than October.

Based on this analysis, I've decided to take the clockwise route around South America. There are two advantages to this...

  1. We can spend time in Colombia in March, when it will be much drier. The heavy rains in Colombia are in October and November as well as April and May.

  2. The clockwise route allows us to travel through Brazil during the dry(er) season. The best time to visit Brazil is August to October (and April to June).
