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. |
