Read the numbers correctly
Climate, not a promise.
These patterns help compare months. They cannot tell you the weather on a specific day of your trip.
Sources, method and limitsHow these numbers are made (what the highs, lows and rain days mean, the sources and the model cell used for Brazzaville) is explained once on the Brazzaville year overview and on the Sources, method and limits page.
Kinshasa lies in the same rainfall cell, so its rainfall figures are identical to these; temperatures come from the same 0.1° cell and differ only by the elevation adjustment.
