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 limits

How these numbers are made (what the highs, lows and rain days mean, the sources and the model cell used for Kinshasa) is explained once on the Kinshasa year overview and on the Sources, method and limits page.

Brazzaville 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.
