Everything below is collected in one spot so you do not have to cross-check Koumassi climate: monthly averages by hand. The gap between Aug and Feb is 3.5 C here: 24.4 C against 27.9 C. Precipitation peaks in Jun (8.68 mm/day) and bottoms out in Jan (0.84 mm/day), so a 10.3x difference between the two. Taken together that is roughly 1,422 mm of rain a year for the grid cell. The same build that regenerates the sitemap refreshes these values, and unchanged pages are left untouched. The table underneath carries the per-month breakdown; the related pages cover the same dataset nearby.

What the Koumassi climate table shows
Values are multi-decadal climatological averages for the 5.29716, -3.96753 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
How much rain is 8.68 mm/day in a month?
Rain is recorded as a daily mean, so 8.68 mm/day is roughly 264 mm across a 30-day month.
