Everything below is collected in one spot so you do not have to cross-check Bamako climate: monthly averages by hand. The gap between Jan and Apr is 8.7 C here: 24.0 C against 32.7 C. Precipitation peaks in Aug (9.55 mm/day) and bottoms out in Dec (0.00 mm/day), so a 2x difference between the two. Taken together that is roughly 1,007 mm of rain a year for the grid cell. Because each page is rebuilt independently, one unavailable upstream never takes the rest of the site down. Exact monthly values are in the table; links below cover adjacent locations and years.

What the Bamako climate table shows
Values are multi-decadal climatological averages for the 12.6091, -7.9752 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
Does Bamako get the same every year?
Close to it. Averaging decades smooths variation, so treat these as typical rather than guaranteed.
