Everything below is collected in one spot so you do not have to cross-check Mombasa climate: monthly averages by hand. The gap between Jul and Feb is 4.5 C here: 23.9 C against 28.4 C. Precipitation peaks in May (7.00 mm/day) and bottoms out in Feb (0.52 mm/day), so a 13.5x difference between the two. Taken together that is roughly 889 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 Mombasa climate table shows
Values are multi-decadal climatological averages for the -4.0547, 39.6636 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 7.00 mm/day in a month?
Rain is recorded as a daily mean, so 7.00 mm/day is roughly 213 mm across a 30-day month.
