Weather in Mombasa in July
Kenya · 20-year averages, July
A good month. July is a solid month to be in Mombasa. Highs average 29.7 °C, lows 21.8 °C, and rain falls on 8 days — nothing in the month is working against you.
July is the highest-scoring month of the twelve. The nearest rival is August, and the month at the other end of the year is November.
Rain on 8 days, 0 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 29.7 °C days and 21.8 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: 13 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest July day reached 32.5 °C and the coldest night fell to 17.4 °C.
July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 75 mm against 5 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 36 mm average is a reasonable planning figure, not a promise.
Wind is light at 15.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, high enough to notice on the warm days without dominating them.
How July sits in the year
Temperatures hold steady either side: 29.7 °C in June, 29.7 here, 30.6 in August. Nothing about the timing within the month matters much. Rain has already shifted: 5 days fewer than June had.
Daylight in July
Mombasa sits close enough to the equator that daylight barely moves all year — 11.9 hours in July, against a range of just 0.5 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
Sea temperature
The sea sits at about 26 °C in July — warm enough to stay in as long as you like. The sea peaks at 29.4 °C in April and bottoms out at 25.7 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
July in Mombasa versus nearby
If Mombasa is one option among several, the nearby comparison is worth making. Zanzibar is a better bet in July — 2.7 °C cooler, 4 days less rain. Dar es Salaam is a better bet in July — 2 °C cooler, 5 days less rain.
So: July is the answer for Mombasa. If it is booked out or priced out, August is the next best thing at 4 points behind, and November is the month to keep off the shortlist.
