Best time to visit Mwanza
Tanzania · 20-year averages
July is the best month in Mwanza, scoring 85 out of 100, with October the weakest at 54. The 31-point spread means timing is worth planning around without being decisive. The good window runs June to July — 2 months within ten points of the best.
September is the warmest month at 30 °C and December the coolest at 26.5 °C — a 3.5 °C spread across the year. Around 98 days a year top 30 °C, concentrated in September and the months either side.
There is a real wet season here. March, April, November and December carry the rain — up to 26 wet days in a month — while June to August drop as low as 3. That 23-day gap is the biggest single difference between a good month and a bad one in Mwanza, and it moves further than the temperature does.
Daylight barely moves: about 12.3 hours whatever the month, which removes one variable from the decision entirely.
The three strongest months are July, June, August. The one to think twice about is October. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
