Zanzibar climate: what a normal year looks like

The thermometer moves little from one season to the next: typical afternoon highs range from 28 °C in July to 31 °C in February, and the coolest nights (August) average 22 °C.

Days are almost the same length all year: 11 h 45 min of daylight in late June, 12 h 28 min in late December.

A normal year brings roughly 1,010 mm of rain — more than 50% of the towns of 20,000+ people we compared it with.

The coming week looks normal for October: forecast highs average 30 °C, against a usual 30 °C.
