Zanzibar weather in January at a glance
January is one of the hottest, brightest months in Zanzibar. It sits in the short
dry season between the November rains and the long rains of March, so most days
deliver strong sunshine, warm seas, and only the occasional short shower.
Temperature and humidity
Daytime highs hover around 32°C (90°F), cooling to a warm 24°C (75°F) overnight.
Humidity is high, which makes the heat feel stronger, so plan active sightseeing
and Stone Town walks for the cooler morning hours and save the afternoons for the
beach or the shade of a palm.
Sea and rainfall
The Indian Ocean is bath-warm at roughly 29°C (84°F), inviting for swimming,
snorkelling, and diving. Rain does fall in January, usually as brief, heavy bursts
that clear quickly rather than all-day grey. Visibility for divers is generally
good between showers.
Should you visit in January?
If you want guaranteed warmth and long beach days over the European winter,
January is an excellent choice. It is busy and prices stay high through the early
month after New Year, then ease slightly. Pack light, breathable clothing, strong
sun protection, and a light rain layer for the occasional downpour.
