Temperature in Zanzibar in October

The narrow 5°C gap between daytime and overnight temperatures, characteristic of coastal cities with maritime moderation, means a single mid-layer works across the whole day. At 82% humidity, the 29°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. UV index averages 6 this month, classed as moderate. Sunscreen is a sensible precaution for extended outdoor time, particularly at midday. Wind averages 18 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 84°F average high, 75°F overnight low.

Packing for Zanzibar in October means dressing for 29°C days and 24°C evenings. A lightweight linen or cotton shirt with loose-fit trousers or a sundress handles the 29°C daytime heat. Evening temperatures settle at 24°C, a modest 5°C drop that a light cardigan or denim jacket covers. For footwear, breathable walking sandals work for casual exploration, but closed-toe trainers are better for uneven surfaces in the historic centre. A compact foldable umbrella weighs almost nothing and earns its keep across 11 potential rainy days. At 82% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.

💡

Local tip: Layers are more practical than a single heavy garment in Zanzibar. The day-to-evening temperature shift rewards packing a versatile mid-layer you can add or remove as conditions change.

Events in Zanzibar in October

Why is Zanzibar warm in October?

Climate data: Open-Meteo ERA5 (1991–2020).

The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.

A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate -- wear sunscreen. UV 6-7: High -- hat and SPF 30+ essential. UV 8-10: Very High -- limit midday exposure. UV 11+: Extreme -- seek shade between 10am-4pm.
