Temperature in Montego Bay in December
The narrow 4°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 78% humidity, the 27°C daytime high feels 2-4°C warmer in practice: quick-dry fabrics and shade-seeking between noon and 3pm are the sensible response. The UV index of 3 is low, meaning sun exposure is minimal concern and sunscreen is largely optional. Wind averages 18 km/h, light enough to be refreshing on warm days but noticeable in open coastal areas or elevated viewpoints. In Fahrenheit: 81°F average high, 73°F overnight low.

Packing for Montego Bay in December means dressing for 27°C days and 23°C evenings. A light cotton tee with a casual overshirt works well at 27°C, the overshirt doubles as a layer for air-conditioned venues. Evening temperatures settle at 23°C, a modest 4°C drop that a light cardigan or denim jacket covers. Comfortable walking trainers are the versatile choice for both outdoor sightseeing and indoor venues. A compact foldable umbrella weighs almost nothing and earns its keep across 12 potential rainy days. At 78% average humidity, quick-dry synthetic or bamboo fabrics dry overnight and stay comfortable longer than cotton.
