Nights average 23.2°C; one night in ten drops to 22.1°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest April day here reached 33.8°C (1999-04-17) and the coldest night 20.3°C (2019-04-20).
Rain in April
Wet (more than 8 rainy days): about 17 days with 1 mm or more, 90 mm in total. Year to year it varies a lot - the wettest April was 2012 with 187 mm, the driest 1995 with 20 mm. Humidity averages 80%, which makes the heat feel heavier than the thermometer suggests.
Sea temperature in April
The sea averages 27.4°C - warm enough to swim (22°c+). Depending on the year it ranges from 27.1°C to 27.7°C. For the warmest sea here, come in September (29.6°C).
Sunshine and daylight
Around 7.5 hours of sunshine a day (estimated from cloud cover), 12.4 hours of daylight: the sun rises about 05:55 and sets about 18:29 local time in mid-April. Average cloud cover is 39%.
Is April a good time to visit Montego Bay?
It is a reasonable choice: hot days but expect showers. The best months for Montego Bay on our scoring are February, January, March; months averaging 25°C or more: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.
Proper heat, with little cooling after dark
Expect heat to shape your day rather than simply make it more pleasant. Humidity averages 80%, so loose, breathable clothing and somewhere cool to retreat will matter, especially around midday. Days reach 30°C around 45% of the time, making this a poor choice if you prefer mild conditions for long walks. London’s average April high is 13.5°C, so give yourself time to adjust rather than planning a packed arrival day. Evenings remain warm enough for lightweight clothes, and air conditioning is a sensible accommodation priority if you struggle to sleep in the heat. Sun protection and regular drinks belong in your daily routine.
Plenty of sunshine, but plan around wet weather
April brings about 16 rainy days, so rain is a realistic part of the holiday rather than an outside possibility. There is still about 7.5 hours of sunshine within 12.4 hours of daylight, leaving scope for time outdoors without promising uninterrupted clear skies. Pack a light waterproof and keep plans movable rather than tying every day to dry weather. The figures do not tell you when rain will arrive or how long each spell will last, so do not assume it will always be a brief afternoon shower. April suits travellers who can accept wet interruptions in return for reliable heat and warm sea temperatures.
