For a UK traveller, that means a clear change from March at home, with light clothing, flexible outdoor plans and some care over heat rather than a completely rain-free holiday.

Between 1991 and 2020 the hottest March day here reached 33.5°C (2005-03-24) and the coldest night 17.8°C (2018-03-07).
Rain in March
Wet (more than 8 rainy days): about 12 days with 1 mm or more, 55 mm in total. Year to year it varies a lot - the wettest March was 1998 with 141 mm, the driest 2005 with 16 mm. Humidity averages 78%, which makes the heat feel heavier than the thermometer suggests.

Sunshine and daylight
Around 7.7 hours of sunshine a day (estimated from cloud cover), 11.9 hours of daylight: the sun rises about 06:20 and sets about 18:21 local time in mid-March. Average cloud cover is 35%.
Is March 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.
Hot days and warm evenings
Expect proper hot-weather conditions rather than gentle spring warmth. The average daytime high is 28.9°C, and 23% of days reach 30°C, so plan anything energetic for earlier or later in the day rather than midday. Humidity averages 78%, which can make the heat feel more demanding, especially while you are adjusting after arriving from the UK. Loose, breathable clothes, shade and regular drinks are sensible priorities. Nights average 22.4°C, so evenings usually call for light clothing rather than a heavy layer. March suits travellers who enjoy warmth throughout the day and evening; it is less suitable if you prefer cool conditions for walking or sleeping.
Plenty of sunshine, with rain to plan around
March brings about 7.7 hours of sunshine within 11.9 hours of daylight, leaving plenty of scope for swimming and time outdoors. The catch is rain on about 12 days: do not treat this as a reliably dry month. That figure does not mean those days are wet throughout, but it is a reason to keep plans flexible rather than depend on uninterrupted sunshine. Carry a light waterproof and keep something to do under cover in mind. March sits alongside February and January among Montego Bay's best months overall, so it is a reasonable choice if you accept that good holiday weather here can still include rain.
