Traveller notes on Montego Bay in May
Notes from nearby Negril (51 km away)
Montego Bay doesn't have its own notes for May yet — these are about Negril, close enough to share the season.
Negril-forum threads on May weather call it the start of the warmer half of the year - hot, sunny days punctuated by a brief shower most afternoons, typically arriving around the early-to-mid-afternoon window and clearing again within about ten minutes, sun back out shortly after. May and June together run wetter by the numbers than April, and posters put the odds of rain on any given day at roughly a third, a noticeable few inches accumulating across a two-week stay. The humidity is what regulars flag as the real difference from the cooler months, since the temperature swings only modestly through the year - it's the mugginess that makes May feel meaningfully warmer than a winter visit despite a similar thermometer reading. The record: 29.9C days feeling like a sticky 35C, 25.7C nights, 88mm across 17.2 days, 76 percent humidity, an 11.4-hour sun day and a 29.4C sea.
Other months in Montego Bay
Regulars are specific this counts among the driest windows of the year here relative to what follows, December through April historically the lower-rain stretch, though real showers remain common even in the better months, one visitor reporting rain lasting only about 30 minutes during their entire stay. Our row backs that hot, genuinely wet read, 32.3C reading as a scorching 37C, over 23.7C nights feeling 28C, with a substantial 121.3mm of rain across 19.1 days and humidity at 80 percent. Regulars are consistent low humidity and warm sunny days are the more common experience overall, brief showers rarely disrupting a full day of beach time. This remains one of the recommended windows to visit, spanning November through April by local consensus. The sea sits at a bath-warm 28.1C. The record: 11.6 hours of sun, a 15.5 kph wind and AQI 41.
Montego Bay-forum threads on September weather are direct about the odds: better than half the days in the month bring some rain, and muggy conditions are described as close to constant regardless of whether it's actively raining. The one consistent silver lining - rain here normally arrives as a short, heavy shower rather than a persistent drizzle, sun typically back out not long after. Posters who've stayed a week or more report getting only two or three genuinely rainy days out of the whole trip. Early September marks the peak of hurricane season, and while regulars call a direct hit statistically unlikely, several note it's still worth checking the tropical outlook and having travel insurance in place. The record: a scorching 33.9C by day feeling like a punishing 40C, 25C nights, a notably high 185mm across 26.2 days, 83 percent humidity, a 30.9C sea and 10.7 hours of sun.
Montego Bay-forum threads on March weather call it, along with February, the island's best month - high season, and resorts price accordingly. Showers are consistently described as short-lived when they happen: heavy but quick, feeling refreshing rather than ruining, usually followed by sunshine, with overcast stretches called genuinely rare. Experiences still vary a lot, though - one poster reports ten straight days of perfect sun with zero precipitation in late March, another describes close to the opposite, both from the same time of year. The record leans toward the wetter half of that range: 31.7C days feeling like a sticky 35C, 22.7C nights, 70mm across 16.1 days, a 27.3C sea, 79 percent humidity and 11.1 hours of sun - genuinely warm and genuinely showery, in short bursts rather than washed-out days.
December opens Jamaica's high season and regulars say the season exists for a reason: this is some of the best weather of the year, with the driest stretch running December to March. Our row's 13 precipitation days look alarming until you read the 43.6mm they carry and the forum's description of how it falls - hard and fast along the coast, then breaking for the day into bright sun. Reports range from a single hour-long afternoon shower to nothing at all across a week, with two days of rain from a tropical storm as the worst anyone offers; storms and hurricanes in December they call extremely unlikely. Middays are still properly hot. The record: 31.3C days that feel like 35C, 23.4C nights, 9.8 hours of sun and a 28.7C sea.
