Montego Bay (Jamaica) weather by month

Montego Bay's forum calls January dry season and generally excellent, sunny with low-to-mid 80s°F daytime highs and low humidity. Regulars flag later January as when what locals call the 'Christmas Breeze' can bring cooler temperatures, higher seas and wind down from cold fronts further north — a light sweater is worth having for the water or the evening.

February in Montego Bay is the middle of the dry season and the forum's account is consistent: hot, sunny for most of the day, and rain that arrives as a quick shower and then clears rather than as a wet day. Our own row carries that pattern - 13.2 precipitation days with only 42.8mm between them. Two things regulars get asked and answer the same way. The sea is a touch cooler through December to February, bracing for a minute and fine after that, and usually warmer than the resort pools in winter. And the evening sweater is mostly unnecessary outdoors; what it is actually for is the air conditioning indoors and restaurant dress codes. The record: 31C days that feel like 33C, 22.3C nights, 10.7 hours of sun, a 27.2C sea and a 19 kph breeze.

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.

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.

Forum posters describe July and August as the hottest months, with average highs around 90F and lows in the low-70sF. Posters consistently frame July as one of the better summer picks for avoiding the heaviest rain - real rainfall totals here do run somewhat lower in July than in the wetter late-spring-through-fall stretch (May through October), even though frequent brief showers remain part of the picture rather than a truly dry month. One visitor reported just a single full day of rain across their entire July stay, with typical showers arriving late afternoon or early evening and clearing within about 15 minutes. Hurricane season runs June through November, but posters note July carries meaningfully lower hurricane risk than the August-September peak.

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.

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.
