Jamaica's climate is tropical, warm year-round, with a genuine distinction between the dry and wet seasons.
December to April is the dry season and peak tourist period. Temperatures are comfortable (mid-20s Celsius), rainfall is low, and the beaches are at their best. Expect higher prices and more crowded resorts. February and March tend to be the sweetest months — sunny, dry, and not yet baking hot.
May and June are a good shoulder option. Rates start to drop, the island is less crowded, and the weather is still largely dry. Reggae Sumfest draws big crowds to Montego Bay in mid-July.
July to November is the wet season and officially hurricane season (June to November, with peak risk in August and September). Rain usually comes in short afternoon bursts rather than all-day downpours. Prices drop significantly. Jamaica is less exposed to hurricanes than the northern Caribbean islands, but it does get hit — Hurricane Melissa in October 2025 caused significant damage on the western part of the island. Travel in this period carries some risk; travel insurance covering hurricane disruption is strongly recommended.
Inland and mountain areas (the Blue Mountains, Cockpit Country, Mandeville) are noticeably cooler than the coast and receive more rainfall year-round. Pack a layer if you're heading up.
