The capital and most populous city in Jamaica is classified as a tropical climate characterized by a hot, wet season, and a relatively dry winter season. Trade winds that humidify the northern shores of Jamaica get trapped by the Blue Mountains to the north of the city, creating a rain shadow that keeps Kingston drier than most of the rest of the country. Still, precipitation can be quite heavy during the wet season, and hurricane-type winds can occur.
Throughout the year, air temperatures in Kingston stay constant between 21°C and 31°C. Water temperatures along the shoreline are also predictable, floating between 27°C and 29°C year round.
Like most of the Caribbean, the primary difference in weather throughout the year is the rainfall accumulation. During the dry season (December to April), Kingston rarely sees more than 35mm per month. In fact, January and February rarely see even 20mm of precipitation.
During the wet season (May to November), monthly totals are much less predictable. The rainiest months by far are September and October, which see well over 120mm each.
Kingston is prone to hurricanes. The most impactful ones tend to appear in late August through October, but the city sometimes sees them as early as June or July, as in 2021 when Hurricane Elsa caused mass flooding.
