Port of Spain, the capital of Trinidad and Tobago, sits on the northwestern coast of Trinidad on the Gulf of Paria, backed by the steep Northern Range at approximately 10.65°N, 61.51°W. It has a tropical climate (Köppen Aw) — hot and humid year-round, cooled by trade winds — with a wet season and a dry season, and it lies south of the hurricane belt.
There is no summer in the temperate sense: temperatures stay hot and steady, with daytime highs around 31–32°C and warm, humid nights near 22–23°C, tempered by the trade winds. The wet season, from June to December, brings heavy afternoon downpours and thunderstorms, with a short drier break — the petit carême — around September.
There is no true winter, but the dry season from January to May brings sunnier, breezier days with much less rain and slightly lower humidity, cooled by the northeast trade winds. Temperatures barely change; this bright, dry stretch coincides with Carnival and is comfortably the best time of year.
Port of Spain receives on the order of 1,600–1,800 mm of rain a year, concentrated in the wet season from June to December, while February to April is markedly dry; the Northern Range behind the city receives considerably more. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.
Trinidad lies far enough south to sit largely below the Atlantic hurricane belt, so direct strikes are rare — a significant advantage over the islands to the north. Its wet season instead brings a distinctive short dry break in September, the petit carême, when the rains briefly pause before resuming.
