Port of Spain sits firmly in the wet tropical zone, delivering consistent warmth year-round with temperatures hovering between 23°C and 31°C.
The wet season brings heavy afternoon downpours that drench the city with remarkable punctuality, making waterproof gear a non-negotiable part of your wardrobe.
Temperatures rarely surprise, but the humidity certainly will—it hovers around 80% most of the year, turning any brisk walk into a cardiovascular event.
The northeast trade winds provide some relief during the dry months, though calling it 'relief' is generous when you're still sweating through your shirt by 10 a.m.
Light-colored, loose-fitting clothing is the unofficial uniform here, as dark fabrics become sweat-display boards within minutes of stepping outside.
Port of Spain operates on a two-season system—wet and dry—so visitors anticipating autumn sweaters and spring jackets should leave them at home.
