Port of Spain weather in May

Regulars date the rainy season here from June, which makes May the last of the dry half and a common worry for people booking mid-month. Their description of what follows is the useful part: squalls of twenty or thirty minutes with sun behind them, cloud building through the day and rain in the afternoon, rather than a northern kind of wet day. Our May still reads dry in total, 59.2mm, though it falls across 12.8 days. Heat is the constant at 31.4C reading as 34C over 25.3C nights, with a 27.9C sea and a 30.9 kph trade wind. Rough water later in the year cancels boat trips; in May it mostly just cools the beach. The record: 11.4 hours of sun and AQI 53.

Detailed July-specific trip reports for Port of Spain are relatively thin on the forum, with more discussion focused on rainy-season logistics generally than granular July detail. Posters discussing the broader Trinidad and Tobago rainy season, which runs roughly June through December, describe frequent, often heavy but typically short-lived downpours rather than sustained all-day rain, consistent with the wet-season pattern across this part of the southern Caribbean. Given the limited destination-specific detail for this exact month, this note leans on that broader seasonal cue: July sits within the wetter half of the year for Port of Spain, with hot, humid conditions and a real, near-daily chance of rain that visitors should plan flexible outdoor time around.

Forum coverage of Port of Spain's January weather specifically is thin, with one poster's thread title itself suggesting rain is a real enough possibility to plan a visit around potentially rainy days. Given the limited detailed trip reports available, the broader Caribbean January pattern - the drier, cooler half of the year across most of the region - is the most useful general guide, though Trinidad's position further south and closer to the South American coast means its climate runs a bit more humid and rain-prone year-round than islands further north in the Caribbean chain. Posters generally recommend having backup indoor plans in case a January day in Port of Spain does turn rainy.
