A wetter-than-usual dry season is expected for 2025.
The TT Meteorological Service (TTMS) gave their predictions for the season at the 2025 Dry Season Seventeenth National Climate Outlook Forum at the Civil Aviation Authority on December 18.
A presentation from the TTMS at the forum said the dry season accumulated rainfall total for January to May 2025 is likely to be the highest in northern and eastern areas of Valencia, North Oropouche, Sangre Grande in Trinidad and Charlotteville, Speyside, Roxborough and Glamorgan in Tobago.
Rainfall totals could range between 512mm and 766mm.
The country is likely to get 98 dry days (of less than 1.0mm rainfall) during the season, just below the average of 107 days.
