Here’s The 5-Day Weather Outlook For T&T [Thursday Until Monday]

According to the Trinidad and Tobago Meteorological Service (TTMS), a well-formed Central North Atlantic high pressure cell, with a relatively straight fetch across the equator side, is expected to provide steady winds with intermittent patches of moisture advection across the Lesser Antilles during this outlook period.

The wave heights are expected to be between 2.5m and 3m with a period of eight (8) or nine (9) seconds. There is some indication that the wave heights are likely to increase to near 3m by Friday (12th December, 2025).
