Here’s The 5-Day Weather Outlook For T&T [Wednesday Until Sunday]
A surface perturbation following the Wave continues the increased convergence and moisture build-up across the Eastern Caribbean on Thursday (30th October, 2025).
A trough, presently located near 35W, is indicating a spot of moderate vorticity within the Inter-Tropical Convergence Zone (ITCZ). As this trough moves generally Westward at this time, there is likely to be a Northward modulation upon nearing the Lesser Antilles, which is expected to bring increased moisture build-up and convective weather across the island chain on Friday (31st October, 2025).
Looking Beyond This Outlook Period
- At this time, looking ahead in the Area of Interest during the seven (7) days following this outlook period, there are no significant features analyzed, except for intermittent equatorial convergence and associated moisture advection.
- These early analyses so far into the future are subject to much variation as time progresses. The Met Office said it will continue to analyze and monitor all developments, or possible developments, within our Area of Interest.
Seas
- The wind waves in the open waters to the near-East and Northeast of Trinidad and Tobago are expected to be initially near 2m, eventually rising to above 2.5m by late Saturday (1st), and peaking near 2.8m on Sunday (2nd), during this outlook period.
Wind
- The wind in the near-surface to the lower mid-level over Trinidad and Tobago and the Southern Windward Islands (2,000 ft to 5,000 ft) is expected to be initially near 10 kts to 15 kts, but increasing to 20 kts to 25 kts on Saturday (1st) and further to 25 kts to 30 kts on Sunday (2nd). Direction is expected to be between East and Southeast for this outlook period.
Dust
- Mostly mild to moderate concentrations of Saharan dust will be present in the atmosphere at first, but increasing to moderate to high by Saturday evening (1st).
- Sensitive persons are advised to take the necessary precautions.
Synopsis And 5-Day Outlook
