Week Weather Forecast: Mostly Hot, Sunny Conditions

Weather Forecast For This Week

This week, the general pattern will remain the same. A surface to mid-level high pressure system will continue to dominate conditions across the Eastern Caribbean. Surface to low-level convergence, on the southwestern periphery of the ridge (high pressure), will aid in the development of occasional cloudiness.

There will also be a low chance of showers, particularly during the early morning across both islands. There is also a low chance of brief, light to moderate showers occurring later in the afternoons of this week, predominantly across western areas of Southern and Central Trinidad.

Very little rainfall accumulations are forecast this week, with trace accumulations across both Trinidad and Tobago in the event of an isolated shower. Eastern Trinidad may see up to 5 millimeters, per day as the meteorological drought persists.

Winds are forecast to be gentle, generally less than 30 KM/H, with gusts up to 50 KM/H at times.


Minimum low temperatures across Trinidad throughout the week are forecast to range between 22°C-23°C. Low temperatures are likely to be lower across inland and mountainous areas. Across Tobago, on the other hand, low temperatures are forecast to be slightly warmer, at 24°C-25°C.

Maximum high temperatures across Trinidad throughout the week are forecast to generally remain hot, near 32°C. Across Tobago, on the other hand, maximum high temperatures are forecast to be slightly cooler, at 29°C-30°C.

The maximum high heat index, or “feel’s like” temperature is forecast to generally remain near a hot 36°C during the early to mid-afternoons of Trinidad and 33°C in Tobago.


Seas are forecast to remain moderate in open waters through the week. Waves in open waters are forecast to remain up to 2.0 meters. Seas in the open waters are forecast to become slight by the latter part of the week, with waves up to 1.5 meters. In sheltered areas, seas are forecast to remain smooth, below 1.0 meters.

Winds are forecast to be from the east, at 15 to 20 knots through Wednesday. By Thursday, winds are forecast to decrease to 10-15 knots, from the East to Southeast.

Saharan Dust (Or Lack of!)

Dust concentrations are now at minimal levels across the Southern and Eastern Caribbean. A mild increase of dust occurred over the weekend, but did not severely reduce air quality levels, as it generally has remained at moderate levels.

Air quality is forecast to remain at moderate levels throughout the week, occasionally lowering to “good” levels.

EPA Air Quality Index Risk Levels

At moderate air quality levels, unusually sensitive groups should consider reducing prolonged or heavy exertion.

Thankfully, long range dust models aren’t indicating any major intrusions of Saharan Dust over the next 10 days!
