Regional Conditions This Past Week
The Eastern Caribbean has experienced typical transition-season weather over the past seven days, with temperatures ranging from 20°C68°F at the coolest to 30°C87°F at the warmest across the island chain. Shallow low-level moisture patches have drifted across the region, bringing scattered light rain and brief shower activity. Wind conditions have remained relatively moderate overall, though Barbados recorded a peak gust of 52 km/h32 mph during the period.
Rainfall totals varied considerably, with Saint Barthélemy receiving 22.9 mm0.9 in while drier locations like Saint Lucia saw only 3.92 mm0.2 in. Average atmospheric pressure held steady near 1018 mb, and regional humidity averaged 72 percent, typical for this season.
This Week's Outlook
As the week progresses, shallow low-level patches will continue moving across the Eastern Caribbean on a moderate wind flow. Expect partly cloudy to sometimes cloudy skies with a moderate chance of showers throughout the region, particularly affecting the arc from Puerto Rico southward to Trinidad and Tobago. The rain threat remains light in nature, with brief shower bursts rather than sustained rainfall events.
Winds will predominantly blow from the east at 15 to 33 km/h9 to 21 mph, with occasional gusts reaching 54 km/h33 mph in exposed areas. Sea conditions will be moderate, with wave heights of 1.5 to 3.1 metres5 to 10 feet and swells building to 2.1 metres7 feet. Those planning marine activities should account for these conditions, particularly in areas exposed to the Atlantic swell.
The Atlantic basin remains clear of any active tropical systems, keeping the focus on local weather patterns driven by the seasonal transition.
Looking Ahead
This marks a quieter period in the Eastern Caribbean weather calendar, with no significant disturbances on the horizon. Conditions should remain manageable and typical for mid-March, characterized by light to moderate activity and no extreme weather threats.
