This Week's Regional Conditions

The Eastern Caribbean is experiencing a transition period marked by the influence of a tropical wave system. Over the past seven days, temperatures have ranged from 22°C71°F in the higher elevations to 32°C89°F across lower coastal areas. While most of the region has remained relatively dry, some islands have experienced notable rainfall, with Dominica recording 68.5 mm2.7 in over the week.

Atmospheric pressure has held steady at around 1016 mb, and humidity levels have averaged 82% across the region. Wind speeds have been generally moderate, though Barbados and nearby islands experienced gusts reaching 46 km/h29 mph. Cloud cover has varied from scattered to broken throughout the week, creating a mix of partly clear and overcast skies.

This Week's Outlook

The tropical wave system responsible for recent conditions is expected to maintain unsettled weather patterns across much of the region through the coming days. Trinidad, the Leeward Islands, and the northern Windward Islands face the highest likelihood of showers and thunderstorm activity, with periods of significant cloud cover and possible gusty wind conditions. Barbados and surrounding islands south of the primary wave track will experience a more moderate chance of showers with partly cloudy skies, though the threat of thunderstorms remains present.

East-southeasterly winds will continue to dominate the flow pattern, with satellite imagery and live radar showing the slow eastward progression of moisture-laden air. Sea conditions are expected to remain choppy to rough, with wave heights ranging from 1.2 to 2.7 metres4 to 9 feet, particularly across the northern and central portions of the Eastern Caribbean. No active tropical systems are present in the Atlantic basin at this time, and current weather patterns suggest typical late May conditions rather than any organized severe weather threat.

Planning Ahead

Residents and visitors should remain prepared for afternoon and evening showers throughout the week, particularly in areas north of Barbados. Gusty wind conditions may occasionally disrupt outdoor activities and affect marine operations. For detailed island-by-island conditions and the latest updates, visit the weather page.
