Regional Conditions This Past Week

The Eastern Caribbean experienced typical transition season weather over the past seven days, with temperatures ranging from 21°C70°F to 32°C90°F across the region. The warmest readings occurred in the northern and central islands, while cooler overnight temperatures marked the southern reaches. Moisture patterns remained variable, with some islands receiving light rainfall while others stayed largely dry.

Wind speeds generally remained moderate, with gusts reaching 41 km/h25 mph in exposed areas. Sea conditions reflected the moderate wind flow, with swells building during the latter part of the week.

This Week's Outlook

The coming days will be marked by the influence of an upper level trough moving through the region, combined with pockets of low level moisture advancing on a moderate to fresh east-northeasterly flow. This combination creates a heightened chance of showers developing periodically across the islands from the British Virgin Islands southward through Trinidad and Tobago. Some of these showers could intensify to moderate or locally heavy intensity at times, particularly over elevated terrain and during peak afternoon heating hours.

Winds are expected to remain steady from the east-northeast at 19 to 33 km/h12 to 21 mph, with gusts climbing to 48 km/h30 mph mainly over open waters and higher elevation areas. Seas will build to 1.5 to 2.8 metres5 to 9 feet as the week progresses. Atmospheric pressure remains steady near 1015 mb, typical for this season, with no tropical systems developing in the Atlantic basin.

Humidity levels will stay elevated at around 79 percent, contributing to the persistent moisture and cloud cover expected through the period.

Looking Ahead

This is a transitional week between the dry season and the onset of the Atlantic hurricane season. Residents should remain prepared for brief periods of heavier rain and maintain awareness of sea conditions if traveling by boat.
