Regional Conditions This Past Week

The Eastern Caribbean entered a transition period over the past seven days, with conditions reflecting the shift between seasons. Temperatures fluctuated across the archipelago, ranging from a cool 22°C72°F in the northern islands to a warm 32°C90°F in the south. Grenada recorded the week's highest temperatures, while variable cloud cover dominated the region.

Moisture-laden trade winds brought rainfall to several islands, with Dominica receiving the most significant accumulation at 67.2 mm2.65 in, while Sint Eustatius remained exceptionally dry with only 0.3 mm0.01 in. Peak winds reached 45 km/h28 mph in the southern islands. Atmospheric pressure held steady at an average of 1017 mb, with relative humidity maintaining elevated levels around 80% across the region.

No tropical systems developed in the Atlantic basin during this period.

This Week's Outlook

The coming week will maintain the unsettled pattern established over the past few days. Pockets of low-level moisture will continue moving through the region on a moderate to fresh wind flow from the east. A weak upper-level trough positioned across the area will enhance atmospheric lift, combining with the moisture to produce partly cloudy to cloudy skies.

Residents and visitors should anticipate periodic showers and brief periods of rain, though conditions will remain typical for the transition season rather than extreme. Winds will blow from the east at 11 to 30 km/h7 to 18 mph, creating moderate sea conditions. Marine forecasts indicate sea heights between 1.2 to 2.4 metres4 to 8 feet, suitable for most maritime activities with appropriate caution.

Temperature trends should remain relatively consistent with recent observations, though showers may produce localized cooling. No tropical threat is anticipated.

Looking Ahead

This transition period reflects typical late-May weather patterns for the Eastern Caribbean, with neither the dry season's stability nor the hurricane season's organized systems currently influencing regional conditions. The weak upper trough and moisture influx will gradually shift as the week progresses, though unsettled conditions should persist through the period.
