This Week's Regional Conditions

The Eastern Caribbean experienced warm, largely settled weather over the past seven days as the region transitions between seasons. Temperatures ranged from 22°C72°F in the interior highlands to 33°C91°F at lower elevations, with most islands hovering in the comfortable mid-to-upper twenties Celsius. Humidity remained elevated at 82% on average, typical for May conditions in the tropics.

A ridge of high pressure kept skies mostly clear to partly cloudy across the region, with only scattered showers affecting windward areas. Winds remained generally light to moderate, peaking at 41 km/h25 mph in the southern islands. Sea conditions were calm to moderate, ranging from 1 to 2.1 metres3 to 7 feet.

Atmospheric pressure held steady around 1016 mb, reflecting the stable pattern in place. There are no active tropical systems in the Atlantic basin at this time.

This Week's Outlook

The dominant ridge pattern is expected to persist throughout the coming week, maintaining generally settled conditions across the Eastern Caribbean. Partly cloudy skies will be the rule, with only a moderate chance of isolated showers developing, particularly over windward and elevated terrain where moisture is more readily available. Temperatures will remain warm, likely reaching the low-to-mid thirties Celsius in exposed areas and along coasts, with nights cooling to the low twenties as typical for late spring in the region.

Easterly winds will remain light to moderate, ranging from 11 to 33 km/h7 to 21 mph, providing comfortable conditions for outdoor activities and marine operations. Seas will remain manageable at 1 to 2.1 metres3 to 7 feet, ideal for boating and water sports. The absence of any developing systems or significant weather disturbances means this is a reliable period for residents and visitors alike to plan outdoor events and maritime activities with confidence.

Looking Ahead

This week marks a calm and predictable stretch across the Eastern Caribbean, a welcome respite before the region enters the active Atlantic hurricane season in June. Residents should continue monitoring forecasts regularly as conditions can shift, though the current setup favors stability.
