Regional Conditions
The Eastern Caribbean is experiencing typical early hurricane season weather as the region transitions into the more active months ahead. Temperatures across the islands have ranged from 23°C73°F in mountainous areas to 33°C92°F on exposed coasts, with Saint Thomas recording the week's highest readings. Humidity levels remain elevated at around 81%, a characteristic feature of the season.
Barbados experienced the strongest winds at 46 km/h29 mph, while scattered to broken cloud cover has dominated the skies. Rainfall has been patchy, with Martinique receiving the most precipitation at 66.5 mm2.62 in, while some islands such as Sint Eustatius remained completely dry. Sea conditions have remained moderate, ranging from 1.2 to 2.4 metres4 to 8 feet.
This Week's Outlook
The coming week will be marked by the passage of a tropical wave system currently positioned over the eastern Atlantic. Instability trailing this system, combined with favorable upper-level atmospheric patterns, will generate periods of passing showers across the Eastern Caribbean, particularly early in the week. Easterly winds are expected to range from 17 to 33 km/h10 to 21 mph, with gusts potentially reaching 52 km/h32 mph over open waters.
As the Atlantic high-pressure system rebuilds across the region, conditions will gradually improve toward midweek and beyond. A broader subtropical ridge will establish itself north of the islands, reinforcing trade winds and moderate to rough seas across the basin. Seas south of 20°N20°N may build to around 4 metres13 feet later in the week as fresh to strong easterly winds dominate.
By week's end, conditions should stabilize with lighter winds and calmer seas across most of the island chain.
Tropical Activity
The National Hurricane Center is currently tracking three tropical waves across the Atlantic basin, though none pose an immediate threat to the Eastern Caribbean region. An eastern Atlantic tropical wave situated along 33 degrees west continues moving westward at 28 to 37 km/h15 to 20 kt, with scattered showers and isolated thunderstorms observed between 30 and 40 degrees west. A central Atlantic tropical wave located along 46 degrees west shows no significant convection at this time.
Closest to the region is an eastern Caribbean tropical wave axis along 69 degrees west, also moving westward at approximately 28 km/h15 kt, with minimal associated convection. The broader Atlantic basin remains characterized by moderate to fresh trade winds and moderate seas across most areas, with a broad ridge of high pressure centered near 1026 mb1026 mb dominating upper-level patterns. Conditions overall remain favorable for a quiet start to this active season.

Residents and visitors should monitor conditions as the week progresses, particularly if travel or outdoor activities are planned. While the tropical wave system poses no hurricane threat, the associated shower activity and wind gusts warrant routine weather awareness.
