72 Hours Outlook

The Atlantic high pressure system has re-established itself, resulting in mainly fair skies and slight haze persisting across the islands. However, model guidance suggests this will be short-lived as low level instability will approach our area by Monday afternoon/evening. Should this forecast hold true, occasionally cloudy skies and light to moderate showers are expected into Tuesday.

Easterly to northeasterly winds of 20 to 35 km/h(12 to 22 mph) will persist before decreasing to 15 to 25 km/h(9 to 16 mph) by Monday. Seas are currently agitated by the winds speeds and should remain moderate to rough in open waters with swells peaking near 1.5m on the western coasts and near 3.0m  on the east coasts. Due to the gradual reduction in swell heights, the Small-Craft and High-Surf Advisory currently in effect for SVG will be discontinued at 6:00 AM on Monday December 15^th , 2025.
