Today's Forecast
Updated: 01 September 2026 | 6:00 a.m.
SYNOPSIS:
A low-level trough is expected to move slowly across the western Caribbean from this evening. Ahead of this feature, increasing moisture will interact with an upper-level low over the Cayman area, supporting showers from later this afternoon. A weakening pressure gradient will also result in lighter winds, which, combined with daytime heating, may support additional shower development. Satellite imagery shows few low-level clouds streaming from the Sister Islands moving towards the west-southwest.
FORECAST:
Today: Partly cloudy skies with cloudy spells and a 40% chance of showers with some thunder later this afternoon. Temperatures will rise near the low to mid 90's °F, with a heat index of 109 °F. Winds will be northeast at 5 to 10 knots at first, becoming east to southeast and occasionally variable by the afternoon. Seas will be slight with wave heights of 1 to 3 feet
Tonight: Partly cloudy skies with cloudy spells moving in by the early morning and a 30% chance of showers with some thunder. Temperatures will fall near the low 80's °F. Winds will be southeasterly at 5 knots or less. Seas will be smooth with wave heights less than 2 feet.
