St Kitts and Nevis Meteorological Forecast

This weather forecast, valid until 8 pm on Monday, September 1st, 2025, predicts generally stable conditions for the forecast period. A dominant ridge of high pressure is expected to limit significant shower activity, creating a mostly dry environment. However, the presence of some low-level moisture transported by prevailing winds introduces the possibility of intermittent cloud cover and brief showers. While the overall weather pattern leans towards stability, the influence of this moisture adds a degree of uncertainty, precluding completely rain-free conditions. This interaction between the high-pressure ridge and low-level moisture sets the stage for a partially cloudy forecast with a moderate chance of scattered, short-lived showers.

The forecast for tonight, August 31st, anticipates partly cloudy skies with a 40% chance of showers. This probability indicates a moderate likelihood of rain, suggesting that while some areas may experience showers, others may remain dry. The presence of cloud cover will contribute to relatively mild overnight temperatures. The forecast for tomorrow, September 1st, mirrors the conditions anticipated for tonight, with partly cloudy skies and a similar 40% chance of showers. This continuity in conditions reflects the persistent influence of the high-pressure ridge and the continued presence of low-level moisture.

Winds are expected to be easterly at 11 to 22 km/h (7 to 14 mph). These moderate easterly winds will contribute to the transport of moisture from the ocean, playing a role in the formation of the predicted showers. The relatively gentle wind speeds suggest comfortable conditions for outdoor activities, with minimal disruption from strong gusts. The sustained easterly flow indicates a relatively consistent wind direction throughout the forecast period.

Sea conditions are forecast to be relatively calm, with wave heights ranging from 0.9 to 1.2 meters (3 to 4 feet). These moderate sea conditions are favorable for marine activities such as boating and swimming, with minimal risk of hazardous wave action. The calm seas reflect the influence of the high-pressure system, which typically suppresses significant wave development.

Sunrise on Monday, September 1st, is predicted for 5:57 am, while sunset is expected at 6:25 pm. These timings offer approximately 12 hours and 28 minutes of daylight, reflecting the time of year and the region’s latitude. The transition from darkness to daylight at sunrise and the subsequent descent into darkness at sunset will provide picturesque bookends to the day.

In summary, this forecast predicts generally stable conditions with intermittent cloud cover and a moderate chance of brief showers for both tonight and tomorrow. The dominant influence of a high-pressure ridge suppresses widespread shower activity, but the presence of low-level moisture introduces the possibility of some rainfall. Moderate easterly winds will contribute to the transport of this moisture, while calm sea conditions are expected. The forecast provides a balanced outlook, suggesting a mix of sunny and cloudy periods with a moderate chance of experiencing a brief shower.
