St Kitts and Nevis Meteorological Forecast

This weather forecast pertains to a specific 48-hour period, commencing on September 24, 2025, and concluding at 8:00 p.m. on September 25, 2025. The forecast highlights the lingering effects of a recently passed tropical wave, which has left behind a blanket of moisture and atmospheric instability. These conditions are the primary drivers behind the predicted weather pattern, characterized by periods of cloud cover and scattered showers. The forecast anticipates a high temperature of 31°C (88°F) and a low of 23°C (73°F) during this period. This relatively small temperature range suggests a consistently warm and humid environment, typical of tropical or subtropical climates influenced by oceanic conditions.

The forecast for the night of September 24, 2025, predicts partly cloudy skies with a moderate 40% chance of showers. This indicates that while some areas may experience rainfall, it is not expected to be widespread or continuous throughout the night. The presence of cloud cover will likely contribute to a warmer overnight temperature, preventing significant radiative cooling. This forecast suggests a relatively comfortable night, although the possibility of showers should be considered when planning outdoor activities.

Looking ahead to September 25, 2025, the forecast anticipates a continuation of the partly cloudy skies and a slightly increased chance of showers, rising to 60%. This elevated probability of rain is attributed to the combined effects of light winds and daytime heating. Light winds prevent the rapid dispersal of moisture and clouds, while daytime heating increases atmospheric instability, leading to the development of convective showers. The forecast suggests that while showers are more likely on Thursday, they will still be scattered in nature, with sunny breaks interspersed between periods of rainfall.

The wind conditions are predicted to be predominantly east-southeast, ranging from 9 to 26 km/h (6 to 16 mph). These relatively light winds are consistent with the overall weather pattern, contributing to the localized nature of the predicted showers. Lighter wind spells are also anticipated, suggesting periods of relative calm. These gentle breezes, combined with the warm temperatures, create a pleasant environment, although the increased humidity from the tropical wave may make the air feel slightly heavier.

Sea conditions are expected to be relatively calm, with wave heights ranging from 0.9 to 1.2 meters (3 to 4 feet). These calm seas are favorable for marine activities such as boating and swimming, although caution should always be exercised, especially given the possibility of localized showers. The moderate wave heights also suggest a relatively stable atmospheric pressure system, further supporting the prediction of scattered showers rather than widespread heavy rainfall.

Finally, the forecast provides the sunrise and sunset times for Thursday, September 25, 2025. Sunrise is predicted at 6:01 a.m., while sunset is expected at 6:05 p.m. These times indicate a near-equal split between daylight and nighttime hours, typical for this time of year in many parts of the world. The timing of sunrise and sunset can be useful for planning outdoor activities, particularly those sensitive to light conditions, such as photography or stargazing. Overall, this forecast paints a picture of a relatively mild and predictable weather pattern, characterized by warm temperatures, partly cloudy skies, and scattered showers, primarily influenced by the residual effects of a passing tropical wave.
