St. Kitts and Nevis Meteorological Forecast

This detailed weather forecast, valid until 8:00 AM on Tuesday, May 6, 2025, predicts persistent shower activity and cloudy skies over the forecast area. The prevalent atmospheric conditions, characterized by instability and lingering moisture, are expected to continue fueling the development of showers and potential thunderstorms over the next 24 hours. Temperatures will range from a high of 32°C (90°F) to a low of 23°C (73°F), providing a warm and humid environment conducive to convective precipitation. The forecast anticipates a potential rainfall accumulation of 13 to 25 millimeters (0.5 to 1 inch).

For the remainder of May 5, 2025, the forecast indicates mostly cloudy skies with a high probability of showers, estimated at 70%. Furthermore, there is a 40% chance of moderate thunderstorms developing within these showery conditions. This suggests the possibility of localized heavier downpours, accompanied by lightning and potentially gusty winds. The combination of cloud cover and precipitation will likely moderate temperatures, preventing them from reaching the predicted high of 32°C in areas experiencing showers and thunderstorms.

As the day transitions into night, the cloud cover is expected to decrease slightly, becoming partly cloudy. The chance of showers also diminishes to a moderate 60%. While the threat of thunderstorms appears to subside during the night, the continued presence of moisture and instability suggests that shower activity will persist, albeit at a reduced intensity. The lower nighttime temperatures will likely limit the intensity of any developing showers.

Wind conditions throughout the forecast period are predicted to be relatively light, originating from the east-northeast at speeds between 7 and 19 km/h (5 to 12 mph). These winds are expected to become lighter and more variable at times, suggesting periods of calm interspersed with gentle breezes. The relatively light winds will likely minimize the dispersion of the shower activity, potentially leading to localized heavier rainfall accumulations.

Sea conditions are predicted to be relatively calm, with wave heights ranging from 1 to 1.5 meters (3 to 5 feet). These calm sea conditions reflect the generally light wind speeds predicted in the forecast. The absence of strong winds will limit wave development, resulting in relatively smooth seas. This information is particularly relevant for maritime activities, suggesting favorable conditions for boating and other water-based activities.

The forecast provides the timing of sunset on May 5, 2025, at 6:32 PM and sunrise on May 6, 2025, at 5:42 AM. These timings indicate a relatively short night, typical for this time of year. The short duration of darkness combined with the predicted partly cloudy conditions during the night suggests that temperatures will not drop significantly overnight.

In summary, this detailed weather forecast anticipates persistent shower activity and cloudy skies throughout the forecast period, driven by atmospheric instability and abundant moisture. The forecast highlights a 70% chance of showers and a 40% chance of thunderstorms during the day, transitioning to a 60% chance of showers overnight. Temperatures will be moderate, with a high of 32°C and a low of 23°C. Winds are expected to be light and variable, and sea conditions will remain calm. This forecast provides valuable information for planning outdoor activities and mitigating potential impacts from the anticipated shower activity.
