St Kitts and Nevis Weather Forecast

This detailed weather forecast pertains to the Leeward Islands and is valid from January 28, 2025, until 8:00 am on Wednesday, January 29, 2025. The forecast anticipates partly cloudy conditions with a moderate chance of showers throughout the day, transitioning to partly cloudy skies with a slight chance of showers during the night. The driving meteorological force behind this forecast is a surface trough interacting with weak atmospheric instability and available moisture. This combination creates favorable conditions for cloud development and scattered showers across the islands.

Temperatures are expected to peak at a high of 30°C (86°F) and dip to a low of 22°C (72°F), providing a comfortably warm day and a relatively mild night. The wind will be predominantly easterly, blowing at speeds between 15 to 30 km/h (9 to 18 mph), with potential gusts reaching up to 48 km/h (30 mph). These moderate winds could contribute to a slight increase in wave height, with seas predicted to range from 1.2 to 1.8 meters (4 to 6 feet). This suggests generally calm sea conditions, though small craft operators might experience some choppiness.

The forecast highlights the interplay of several atmospheric factors. The surface trough, an elongated area of relatively low pressure, acts as a focal point for converging winds and rising air. This rising air, combined with the presence of moisture, leads to the formation of clouds and the potential for showers. The “weak instability” mentioned suggests that the atmosphere is somewhat conducive to vertical air movement, further enhancing the likelihood of shower development. However, the instability is not strong enough to predict widespread or heavy rainfall.

The 60% chance of showers during the day indicates a moderate probability of experiencing rainfall at any given location within the Leeward Islands. This doesn’t necessarily mean continuous rain, but rather intermittent showers that could vary in intensity and duration across the islands. As the day progresses into night, the chance of showers decreases to 20%, suggesting a lower likelihood of rainfall. This decrease likely reflects the diurnal cycle of atmospheric heating and cooling, with less solar radiation available during the night to drive convective activity and shower formation.

The forecast provides crucial information for residents and visitors of the Leeward Islands, enabling them to plan their activities accordingly. The moderate chance of showers during the day suggests that outdoor activities might be interrupted by brief periods of rain, necessitating the use of umbrellas or rain gear. The relatively calm sea conditions are favorable for boating and other water activities, though caution should be exercised due to the potential for gusty winds.

Finally, the forecast mentions the sunset time for January 28th at 6:05 pm and the sunrise time for January 29th at 6:43 am. This provides a useful reference for planning outdoor activities and appreciating the natural beauty of the islands during these transitional periods. The relatively short duration between sunset and sunrise reflects the time of year and the geographical location of the Leeward Islands. Overall, the forecast paints a picture of generally pleasant weather conditions with a moderate chance of intermittent showers, typical of tropical island climates.
