St Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to the Leeward Islands and is valid from September 21, 2025, until 8 PM on September 22, 2025. The overarching weather pattern is characterized by relatively dry and stable conditions influenced by a weak ridge of high pressure. This atmospheric setup will limit significant shower activity across the islands for the duration of the forecast period. Temperatures are expected to peak around 31°C (88°F) during the day and dip to a comfortable low of 25°C (77°F) at night. The predominant wind direction will be from the east, blowing at speeds between 13 and 26 km/h (8 to 16 mph), maintaining a gentle breeze throughout the islands.

Tonight, the weather is forecasted to be fair to partly cloudy, with a slight 20% chance of scattered showers overnight. This suggests that most locations will remain dry, but there’s a small possibility of brief, light showers developing in some areas. The relatively low chance of precipitation underscores the overall stability of the atmosphere and the influence of the high-pressure ridge. Therefore, residents and visitors can generally expect a pleasant and dry evening with some cloud cover.

Tomorrow, September 22, 2025, the weather is expected to be partly sunny, again with a slight 20% chance of a brief passing shower. This forecast mirrors the overall stable conditions predicted for the period. The “partly sunny” designation indicates a mix of sunshine and cloud cover throughout the day. While there’s a small chance of a quick, light shower, most locations are likely to remain dry. This weather pattern suggests suitable conditions for outdoor activities, although it’s always advisable to be prepared for a brief shower, given the slight possibility.

The maritime conditions are expected to be relatively calm, with sea swells ranging from 0.9 to 1.2 meters (3 to 4 feet). This suggests generally favorable conditions for boating and other water-based activities. The moderate wave heights indicate a relatively calm sea state, providing a comfortable experience for those venturing onto the water. Combined with the predicted light to moderate winds, these sea conditions contribute to an overall pleasant maritime environment.

Sunrise on September 22, 2025, is predicted to occur at 6:01 AM, while sunset is expected at 6:08 PM. This provides approximately 12 hours of daylight, typical for this time of year in the Leeward Islands. These timings allow ample opportunity for daytime activities and contribute to the overall pleasant weather experience.

In summary, the Leeward Islands can expect generally dry and stable weather conditions for the next 24 hours, with a weak ridge of high pressure limiting significant shower activity. Temperatures will be warm and comfortable, ranging from 25°C (77°F) to 31°C (88°F). Winds will be predominantly easterly at 13 to 26 km/h (8 to 16 mph), while seas will remain relatively calm at 0.9 to 1.2 meters (3 to 4 feet). There is a slight chance of brief, passing showers both tonight and tomorrow, but the overall forecast suggests predominantly dry and sunny conditions, ideal for outdoor activities. The sunrise is at 6:01 AM and the sunset is at 6:08 PM, providing approximately 12 hours of daylight. This forecast is valid until 8 PM on Monday, September 22, 2025.
