St Kitts and Nevis Meteorological Forecast

This detailed weather forecast, valid until 8:00 a.m. on Tuesday, June 10, 2025, predicts a generally stable and hazy atmospheric condition over the forecast area, punctuated by the possibility of brief passing showers. The forecast highlights the interplay of a relatively stagnant air mass and dynamic low-level atmospheric patches carried by moderate to fresh trade winds, creating conditions conducive to shower activity over and around the islands during the next 24 hours. While the overall weather pattern remains steady, these localized patches introduce an element of variability, resulting in a moderate chance of precipitation.

The daytime forecast for June 9, 2025, calls for partly sunny and hazy conditions, interspersed with brief cloudy spells. The likelihood of brief passing showers is estimated at 60%, categorizing it as a moderate chance. Temperatures are expected to reach a high of 32°C (90°F) and drop to a low of 24°C (75°F), providing a relatively comfortable range despite the hazy conditions. The combined effect of sunshine, haze, and potential showers suggests a day characterized by fluctuating weather patterns, requiring preparedness for both sunny and rainy spells.

As the day transitions into night, the forecast predicts a shift towards fair to partly cloudy and hazy conditions. The chance of overnight showers decreases to 40%, still classified as a moderate possibility. This suggests a lower likelihood of precipitation compared to the daytime hours, with clearer skies becoming more prevalent. The continuing haze, however, indicates the persistence of atmospheric particles, potentially impacting visibility.

The wind forecast indicates a consistent easterly flow at speeds ranging from 19 to 33 km/h (12 to 21 mph). Gusts are expected to reach as high as 48 km/h (30 mph), particularly over open waters and in elevated areas. This indicates potentially stronger wind conditions in exposed locations, advising caution for maritime activities and those in higher altitude regions. The sustained easterly winds will likely contribute to the overall stability of the air mass, while the gusts introduce a dynamic element, potentially influencing the movement of the low-level patches responsible for shower activity.

Sea conditions are predicted to be moderately calm, with wave heights between 1.2 and 1.8 meters (4 to 6 feet). This suggests generally favorable conditions for marine navigation, though the presence of gusts may introduce localized choppiness, particularly in open water areas. The interplay of wind and sea conditions further emphasizes the relatively stable yet dynamic nature of the forecast period, where underlying calm conditions are punctuated by periods of increased activity.

The forecast concludes with astronomical information, providing the sunset time for June 9, 2025, as 6:44 p.m. and the sunrise time for June 10, 2025, as 5:36 a.m. These timings delineate the hours of darkness and offer a framework for planning activities around daylight hours. The relatively long duration of daylight is typical for this time of year, contributing to the overall warming trend and influencing atmospheric conditions. Overall, the forecast paints a picture of a relatively stable weather pattern with the potential for localized, brief showers due to the interaction of a hazy air mass, trade winds, and low-level atmospheric disturbances.
