St. Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to the Leeward Islands and British Virgin Islands region, specifically for the period from May 7, 2025, to 8 PM on May 8, 2025. The forecast highlights the influence of a trough system, a region of relatively low atmospheric pressure, which contributes to the moist and unstable atmospheric conditions. This instability promotes the development of clouds and showers, with rainfall accumulations anticipated between 5 to 15 mm (0.2 to 0.6 inch) over the forecast period. Temperatures are expected to reach a high of 31°C (88°F) and a low of 22°C (72°F), indicative of a warm, tropical climate.

The forecast specifies varying conditions throughout the forecast period. Tonight, May 7, 2025, the weather is predicted to be partly cloudy with a 60% chance of showers. This suggests that while cloud cover will be present, there will also be periods of clearer skies. The 60% probability of showers indicates a moderate likelihood of rainfall occurring during the night. Tomorrow, May 8, 2025, the forecast shifts to cloudy conditions with showers and a 40% chance of thunderstorms. The increased cloud cover and presence of showers suggest a higher likelihood of sustained rainfall throughout the day. The 40% probability of thunderstorms indicates a moderate risk of more intense weather events, potentially including lightning, strong winds, and heavier rainfall.

Wind conditions are expected to be from the east, ranging in speed from 7 to 19 km/h (4 to 12 mph). These moderate easterly winds are expected to become lighter and more variable at times, suggesting fluctuations in both wind speed and direction. Sea conditions are anticipated to be relatively calm, with wave heights ranging between 1.0 to 1.5 meters (3 to 5 feet). This wave height suggests generally manageable conditions for marine activities, although localized variations are always possible.

The forecast also provides sunrise and sunset times for May 8, 2025. Sunrise is predicted at 5:42 AM, marking the transition from night to day, while sunset is expected at 6:33 PM, signaling the end of daylight hours. The difference between sunrise and sunset indicates a total daylight duration of approximately 12 hours and 51 minutes. This information is useful for planning outdoor activities and understanding the diurnal cycle of light and temperature.

In summary, the forecast for the Leeward Islands and British Virgin Islands from May 7 to 8 PM on May 8, 2025, predicts cloudy conditions with varying chances of showers and thunderstorms due to a trough influencing the region. Temperatures will remain warm, with a high of 31°C (88°F) and a low of 22°C (72°F). Winds will be predominantly easterly, ranging from 7 to 19 km/h (4 to 12 mph), with periods of lighter and variable conditions. Seas are expected to be relatively calm, with heights between 1.0 and 1.5 meters (3 to 5 feet). Sunrise on May 8, 2025, is predicted at 5:42 AM, and sunset at 6:33 PM.

The forecast underscores the dynamic nature of weather patterns in the region, highlighting the influence of the trough in creating unstable atmospheric conditions. The predicted rainfall amounts, while moderate, are significant enough to warrant attention and preparedness. The inclusion of thunderstorm probabilities emphasizes the potential for more intense weather events. This comprehensive forecast provides valuable information for residents and visitors to the Leeward Islands and British Virgin Islands, enabling them to make informed decisions about their activities and preparations for the forecast period. The information about wind and sea conditions is particularly relevant for marine activities and coastal communities.
