St Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to a specific geographic region, likely an island or coastal area, for a 48-hour period commencing on June 27, 2025, and ending on the evening of June 28, 2025. The forecast highlights the influence of a tropical wave interacting with existing moderate to fresh winds, leading to an increasing likelihood of showers. Temperatures are expected to remain warm, ranging from a high of 32°C (90°F) to a low of 23°C (73°F), contributing to the overall humid and potentially unsettled weather conditions.

The primary driver of the predicted weather pattern is the passage of a tropical wave. Tropical waves are elongated areas of relatively low air pressure that travel westward across the tropics, often serving as the precursors to more organized tropical cyclones. These waves carry with them increased moisture and atmospheric instability, creating favorable conditions for shower development. The interaction of the tropical wave with the prevailing moderate to fresh easterly winds further enhances the potential for shower activity.

On the night of June 27, 2025, the forecast predicts partly cloudy skies with a slight chance of showers, quantified as a 20% probability. This suggests that while some areas might experience brief showers, the overall coverage is expected to be limited. The prevailing winds are expected to continue from the east at speeds between 19 and 35 km/h (12-22 mph), with potential gusts reaching up to 52 km/h (32 mph). These winds will contribute to the continued transport of moisture and instability across the region.

The forecast for June 28, 2025, indicates a significant increase in the likelihood of showers, with a 70% probability. This suggests that more widespread and potentially heavier showers are anticipated throughout the day. The partly cloudy conditions will likely persist, interspersed with periods of rain. The wind conditions are expected to remain similar to the previous night, with easterly winds ranging from 19 to 35 km/h (12-22 mph) and possible gusts up to 52 km/h (32 mph). These gusty winds, combined with the increased rainfall, may lead to localized disruptions.

Marine conditions are also addressed in the forecast, with sea states expected to range from 1.2 to 1.5 meters (4 to 5 feet). While these wave heights are not excessively high, the forecast advises small craft operators to exercise caution. This precaution is likely due to the combined effects of the wind, potential for reduced visibility due to showers, and the possibility of sudden changes in sea conditions associated with the passage of the tropical wave.

The forecast concludes with information regarding sunrise and sunset times for June 28, 2025. Sunrise is predicted to occur at 5:39 am, and sunset at 6:49 pm. These times provide context for the duration of daylight hours and contribute to a comprehensive understanding of the overall weather scenario. The forecast, valid until 8 pm on June 28, 2025, provides a detailed outlook of the expected weather conditions, allowing residents and visitors to prepare accordingly for the potential impacts of the approaching tropical wave. The information regarding wind speeds, sea state, and the likelihood of precipitation are crucial for planning outdoor activities and ensuring safety during this period.
