St Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to a specific, albeit unnamed, island location, valid from May 10, 2025, until 8:00 AM on May 11, 2025. The forecast anticipates a transition from fair to partly cloudy skies throughout the period, with varying chances of brief passing showers. This dynamic weather pattern is attributed to a shallow low-pressure system interacting with moderate to fresh trade winds. The forecast provides insights into temperature fluctuations, wind conditions, sea state, and sunrise/sunset times, offering a comprehensive overview of the expected weather conditions.

The daytime high temperature is projected to reach 32°C (90°F), while the low is expected to dip to 22°C (72°F). This indicates a relatively moderate temperature range typical of tropical or subtropical climates. The presence of a shallow low-pressure system, coupled with the influence of trade winds, creates an environment conducive to shower activity. The probability of these brief showers is estimated at 40% during the daytime hours. This suggests that while showers are possible, they are not guaranteed, and any precipitation is likely to be short-lived.

As evening approaches, the forecast predicts a continuation of fair to partly cloudy skies. However, the chance of brief passing showers increases to 60%. This higher probability suggests that nighttime shower activity is more likely compared to the daytime hours. The increase in shower probability during the night may be attributed to enhanced atmospheric instability or changes in wind patterns that favor the development of convective showers. The forecast specifically mentions “occasional cloudy spells,” indicating that periods of increased cloud cover are expected during the night.

The wind forecast calls for easterly winds at speeds ranging from 15 to 30 km/h (9 to 18 mph) during the day, with anticipated lighter winds overnight. These easterly winds are consistent with the prevailing trade wind pattern, typical of many island locations. The decrease in wind speed overnight is a common occurrence, as the diurnal temperature cycle influences atmospheric pressure gradients and wind patterns. This information is particularly relevant for marine activities and those sensitive to wind conditions.

Sea conditions are predicted to be relatively calm, with wave heights expected to remain between 1 to 1.5 meters (3 to 5 feet). This moderate sea state is generally favorable for boating and other water-based activities. The relatively low wave heights are likely a result of the shallow low-pressure system and the moderate wind speeds. However, it’s important to note that localized variations in sea conditions are always possible, and caution should be exercised when venturing out to sea.

Finally, the forecast provides the timing of sunset and sunrise. Sunset on May 10th is predicted for 6:34 PM, while sunrise on May 11th is expected at 5:40 AM. These times offer valuable information for planning outdoor activities and provide a general sense of the daylight hours. The difference between sunset and sunrise times indicates a relatively short night, typical of locations closer to the equator. This comprehensive forecast offers a detailed overview of the expected weather conditions for the specified period, aiding residents and visitors in planning their activities accordingly. The information provided covers temperature, precipitation probability, wind conditions, sea state, and sunrise/sunset times, painting a complete picture of the anticipated weather scenario.
