St Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to a 24-hour period commencing at 8 am on December 31, 2024, and concluding at 8 am on January 1, 2025. The forecast highlights the influence of a high-pressure ridge, which is responsible for suppressing significant shower activity and fostering relatively stable and cool atmospheric conditions across the islands. This high-pressure system acts as a stabilizing force, limiting the potential for substantial weather fluctuations and creating a predominantly calm and dry environment. The presence of this ridge suggests a period of settled weather, where significant changes in temperature or precipitation are unlikely.

The forecast for December 31, 2024, predicts partly sunny skies throughout the day, with only a slight chance (20%) of brief, light showers. This indicates that while there is a possibility of isolated and short-lived rainfall, the overall weather pattern leans towards dry and sunny conditions. The expected temperature range spans from a high of 30°C (86°F) to a low of 18°C (64°F), suggesting a comfortable, although somewhat cool, diurnal temperature variation. The combination of partly sunny skies and moderate temperatures paints a picture of pleasant daytime conditions, suitable for outdoor activities with minimal risk of significant rainfall.

As the day transitions into the night of December 31st, the forecast predicts fair to partly cloudy skies and chilly conditions. This suggests that cloud cover will remain relatively sparse, allowing for some visibility of the night sky. The term “chilly” implies a noticeable drop in temperature compared to the daytime high, encouraging residents and visitors to prepare for cooler evening conditions. This transition to cooler temperatures is typical of the diurnal temperature cycle, particularly under the influence of a high-pressure system which promotes radiative cooling at night.

Wind conditions are expected to be primarily from the east-northeast, with speeds ranging from 7 to 19 km/h (5 to 12 mph). These relatively light winds will contribute to the calm and stable atmospheric conditions. The forecast also notes lighter wind spells overnight, suggesting further reduction in wind speed during the night hours. This reinforces the overall prediction of calm and settled weather conditions, with minimal disruption from strong winds.

Ocean conditions are characterized by northerly swells, reaching heights of 1.5 to 2.1 meters (5 to 7 feet). This significant swell height has prompted the continuation of a high surf advisory, cautioning against potentially hazardous conditions for swimmers and boaters. The presence of these swells underscores the importance of adhering to safety guidelines and avoiding unnecessary risks in coastal areas. The northerly direction of the swells indicates the origin of the wave energy and can be used to predict their potential impact on different parts of the coastline.

The forecast also provides information on sunset and sunrise times. Sunset on December 31, 2024, is predicted for 5:48 pm, while sunrise on January 1, 2025, is expected at 6:41 am. These timings provide a useful reference for planning outdoor activities and understanding the duration of daylight and darkness. The relatively early sunset and late sunrise are characteristic of the time of year, reflecting the Earth’s axial tilt and its position in orbit around the sun. This information contributes to a comprehensive overview of the anticipated weather conditions and astronomical events during the forecast period. In conclusion, the forecast paints a picture of stable, cool, and predominantly dry conditions for the 24-hour period, with light winds, moderate temperatures, and the persistence of a high surf advisory due to northerly swells.
