St. Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to a specific 24-hour period commencing at 8:00 am on January 22, 2025, and concluding at 8:00 am on January 23, 2025. The forecast highlights the influence of a robust Atlantic high-pressure system, which is the primary driver of the predicted weather conditions. This high-pressure system generates fresh to brisk easterly winds that transport moisture across the island region, leading to an elevated likelihood of shower activity throughout the forecast period. Temperatures are expected to range from a high of 30°C (86°F) to a low of 21°C (70°F), indicating a relatively warm, albeit potentially damp, climate.

The daytime forecast on January 22, 2025, calls for partly cloudy skies interspersed with brief periods of increased cloud cover. There is a moderate 60% chance of passing showers, which are expected to be short in duration. These showers are a direct result of the moisture being carried by the easterly winds interacting with the local atmospheric conditions. The combination of partly cloudy skies, warm temperatures, and the chance of brief showers suggests a typical tropical weather pattern influenced by the dominant high-pressure system.

As night falls on January 22, 2025, the weather pattern remains largely consistent with the daytime forecast. Partly cloudy skies will persist, punctuated by short periods of increased cloudiness. The chance of showers remains at a moderate 60%, indicating a continued likelihood of brief, passing showers throughout the night. The nighttime temperatures will drop to a comfortable low of 21°C (70°F).

The forecast emphasizes the significant influence of the strong Atlantic high-pressure system on wind conditions. East winds are predicted to blow at speeds ranging from 22 to 39 km/h (14 to 24 mph). However, during showers, as well as over open waters and in elevated terrains, wind speeds can reach as high as 52 km/h (32 mph). These strong winds, combined with the prevailing easterly direction, are indicative of the powerful high-pressure system driving the weather pattern.

The marine forecast warns of relatively rough sea conditions. Wave heights are expected to range from 1.8 to 2.8 meters (6 to 9 feet), with swells reaching up to 1.8 meters (6 feet). These conditions warrant both a high surf advisory and a small craft advisory, indicating potentially hazardous conditions for coastal activities and small vessels. The high surf advisory warns of strong breaking waves and dangerous rip currents along the coast, while the small craft advisory cautions against venturing into open waters in small boats due to the rough seas and strong winds.

The forecast concludes by providing the times for sunset on January 22, 2025, and sunrise on January 23, 2025. Sunset is expected at 6:01 pm, marking the end of daylight hours. Sunrise will occur at 6:44 am the following day, signifying the beginning of a new day with continued influence from the persistent Atlantic high-pressure system. This information allows for planning outdoor activities and provides a general timeframe for the transition between daylight and nighttime hours. The consistency in the weather pattern throughout the 24-hour period underscores the dominant role of the high-pressure system in shaping the meteorological conditions.
