St Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to the Leeward Islands and their surrounding waters, covering the period from February 12, 2025, to the evening of February 13, 2025. The forecast highlights the influence of a moderate to fresh easterly breeze, which is expected to transport shallow clouds and pockets of moisture across the region. This atmospheric setup will contribute to brief cloudy periods interspersed with showers, both tonight and tomorrow. While tonight carries a high (70%) chance of these passing showers, the probability decreases slightly to moderate (60%) for tomorrow. A defining characteristic of this weather system is the persistent breeze, which, in conjunction with the showers, will create hazardous marine conditions, particularly in the waters north and east of the islands.

Temperatures during this period are expected to remain relatively consistent, ranging from a high of 29°C (84°F) to a low of 24°C (75°F), indicative of a warm, tropical climate. While the air temperatures remain fairly steady, the forecast indicates a marked change in sea conditions. Tonight, the seas are predicted to range from 1.8 to 2.4 meters (6 to 8 feet), but are expected to become rougher tomorrow, increasing to 2.8 meters (9 feet). This increase in wave height necessitates the issuance of marine advisories, with a small craft advisory already in effect and a small craft warning anticipated for tomorrow, specifically targeting the waters east of the islands.

The consistent easterly wind, blowing at speeds between 22 to 39 km/h (14 to 24 mph), is a key driver of both the atmospheric and marine conditions. This wind, combined with the moisture being transported over the islands, creates the conditions favorable for the predicted showers. Furthermore, the wind’s influence is amplified over the coastal waters, where higher spells are expected, with potential gusts reaching up to 56 km/h (35 mph), particularly in and around showers. These stronger winds contribute significantly to the roughening seas, posing a hazard to small crafts.

The forecast explicitly warns of hazardous marine conditions primarily affecting the waters north and east of the Leeward Islands. This warning is underscored by the escalating sea state, which progresses from moderately rough tonight to rougher conditions tomorrow. The advisory and subsequent warning for small crafts emphasize the potential dangers posed by these conditions and emphasize the need for caution and preparedness for those venturing out to sea. The forecast emphasizes the importance of adhering to these advisories to ensure safety at sea.

Beyond the immediate weather conditions, the forecast also provides information on sunrise and sunset times for the following day, February 13, 2025. Sunrise is predicted for 6:39 am, while sunset is expected at 6:11 pm. This provides a context of the daylight hours and allows for planning of activities dependent on natural light. This information can be particularly useful for maritime activities, allowing mariners to align their operations with daylight hours, further enhancing safety measures.

In summary, the Leeward Islands are anticipated to experience a period of warm temperatures, brief cloudy periods, and passing showers under the influence of a moderate to fresh easterly breeze. While the air temperatures remain relatively stable, the marine conditions are predicted to deteriorate, with increasing wave heights leading to the issuance of small craft advisories and warnings. The forecast highlights the importance of heeding these warnings, especially for maritime activities, and underscores the need for caution and preparedness in the face of potentially hazardous sea conditions. The provided sunrise and sunset times offer additional context for planning activities, particularly those sensitive to daylight hours.
