St Kitts and Nevis Weather Forecast

This weather forecast, valid until 8 PM on Saturday, June 14, 2025, predicts predominantly fair and warm conditions for the forecast period. A persistent high-pressure system, combined with diminished atmospheric moisture, will suppress significant shower activity. While a slight chance of showers exists overnight, sunny skies are expected to prevail throughout Saturday. Temperatures will peak around 33°C (91°F) during the day and dip to a comfortable 23°C (73°F) at night, providing a pleasant diurnal temperature variation.

The dominant weather feature is the high-pressure ridge, a region of descending air that inhibits cloud formation and precipitation. High-pressure systems are typically associated with stable atmospheric conditions and fair weather. The reduced moisture content in the atmosphere further contributes to the suppression of shower development. This combination creates an environment conducive to mostly clear skies and abundant sunshine. While a small possibility of isolated showers remains for tonight, the overall probability is low, at only 20 percent. This suggests that any showers that do form will likely be brief and localized.

Winds are expected to be moderate, blowing from the northeast to east at speeds between 15 and 30 km/h (9 to 18 mph), with potential gusts reaching up to 48 km/h (30 mph). These winds, originating over land, will contribute to the relatively low humidity and discourage cloud formation. The wind direction also indicates the absence of any significant weather systems approaching from the east. The moderate wind speeds will provide a comfortable breeze, tempering the warm temperatures during the day.

Sea conditions are forecast to be relatively calm, with wave heights ranging from 1.2 to 1.8 meters (4 to 6 feet). This suggests that the influence of the high-pressure system extends over the marine environment, suppressing wave development. The calm seas will create favorable conditions for recreational activities such as boating and swimming. The combination of sunny skies, moderate winds, and calm seas will create an ideal environment for outdoor activities.

The sunrise and sunset times further illuminate the prevailing weather patterns. Sunrise is predicted for 5:36 AM, while sunset is anticipated at 6:46 PM. These times reflect the typical diurnal cycle for this time of year, with long daylight hours providing ample opportunity to enjoy the pleasant weather. The extended daylight hours are a result of the Earth’s axial tilt and the sun’s position relative to the observer’s location.

In summary, the forecast predicts a period of fair and warm weather dominated by a high-pressure ridge and reduced atmospheric moisture. While a slight chance of isolated showers exists tonight, predominantly sunny conditions are expected for Saturday. Moderate northeast to east winds will prevail, and sea conditions will remain calm. The forecast suggests ideal conditions for outdoor activities, with long daylight hours and comfortable temperatures. This comprehensive weather update provides a clear and detailed picture of expected atmospheric conditions, allowing individuals to plan their activities accordingly and enjoy the pleasant weather.
