St. Kitts and Nevis Meteorological Forecast

This weather forecast, valid until 8 PM on Friday, August 29, 2025, pertains to the Leeward Islands and outlines the expected meteorological conditions for the remainder of August 28th and the day of August 29th. The dominant weather feature is a transitioning weather pattern. An upper-level trough, a region of relatively low atmospheric pressure, is shifting westward, making way for a building ridge of high pressure. High-pressure systems are generally associated with stable atmospheric conditions and fair weather. However, the forecast indicates that the influence of the departing trough will still be felt in the form of lingering moisture and atmospheric instability. This residual instability, coupled with a moderate easterly breeze, will contribute to the continued possibility of showers.

The temperature forecast for August 28th predicts a high of 31 degrees Celsius (88 degrees Fahrenheit) and a low of 26 degrees Celsius (79 degrees Fahrenheit). This temperature range is typical for the region during this time of year. The overnight period on August 28th is anticipated to be partly cloudy, with a 60% chance of showers, characterized as a “moderate” probability. This suggests a relatively high likelihood of experiencing at least some rainfall during the night.

The forecast for August 29th predicts partly cloudy conditions with a 40% chance of showers, also classified as a “moderate” probability. Although the chance of showers decreases slightly compared to the previous night, the possibility of rainfall remains. The persistent cloud cover and the chance of showers suggest that the influence of the departing trough and its associated moisture will continue to affect the region’s weather. The wind conditions are predicted to be from the east at speeds between 13 to 26 kilometers per hour (8 to 16 miles per hour), with periods of lighter winds expected during the night. This moderate easterly breeze will contribute to the transport of moisture and likely influence the formation and movement of any showers.

The sea state is forecast to be relatively calm, with wave heights ranging from 0.9 to 1.2 meters (3 to 4 feet). This suggests generally favorable conditions for marine activities. The sunrise on August 29th is predicted to occur at 5:57 AM, while sunset is expected at 6:27 PM, providing approximately 12.5 hours of daylight. These times are consistent with the late summer period in the Northern Hemisphere.

In summary, the forecast indicates a transition from a more unsettled weather pattern associated with the upper-level trough to a more stable regime influenced by the building high-pressure ridge. However, the lingering effects of the trough, including moisture and instability, will maintain the chance of showers throughout the forecast period. The combination of partly cloudy skies, moderate easterly winds, and a moderate chance of showers suggests a generally humid and slightly unsettled weather pattern for the Leeward Islands. While the chance of showers decreases slightly from the night of August 28th to the day of August 29th, the possibility of rainfall remains throughout the forecast period. The relatively calm sea state offers favorable conditions for marine activities.

The forecast offers a comprehensive overview of the expected weather conditions for the Leeward Islands, covering temperature, cloud cover, precipitation probability, wind speed and direction, sea state, and sunrise/sunset times. This information allows residents and visitors to plan their activities accordingly, taking into account the possibility of showers and adjusting their outdoor plans as needed. The detailed description of the atmospheric conditions, including the transitioning weather pattern from a trough to a ridge, provides a deeper understanding of the factors influencing the forecast. The moderate wind speeds and relatively calm seas further refine the picture of the expected weather conditions. The inclusion of sunrise and sunset times adds another layer of detail for planning outdoor activities.
