St. Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to a specific 24-hour period, commencing on August 25, 2025, and concluding at 8 PM on August 26, 2025. The forecast highlights the prevailing influence of a high-pressure ridge dominating the region, promoting stable atmospheric conditions and limiting the likelihood of shower activity. Temperatures are expected to peak at a high of 32 degrees Celsius, equivalent to 90 degrees Fahrenheit, offering warm daytime conditions. Nighttime temperatures will dip to a comfortable low of 25 degrees Celsius, or 77 degrees Fahrenheit, providing a pleasant reprieve from the daytime heat.

The overarching theme for both the night of August 25th and the day of August 26th is partly cloudy skies. The probability of showers remains low, estimated at 20%, categorized as a slight chance. This suggests that while isolated showers cannot be entirely ruled out, the predominant expectation is for dry conditions. The consistent outlook for both periods underscores the sustained influence of the high-pressure system, suppressing significant atmospheric instability and minimizing the potential for widespread precipitation.

Winds are forecast to originate from the east, blowing at speeds ranging from 17 to 30 kilometers per hour (10 to 18 miles per hour). The forecast also mentions lighter spells overnight, indicating that wind speeds will decrease during the nighttime hours. This shift in wind intensity is typical of diurnal variations, where daytime heating and nighttime cooling influence atmospheric circulation patterns. The consistent easterly direction of the wind further supports the presence of the high-pressure ridge steering wind flow across the islands.

Sea conditions are predicted to be moderately calm, with wave heights ranging from 1.5 to 2.1 meters (5 to 7 feet). The presence of northerly swells, reaching up to 1.5 meters (5 feet), adds another layer of detail to the marine forecast. These swells are likely generated by distant weather systems and propagate across the ocean, eventually impacting the local sea state. The combination of moderate wave heights and northerly swells creates a relatively predictable marine environment for maritime activities.

The forecast provides the timing for sunrise and sunset on August 26th. Sunrise is expected at 5:56 AM, marking the beginning of daylight hours. Sunset is predicted for 6:30 PM, signaling the end of daylight and the transition to nighttime. These times offer valuable information for planning outdoor activities and understanding the cycle of daylight and darkness during this period. The relatively early sunset is characteristic of late summer in the northern hemisphere.

In summary, this comprehensive weather forecast paints a picture of stable and predominantly dry conditions for the forecast period. The influence of a high-pressure ridge suppresses shower activity, resulting in partly cloudy skies and a slight chance of isolated showers. Temperatures are expected to be warm during the day and comfortably cool at night. East winds will prevail, with lighter spells expected overnight. Sea conditions are forecast to be moderately calm with northerly swells. The forecast also provides the timing for sunrise and sunset on August 26th, adding further detail to the overall weather picture. This detailed forecast provides valuable information for residents and visitors to plan their activities accordingly.
