St Kitts and Nevis Weather Forecast

This detailed weather forecast pertains to a 24-hour period commencing on March 17, 2025, and concluding at 8 am on March 18, 2025. The overarching weather pattern is influenced by a weak trough system interacting with light winds, daytime heating, and accessible low-level moisture. These combined factors create an environment conducive to localized shower activity across the islands during this forecast period. Temperatures are expected to reach a high of 32°C (90°F) and drop to a low of 17°C (63°F), reflecting a typical diurnal temperature variation. The general sky condition is predicted to be fair to partly cloudy, indicative of a mix of sunshine and cloud cover.

The forecast for March 17, 2025, anticipates partly sunny skies punctuated by brief periods of cloudiness. There is a moderate 60% chance of localized showers developing throughout the day. This suggests that while showers are possible, they are not expected to be widespread or continuous. Rather, they are likely to be isolated and of relatively short duration. The specific locations and timing of these showers remain uncertain due to their localized nature.

As the day transitions into night, the weather is expected to shift towards mostly fair and cool conditions. The decreased solar heating after sunset will lead to a drop in temperature, creating a cooler ambiance. The reduced cloud cover contributes to the “fair” characterization, suggesting clear or mostly clear skies. This transition indicates a decrease in the likelihood of precipitation during the nighttime hours.

The wind conditions are predicted to be light and variable, ranging from 4 to 9 km/h (2 to 6 mph). This suggests generally calm wind conditions with occasional slight breezes. The variable nature implies shifts in both wind speed and direction. Furthermore, the forecast indicates periods of calm winds, implying completely still air. These light wind conditions contribute to the localized nature of potential showers, as stronger winds would typically distribute precipitation more widely.

The marine forecast predicts northerly swells ranging from 1.5 to 1.8 meters (5 to 6 feet). Due to this elevated wave height, a high surf advisory remains in effect. This warning cautions against venturing into the sea or engaging in coastal activities due to the potential hazards posed by the strong surf. The northerly direction of the swells indicates the origin of the wave energy from the north.

The sunset on March 17, 2025, is scheduled for 6:21 pm, marking the end of daylight hours. The sunrise on March 18, 2025, is predicted for 6:16 am, signaling the beginning of the next day. This data provides context for the diurnal cycle and the transition between daytime and nighttime conditions. The relatively close proximity of sunrise and sunset times reflects the time of year and the latitude of the location.

In summary, this forecast predicts a day of mixed sunshine and cloud cover with a moderate chance of localized showers. The temperatures are expected to be typical for the season, reaching a high of 32°C and a low of 17°C. Winds will be light and variable, with periods of calm conditions. The seas will experience northerly swells, prompting a high surf advisory. As night falls, conditions will transition to mostly fair and cool with decreased chances of precipitation. This detailed forecast provides a comprehensive overview of the expected weather conditions for the specified 24-hour period, allowing residents and visitors to plan their activities accordingly.
