St Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to a 24-hour period commencing at 8 am on March 21, 2025, and concluding at 8 am on March 22, 2025. The forecast anticipates relatively warm temperatures, with a high of 33 degrees Celsius (91 degrees Fahrenheit) and a low of 20 degrees Celsius (68 degrees Fahrenheit). The dominant weather pattern is expected to be fair to partly cloudy, with a moderate chance of brief, localized showers. This pattern is driven by the interaction of a weak trough, light southeasterly winds, and daytime heating, which together create conditions conducive to shower development. However, the forecast predicts a transition to drier and more stable conditions as the night progresses.

During the daytime hours of March 21st, the skies are expected to be predominantly partly sunny, punctuated by brief periods of cloud cover. The probability of experiencing a localized shower is estimated at 40%, indicating a moderate chance. These showers are anticipated to be brief in duration and limited in geographic extent. The combination of partly sunny skies and the potential for showers suggests a dynamic atmospheric environment, with localized variations in weather conditions.

As evening approaches and transitions into the night of March 21st, the weather is expected to become fair to partly cloudy, accompanied by a drop in temperature. The term “cool conditions” suggests that temperatures will be comfortable, likely hovering around the lower end of the predicted range. This shift towards clearer skies and cooler temperatures signifies the stabilization of the atmosphere as the daytime heating effect diminishes.

The wind forecast for this period indicates southeasterly winds ranging in speed from 7 to 19 kilometers per hour (5 to 12 miles per hour). These winds are expected to become variable or calm at times, suggesting fluctuating wind patterns throughout the 24-hour period. The relatively light wind speeds contribute to the overall calm weather pattern, although they play a role in the potential for localized shower development during the day.

The marine forecast predicts sea conditions with wave heights between 1 and 1.5 meters (3 to 5 feet). These relatively calm seas further underscore the generally tranquil weather conditions expected. The combination of light winds and moderate sea states suggests favorable conditions for marine activities, although localized showers could introduce brief periods of slightly more challenging conditions.

Finally, the forecast provides the timing of sunset and sunrise. Sunset on March 21st is predicted to occur at 6:22 pm, marking the transition from daylight to nighttime hours. Sunrise on March 22nd is anticipated at 6:13 am, signaling the beginning of the next day. These timings provide a useful reference for planning activities around daylight hours, and they also reflect the typical diurnal cycle of the region.
