St Kitts and Nevis Meteorological Forecast

This detailed weather forecast, valid until 8 pm on Saturday, May 24, 2025, predicts generally fair to partly cloudy conditions for the forecast period, with a moderate chance of brief passing showers. The forecast highlights the influence of a relatively stable airmass prevailing across the area, which would typically suggest settled weather. However, the presence of shallow low-level patches moving across the region, carried by a moderate to fresh trade wind flow, introduces the possibility of localized shower activity. This dynamic interplay between stable air and low-level moisture creates conditions conducive to brief, intermittent showers over and around the islands during the next 24 hours.

For the remainder of today, May 23, 2025, the forecast anticipates fair to partly cloudy skies overall. This suggests a predominantly clear sky with occasional cloud cover, indicating relatively pleasant weather conditions. Temperatures are expected to reach a high of 32°C (90°F) and drop to a low of 23°C (73°F), reflecting a comfortable diurnal temperature range. The moderate chance of showers is maintained through the night, although the predominantly fair skies suggest that any shower activity will likely be isolated and of short duration.

Looking ahead to tomorrow, May 24, 2025, the forecast predicts partly sunny skies interspersed with brief cloudy spells. This implies a mixture of sunshine and cloud cover, with the potential for temporary increases in cloudiness. The probability of a short passing shower stands at 40%, characterizing the chance as moderate. This indicates a reasonable likelihood of experiencing a brief shower at some point during the day, but not necessarily a widespread or prolonged period of rainfall. The forecast emphasizes the transient nature of these showers, characterizing them as “short” and “passing,” suggesting they will be relatively localized and quickly move through the area.

The wind forecast calls for easterly winds at speeds ranging from 15 to 30 km/h (9 to 18 mph). These moderate to fresh trade winds will be a defining feature of the weather pattern, contributing to the movement of the low-level moisture patches that have the potential to produce showers. Gusts of wind up to 46 km/h (29 mph) are expected, primarily over open waters and in elevated areas. This highlights the potential for stronger, localized winds in these exposed locations. Mariners and those engaging in activities in elevated areas should be mindful of these potentially stronger gusts.

Sea conditions are predicted to be moderate, with wave heights ranging from 1.2 to 1.8 meters (4 to 6 feet). These relatively calm sea conditions are typical for the forecast period and pose no significant maritime hazards. However, boaters should always exercise caution and be aware of changing weather conditions, especially given the forecast for gusty winds. The combination of moderate seas and gusty winds may create locally choppy conditions, particularly in open waters.

Finally, sunrise tomorrow, May 24, 2025, is predicted for 5:37 am, marking the start of daylight hours. Sunset is forecast for 6:39 pm, signaling the end of the day and the return of nighttime. These times provide a framework for the hours of daylight and darkness during the forecast period. Overall, the forecast paints a picture of generally fair weather with a moderate chance of brief, passing showers, influenced by a stable airmass and the movement of shallow low-level moisture across the region on moderate to fresh trade winds. The forecast is valid until 8 pm on Saturday, May 24, 2025.
