St Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to a specific 24-hour period commencing on May 29, 2025, and concluding at 8 pm on May 30, 2025. The forecast highlights the influence of a converging set of atmospheric conditions that are likely to produce transient shower activity across the predicted region. The primary driver is a tropical wave approaching from the south, the northern fringes of which are interacting with existing pockets of low-level moisture. This interaction, coupled with a moderate to fresh trade wind flow transporting the moisture across the islands, creates an environment conducive to the development of showers. The forecast quantifies the likelihood of these showers as “moderate,” assigning a 60% probability of occurrence.

The temperature forecast for the period indicates a diurnal range typical of tropical climates. The high temperature is predicted to reach 32°C (90°F), while the low is expected to dip to 23°C (73°F). This range suggests a relatively comfortable temperature profile, despite the potential for shower activity. The forecast further specifies that the skies will be predominantly “fair to partly cloudy,” indicating that while cloud cover will be present, significant sunshine is also anticipated. This blend of sunshine and cloud cover is consistent with the predicted shower activity, which is characterized as “brief passing showers.” This description suggests that the rainfall events will be of short duration and interspersed with periods of dry weather.

The overnight forecast, covering the period from the evening of May 29th to the morning of May 30th, predicts “fair to partly cloudy skies initially, with brief cloudy spells and a 60 per cent or moderate chance of brief passing showers mainly after midnight.” This suggests that the early part of the night will be relatively clear, with cloud cover increasing later and bringing with it the possibility of showers. The 60% probability assigned to these showers maintains consistency with the overall forecast for the 24-hour period. The emphasis on “brief passing showers” reinforces the expectation of short-lived rainfall events.

The forecast for May 30th anticipates “partly sunny skies, with brief cloudy spells and a 60 per cent or moderate chance of brief passing showers mainly during the morning.” This suggests a similar pattern to the overnight forecast, with showers more likely in the morning hours. The prediction of “partly sunny skies” indicates a balance between sunshine and cloud cover, contributing to a pleasant daytime temperature profile. As with the overnight forecast, the emphasis on “brief passing showers” suggests that any rainfall will be of short duration and not significantly disruptive.

Wind conditions are predicted to be from the east at 15 to 30 km/h (9 to 18 mph), with lighter spells expected overnight. This moderate easterly wind flow aligns with the forecast’s description of the trade winds transporting moisture across the islands, contributing to the potential for shower development. The lighter winds overnight suggest a potential decrease in shower activity during those hours. Sea conditions are forecast to be relatively calm, with wave heights of 1 to 1.5 meters (3 to 5 feet). This suggests favorable conditions for marine activities, although localized conditions may vary depending on the specific location and proximity to landmasses.

Finally, the forecast provides sunrise and sunset times for May 30th. Sunrise is predicted for 5:36 am, while sunset is expected at 6:41 pm. These timings provide context for the daylight hours and are consistent with the time of year, indicating a relatively long period of daylight. The information on sunrise and sunset times, while not directly related to the precipitation forecast, provides valuable context for planning outdoor activities during the forecast period. In conclusion, the forecast paints a picture of generally pleasant weather conditions with the potential for brief, intermittent showers. The combination of moderate temperatures, partly sunny skies, and moderate winds suggests a comfortable environment, while the chance of showers encourages preparedness for occasional rainfall.
