St. Kitts and Nevis Meteorological Forecast

This detailed weather forecast provides a comprehensive outlook for a specific geographical area, presumably a group of islands, for a 48-hour period spanning July 9 and 10, 2025. The forecast emphasizes the influence of a weak tropical wave traversing the region, resulting in atmospheric conditions conducive to intermittent cloud cover and shower activity. Temperature-wise, the forecast predicts a relatively warm diurnal range, with a high of 32°C (90°F) and a low of 23°C (73°F). This temperature range suggests a tropical or subtropical climate. The forecast is valid until 8 PM on Thursday, July 10, 2025, emphasizing its short-term nature and the potential for evolving weather patterns beyond this timeframe.

The forecast describes the primary driver of the anticipated weather as a weak tropical wave. Tropical waves are elongated areas of relatively low air pressure that move westward across the tropics, often triggering cloud development and precipitation. The “weak” designation suggests that this particular wave is not expected to produce widespread or intense weather events, but rather localized and brief showers. The interaction of this wave with existing moisture in the atmosphere creates instability, meaning the air is prone to rising and condensing, further enhancing the likelihood of shower formation. The overall picture is one of transient weather patterns, with periods of cloudiness and showers interspersed with clearer intervals.

The specific forecast for the night of July 9 predicts partly cloudy skies with a 60% chance of showers. This indicates a moderate probability of precipitation, suggesting that while showers are likely, they may not be continuous or affect all areas equally. The term “partly cloudy” suggests that cloud cover will be variable, allowing for periods of clear sky as well. For July 10, the forecast anticipates similar partly cloudy conditions, but with a slightly lower chance of showers at 40%. This reduction in probability suggests a trend towards drier conditions compared to the previous night. The consistency in cloud cover suggests that the influence of the tropical wave will persist throughout the forecast period.

Wind conditions are expected to be moderate to brisk, blowing from the east at speeds of 19 to 35 km/h (12 to 22 mph). The inclusion of “possible higher gusts of 54 km/h (33 mph)” indicates the potential for short bursts of stronger winds, likely associated with shower activity. Easterly winds are typical of trade winds in tropical and subtropical regions, contributing to the overall climate. The forecast for sea conditions predicts waves ranging from 1.2 to 1.8 meters (4 to 6 feet). This wave height suggests relatively calm seas, though conditions could be locally choppier due to the wind. The information on sea conditions is relevant for maritime activities and coastal communities.

The provided sunrise time of 5:43 am on July 10 contributes to the overall picture of the diurnal cycle. This relatively early sunrise is consistent with the time of year and the likely geographical location within the tropics or subtropics. While not directly related to the prediction of showers or cloud cover, the sunrise time adds context to the forecast, allowing for planning of outdoor activities.

In summary, the forecast paints a picture of transient weather conditions for the 48-hour period, influenced by a weak tropical wave. The forecast anticipates partly cloudy skies throughout, with a moderate chance of showers, decreasing slightly from 60% on the night of July 9 to 40% on July 10. Temperatures are expected to be warm, typical of a tropical or subtropical climate, and winds will be predominantly easterly with potential for higher gusts. Sea conditions are predicted to be relatively calm. This comprehensive forecast provides valuable information for residents and visitors to plan their activities during the specified timeframe, taking into account the likelihood of intermittent showers and the prevailing wind and sea conditions.
