St. Kitts and Nevis Meteorological Forecast

This detailed weather forecast pertains to a specific geographic region, encompassing a group of islands, for a 48-hour period from August 9, 2025, to August 10, 2025, ending at 8 pm local time. The forecast highlights the interplay of atmospheric moisture, wind patterns, and temperature variations to predict prevailing weather conditions. The dominant weather feature is the presence of low-level moisture pockets carried by a light to moderate wind flow across the islands. This atmospheric configuration creates conditions conducive to shower activity.

Tonight’s weather, spanning the period from the issuance of the forecast until the following morning, is characterized by partly cloudy skies interspersed with transient cloudy spells. These conditions indicate a dynamic atmospheric state where cloud cover varies, allowing for periods of clear sky punctuated by brief periods of increased cloud density. The probability of brief passing overnight showers is assessed at 60%, signifying a moderate chance of precipitation. This suggests that while showers are likely, they are not expected to be continuous or widespread, rather occurring as localized and short-lived events.

The forecast for tomorrow, August 10, 2025, anticipates a similar pattern initially, with partly cloudy skies and a 60% chance of brief early morning showers. This indicates a continuation of the atmospheric conditions prevalent during the night, with the possibility of showers persisting into the early hours of the day. As the day progresses, a transition towards more stable and drier conditions is expected. This transition will manifest as partly sunny skies, signifying a decrease in cloud cover and a reduction in the likelihood of precipitation. This shift suggests the dissipation of the low-level moisture or its movement away from the island region, leading to more settled weather.

The wind forecast for the period predicts an east-southeast direction with speeds ranging from 11 to 26 kilometers per hour (7 to 16 miles per hour). This wind direction suggests the origin of the airflow, possibly carrying moisture from the southeastern sector. The fluctuating wind speeds, with lighter spells expected overnight, indicate variations in wind intensity over the forecast period. These fluctuations could influence the movement and distribution of the moisture pockets, impacting the localization and intensity of showers.

Sea conditions are anticipated to be relatively calm, with wave heights ranging from 1 to 1.5 meters (3 to 5 feet). This indicates a moderate sea state, generally suitable for maritime activities. The relatively calm sea state is consistent with the light to moderate wind speeds predicted, further supporting the overall picture of relatively benign weather conditions.

Finally, the forecast provides astronomical information: sunrise tomorrow at 5:53 am and sunset at 6:40 pm. This information provides the duration of daylight hours, further contextualizing the weather forecast and aiding in planning activities. The timing of sunrise and sunset also reflects the seasonal position, offering insights into the overall climate of the region during this time of year. Overall, the forecast paints a picture of generally mild weather conditions with moderate chances of intermittent showers, primarily during the night and early morning, transitioning to drier and sunnier conditions later in the day. The forecast combines atmospheric analysis, wind predictions, and sea state information to provide a comprehensive outlook for the specified period.
