St Kitts and Nevis Weather Forecast

This detailed weather forecast, valid until 8:00 am on Saturday, February 1st, 2025, predicts generally settled conditions for the remainder of January 31st, 2025, influenced by a persistent ridge system that limits shower activity. Despite the prevailing stability, the forecast acknowledges the possibility of brief, isolated showers due to pockets of moisture carried by the wind flow. The daytime is expected to be mostly fair, with a slight 20% chance of showers. As evening approaches and transitions into the early morning hours of February 1st, the cloud cover will increase, leading to partly cloudy skies and a moderate 40% chance of showers. Temperatures are expected to reach a high of 30°C (86°F) and a low of 22°C (72°F).

The forecast highlights the influence of easterly winds, which are predicted to blow at speeds between 17 to 31 km/h (10 to 20 mph), with potential gusts reaching up to 46 km/h (29 mph). These winds contribute to moderately rough sea conditions, with wave heights ranging from 1.8 to 2.4 meters (6 to 8 feet). This poses a cautionary note for small craft operators, advising them to exercise caution due to the potentially challenging sea state. The sunset is anticipated at 6:06 pm, while the sunrise the following morning is expected at 6:42 am.

The dominant weather feature influencing this forecast is the presence of a ridge of high pressure. Ridges are associated with sinking air, which inhibits the development of clouds and precipitation. This explains the predominantly fair weather conditions predicted for January 31st. However, the forecast also mentions the presence of pockets of moisture embedded within the wind flow. These pockets of moisture, despite the overall stability, can lead to the formation of isolated showers. The increasing cloud cover and higher chance of showers overnight into the early morning of February 1st suggest a potential weakening of the ridge or the approach of a weak disturbance.

The wind conditions, characterized by easterly winds with moderate speeds and higher gusts, are typical for this time of year. The direction of the wind indicates the origin of the air mass, which in this case is coming from the east. The higher gusts are likely associated with localized variations in terrain or atmospheric instability. The sea state, with waves reaching up to 2.4 meters (8 feet), reflects the influence of the wind on the ocean surface. Small craft operators are particularly vulnerable to these conditions, as their vessels are more susceptible to being capsized or experiencing difficulty navigating in rough seas. Hence, the cautionary advice for them to exercise caution.

The forecast provides important information for planning activities, both on land and at sea. The mostly fair weather during the day is conducive to outdoor activities, but the slight chance of showers suggests the need to be prepared for brief periods of rain. The increasing cloud cover and higher chance of showers overnight into the early morning hours warrant taking precautions for potential wet weather. The rough sea conditions necessitate caution for small craft operators, who should carefully assess the risks before venturing out.

In summary, the forecast presents a picture of generally settled conditions for January 31st, 2025, punctuated by the possibility of isolated showers due to pockets of moisture within the wind flow. The influence of the ridge of high pressure is the dominant factor, leading to mostly fair skies during the day. The increasing cloud cover and higher chance of showers overnight into early February 1st suggest a potential change in the atmospheric setup. The easterly winds, with moderate speeds and potential gusts, contribute to moderately rough seas, requiring caution from small craft operators. The temperature range, from a high of 30°C (86°F) to a low of 22°C (72°F), reflects a relatively warm climate for this time of year. The sunset and sunrise times provide valuable information for planning activities around daylight hours. Overall, the forecast offers a comprehensive overview of the expected weather conditions, allowing individuals to make informed decisions based on the prevailing and anticipated meteorological situation.
