St Kitts and Nevis Weather Forecast

This detailed weather forecast, valid until 8:00 AM on Sunday, January 19, 2025, paints a picture of a moderately unstable atmospheric environment over a 24-hour period. The forecast, issued on January 18, 2025, highlights the interplay of low-level instability and moisture within the prevailing wind flow as the driving force behind the anticipated unsettled weather. This combination creates conditions ripe for the development of showers, impacting both daytime and nighttime periods. Temperatures are expected to range from a pleasant high of 30°C (86°F) to a comfortable low of 23°C (73°F), indicative of a generally warm climate. The overall sky condition is predicted to be partly cloudy, allowing for periods of sunshine interspersed with cloud cover.

The forecast specifies a 40% chance of passing showers during the daytime hours. This “moderate” probability suggests that while showers are possible, they are not guaranteed and are likely to be scattered and short-lived. The cloud cover, described as “partly cloudy,” further reinforces this expectation of intermittent sunshine breaking through the cloud layer. This combination of partly cloudy skies and a moderate chance of showers suggests a day suitable for outdoor activities, albeit with the awareness of potential passing showers. Individuals planning outdoor activities should consider having a light raincoat or umbrella readily available.

As the day transitions into night, the chance of showers increases to 60%, also categorized as a “moderate” probability. While this higher percentage suggests a slightly greater likelihood of showers during the night, it still doesn’t indicate continuous rainfall. The increased probability could be attributed to the further development of instability overnight as the land cools, potentially enhancing shower formation. The forecast maintains the “partly cloudy” sky condition, indicating that even with the increased chance of showers, clear breaks in the cloud cover are still expected.

The wind forecast predicts east-northeast winds with speeds ranging from 9 to 28 km/h (6 to 17 mph). This moderate wind speed and direction suggest a relatively calm wind pattern, contributing to a comfortable overall feel despite the potential for showers. The east-northeast direction indicates the origin of the air mass and can influence the moisture content and temperature, contributing to the formation of showers. This moderate wind is unlikely to pose any significant disruption to daily activities.

The marine forecast indicates sea conditions with wave heights ranging from 1.5 to 2.1 meters (5 to 7 feet). These wave heights suggest relatively calm seas, suitable for most marine activities. The moderate wave heights are consistent with the predicted moderate wind speeds, indicating a stable marine environment. Boaters and those engaging in water activities should still exercise caution and be mindful of changing weather conditions, particularly the possibility of passing showers.

The provided sunset and sunrise times, 5:59 PM and 6:44 AM respectively, further contextualize the forecast period. These timings offer a sense of the daylight hours and the transition between day and night. The relatively early sunset and late sunrise are typical for this time of year, reflecting the Earth’s axial tilt and its influence on daylight duration. The forecast concludes its validity at 8:00 AM the following day, just after sunrise, ensuring coverage through the night and into the early morning hours. This comprehensive forecast provides a clear picture of the expected weather conditions, allowing individuals to plan accordingly.
