St Kitts and Nevis Meteorological Forecast

The provided weather forecast outlines the meteorological conditions expected for a 24-hour period commencing on December 15, 2024, and concluding at 8:00 am on December 16, 2024. The forecast predicts a transition from partly sunny skies with a moderate chance of showers during the day to fair to partly cloudy conditions with a higher chance of showers overnight. Temperatures are anticipated to range from a high of 31°C (88°F) to a low of 20°C (68°F), indicating a relatively mild climate. The primary driving force behind this weather pattern is a moderate to fresh trade wind flow carrying pockets of low-level moisture, which will interact with the islands to produce the predicted shower activity.

A more detailed examination of the daytime forecast reveals a predominance of partly sunny skies interspersed with brief cloudy spells. The chance of precipitation during the day is estimated at 60%, characterized as a moderate probability of brief passing showers. This suggests that while showers are possible, they are likely to be short-lived and localized. The combination of sunshine and cloud cover, along with the moderate temperatures, will contribute to a generally pleasant daytime atmosphere.

As the day transitions into night, the forecast predicts a shift towards fair to partly cloudy conditions with periods of increased cloudiness. This indicates that while some clear skies may be observed, cloud cover will become more prevalent overnight. The chance of showers increases to 70%, classified as a high probability, suggesting that rainfall is more likely during the nighttime hours. The cooler temperatures, combined with the increased likelihood of showers, will result in a damper and potentially chillier nighttime environment.

The wind conditions throughout the forecast period are expected to be predominantly east-southeast, with speeds ranging from 15 to 26 km/h (9 to 16 mph). The forecast also mentions lighter spells at times, suggesting that wind speeds may fluctuate within the given range. This steady trade wind flow is the key factor transporting the moisture-laden air masses that will contribute to the shower activity. The direction and speed of the wind are consistent with typical trade wind patterns, indicating a relatively stable atmospheric circulation.

Sea conditions are predicted to be moderate, with wave heights ranging from 1.2 to 1.8 meters (4 to 6 feet). This indicates relatively calm seas, suitable for most marine activities. The moderate sea state aligns with the moderate to fresh trade wind speeds, suggesting a consistent energy transfer from the atmosphere to the ocean surface.

The forecast concludes with information on sunset and sunrise times. Sunset is predicted for 5:40 pm, marking the end of daylight hours on December 15th. Sunrise is anticipated at 6:33 am on December 16th, signaling the start of a new day. These timings provide context for the overall forecast period and allow for planning activities around daylight availability. The relatively short duration between sunset and sunrise is characteristic of this time of year.

In summary, the forecast for the 24-hour period starting December 15, 2024, predicts a transition from partly sunny with a moderate chance of showers during the day to fair to partly cloudy with a higher chance of showers at night. Temperatures will range from a high of 31°C (88°F) to a low of 20°C (68°F). Moderate to fresh trade winds from the east-southeast will persist, and sea conditions will be moderate. This forecast suggests a generally pleasant day followed by a cooler, potentially wetter night.
