St Kitts and Nevis Meteorological Forecast

This detailed weather forecast, valid until 8:00 am on Thursday, December 19, 2024, paints a picture of a moderately warm, breezy day with a chance of intermittent showers across the islands. The dominant feature is a consistent trade wind flow, ranging from moderate to fresh, originating from the east. This airflow, coupled with available atmospheric moisture, sets the stage for the potential development of scattered showers throughout both the day and night. While the skies are expected to remain partly cloudy, the presence of these trade winds and moisture creates a 60% chance of precipitation, categorized as a moderate probability. Temperatures will peak at a warm 32°C (90°F) and dip to a comfortable low of 23°C (73°F) during the night.

The marine forecast emphasizes the influence of northerly swells, contributing to moderately rough sea conditions. Wave heights are projected to range between 1.5 and 2.4 meters (5 to 8 feet), posing a potential hazard to smaller vessels. As a result, both a small craft advisory and a high surf advisory have been issued, cautioning mariners and beachgoers about the potentially challenging conditions. The combination of brisk trade winds and northerly swells necessitates heightened vigilance for those venturing out to sea or engaging in coastal activities.

The forecast highlights the interplay of several meteorological elements. The persistent trade winds, originating from the east, transport moisture across the region, creating the possibility of showers. These winds, with speeds ranging between 19 and 35 km/h (12 to 22 mph) and gusts up to 55 km/h (34 mph), contribute to the moderate sea state. The northerly swells further amplify the wave heights, leading to the issuance of the advisories. The partly cloudy conditions suggest that while there will be periods of sunshine, the cloud cover contributes to the chance of showers.

The provided temperature range, with a high of 32°C (90°F) and a low of 23°C (73°F), indicates a moderately warm day transitioning to a comfortable evening. While the daytime temperature is typical for a tropical climate, the relatively cool nighttime temperature suggests a refreshing respite from the daytime heat. This temperature variation is likely influenced by the presence of cloud cover and the moderating effect of the trade winds.

The sunset time of 5:41 pm signals the end of daylight hours, while the sunrise time of 6:35 am the following morning marks the beginning of a new day. These timings reflect the typical diurnal cycle for this time of year. The relatively short duration between sunset and sunrise further emphasizes the seasonal patterns of daylight hours.

In summary, the forecast predicts a partly cloudy day and night with a moderate chance of showers, driven by a consistent trade wind flow and available moisture. The marine conditions are expected to be moderately rough due to northerly swells, leading to small craft and high surf advisories. Temperatures will remain moderately warm throughout the day and transition to a comfortable coolness overnight. The sunset and sunrise times provide a framework for the daily cycle of light and darkness. This comprehensive forecast provides a clear picture of the expected weather conditions, enabling residents and visitors to plan their activities accordingly.
