St. Kitts and Nevis Meteorological Forecast

This weather forecast, valid until 8:00 PM on Sunday, August 3, 2025, predicts continued periods of cloudiness and showers across the islands. This weather pattern is attributed to the lingering moisture and instability left in the wake of a passing tropical wave. This residual atmospheric instability, combined with pockets of low-level moisture carried by moderate winds, creates favorable conditions for shower development. Temperatures are expected to reach a high of 31°C (88°F) and a low of 25°C (77°F), indicative of a typical tropical climate. The forecast indicates a moderate chance of showers, estimated at 60%, for both tonight and tomorrow.

Tonight’s weather is predicted to be partly cloudy with a 60% chance of showers. This suggests intervals of cloud cover interspersed with clearer periods. The moderate shower probability signifies a reasonable likelihood of precipitation, although the intensity and duration of showers may vary. Winds are expected to be from the east-southeast at speeds ranging from 15 to 31 km/h (9 to 20 mph). These winds, while moderate, may decrease in strength overnight, leading to calmer conditions.

Tomorrow’s weather will mirror tonight’s conditions, with partly cloudy skies and a 60% chance of showers. This consistency suggests that the atmospheric conditions driving the current weather pattern will persist throughout the forecast period. The combination of lingering moisture, instability, and moderate winds will continue to create the potential for showers across the islands. Temperatures will remain within the typical range for the region, reaching a high of 31°C (88°F) and a low of 25°C (77°F).

The winds are expected to maintain their east-southeast direction, blowing at speeds between 15 to 31 km/h (9 to 20 mph), similar to the previous night. These moderate winds will contribute to the transport of moisture across the islands, supporting the formation of showers. Sea conditions are predicted to be relatively calm, with wave heights ranging from 0.9 to 1.5 meters (3 to 5 feet). This indicates generally favorable conditions for maritime activities, although localized variations in sea state are always possible.

Sunrise is expected at 5:51 AM, marking the beginning of daylight hours. Sunset will occur at 6:43 PM, signaling the end of daylight. The interval between sunrise and sunset provides approximately 13 hours of daylight, typical for this time of year. These times provide a helpful reference for planning outdoor activities and anticipating changes in light conditions.

In summary, the forecast indicates a continuation of the current weather pattern, characterized by periods of cloudiness and a moderate chance of showers. This pattern is driven by the combined influence of lingering moisture from a tropical wave, low-level moisture transport by moderate winds, and atmospheric instability. Temperatures will remain within the typical range for the region. Winds will predominantly be from the east-southeast at moderate speeds, and sea conditions are expected to be relatively calm. The forecast remains valid until 8:00 PM on Sunday, August 3, 2025.
