St. Kitts and Nevis Meteorological Forecast

This detailed weather forecast, valid until 8 pm on Thursday, June 12, 2025, paints a picture of continuing moderate to fresh breezes across the islands. The forecast anticipates a high temperature of 30°C (86°F) and a low of 25°C (77°F), suggesting a relatively warm, yet comfortable day overall. While the dominant trend is for decreasing moisture and limited shower activity, the persistent breeze introduces an element of unpredictability. This breeze, originating from the east at speeds between 19 and 35 km/h (12 to 22 mph) with potential gusts up to 52 km/h (32 mph), possesses the capacity to generate shallow cloud patches that could drift over the islands intermittently. This dynamic interplay of wind and moisture creates a nuanced forecast that prioritizes caution while acknowledging the overall trend towards drier conditions.

Tonight’s forecast predicts partly cloudy skies with a slight chance (20%) of a brief evening shower. This suggests that while some areas might experience a fleeting shower, the majority of the night will remain dry with intermittent cloud cover. The presence of clouds and a moderate breeze will likely contribute to a comfortable overnight temperature, preventing excessive heat buildup.

Looking towards tomorrow, Thursday, June 12, 2025, the forecast continues the theme of partly cloudy skies, but with a slightly increased chance of precipitation. The probability of a brief afternoon shower rises to 40%, indicating a moderate chance of rain. This suggests a higher likelihood of localized showers developing during the warmer afternoon hours, likely driven by daytime heating and the persistent easterly breeze. While not a guarantee of widespread rainfall, residents and visitors should be prepared for the possibility of a brief shower, particularly during the afternoon.

The persistent easterly breeze, forecast to continue at 19 to 35 km/h (12 to 22 mph) with gusts up to 52 km/h (32 mph), will be a defining characteristic of the weather over the forecast period. This wind, while refreshing, will also contribute to moderately rough sea conditions. The forecast predicts seas of 1.8 to 2.1 meters (6 to 7 feet) with swells of 1.5 meters (5 feet), prompting a continuation of the High Surf Advisory. These conditions warrant caution for all marine activities, particularly for small craft operators who are advised to exercise extra vigilance.

Coastal residents and those planning beach activities should take the High Surf Advisory seriously, remaining aware of the potential for strong currents and dangerous waves. The combination of persistent wind and elevated swells creates hazardous conditions for swimming, surfing, and other water sports. It is recommended to stay informed about local conditions and heed the advice of lifeguards and other authorities. The rough seas also pose a safety risk to boaters, especially smaller vessels, reinforcing the need for caution among small craft operators.

Finally, the forecast provides astronomical information for tomorrow, June 12, 2025. Sunrise is predicted at 5:36 am, marking the beginning of daylight hours, while sunset is expected at 6:45 pm, signaling the end of the day. This provides a useful reference for planning outdoor activities and enjoying the natural beauty of the islands. Overall, the forecast anticipates a continuation of the current weather patterns, characterized by moderate to fresh breezes, partly cloudy skies, and a chance of brief showers. The persistent easterly winds and resulting elevated sea conditions warrant caution for coastal activities and maritime operations.
