St. Kitts and Nevis Meteorological Forecast

This extended weather forecast pertains to a specific geographic location, likely a tropical or subtropical region, for the period of September 12th, 2025, to September 13th, 2025, with validity extending until 8:00 PM on the 13th. The forecast outlines anticipated temperature ranges, general atmospheric conditions, precipitation probabilities, wind speeds and directions, sea states, and sunrise/sunset times. The information paints a picture of transitioning weather patterns, moving from relatively stable conditions to increased cloudiness and chances of precipitation associated with an approaching tropical wave.

On September 12th, 2025, the forecast predicts partly cloudy skies with a high temperature of 31°C (88°F) and a low of 24°C (75°F). These temperatures suggest a warm, pleasant day typical of tropical or subtropical climates. The atmospheric conditions are expected to remain stable throughout the day and into the night. However, the forecast hints at a shift towards increased cloud cover early the following morning, attributed to the passage of a tropical wave, which also introduces a slight chance of showers.

The night of September 12th is expected to be partly cloudy with a 20% chance, categorized as a slight chance, of showers. This low probability suggests that while some areas might experience scattered light rainfall, widespread precipitation is unlikely. The increasing cloud cover is a precursor to the approaching tropical wave, which is expected to bring more significant changes to the weather pattern on September 13th.

The forecast for September 13th, 2025, predicts cloudy conditions with showers and a 20% chance of afternoon thunderstorms. This indicates a higher probability of rainfall compared to the previous night, suggesting that the influence of the tropical wave will be more pronounced. The presence of thunderstorms in the forecast introduces the possibility of heavier downpours, potentially accompanied by lightning and gusty winds, although the relatively low probability suggests these storms may be localized and not affect the entire region.

Wind conditions are predicted to be from the east at speeds between 11 and 28 km/h (7 and 17 mph). This moderate easterly wind is consistent with the anticipated passage of the tropical wave, which typically moves from east to west. These wind speeds are generally considered moderate and unlikely to cause significant disruption, but may contribute to a slight increase in wave height and create slightly choppy conditions at sea.

Sea conditions are forecast to be moderate, with wave heights ranging from 0.9 to 1.2 meters (3 to 4 feet). These conditions are typical of the influence of a passing tropical wave and are generally suitable for most marine activities, though caution is always advised. The moderate sea state suggests that boaters and swimmers should be aware of potentially choppy conditions and exercise appropriate safety measures. Finally, the forecast provides sunrise and sunset times for September 13th as 5:59 AM and 6:15 PM respectively. These times provide a general indication of daylight hours and can be useful for planning outdoor activities. The relatively consistent daylight and nighttime hours further suggest a location near the equator.

In summary, the forecast indicates a transition from partly cloudy and stable conditions on September 12th to cloudier skies with increasing chances of showers and potential afternoon thunderstorms on September 13th due to the passage of a tropical wave. Temperatures remain warm, typical of a tropical or subtropical climate, with moderate easterly winds and moderately choppy seas. The forecast provides a comprehensive overview of the expected weather conditions for the specified period, allowing residents and visitors to plan accordingly. The detailed information, including specific temperatures, precipitation probabilities, wind speeds, and sea states, helps create a clear picture of the evolving weather patterns, emphasizing the increasing influence of the approaching tropical wave. This information is crucial for a range of activities, from daily routines to maritime operations and emergency preparedness.
