St. Kitts and Nevis Meteorological Forecast

The meteorological forecast for September 14, 2025, anticipates unsettled weather conditions due to the combined influence of a weak trough and conducive upper-level atmospheric dynamics. This synergistic effect will destabilize the atmosphere, fostering an environment ripe for shower and thunderstorm activity. The evening forecast predicts partly cloudy skies interspersed with cloudy spells. There is a moderate 60% probability of shower development, accompanied by a 40% chance of thunderstorms. This suggests that while showers are more likely, the possibility of thunderstorms should not be discounted.

As the night transitions into the morning of September 14th, the cloud cover is expected to thicken, resulting in predominantly cloudy conditions. The probability of showers and thunderstorms increases to a moderate 60%, indicating a higher likelihood of precipitation during the morning hours. This elevated chance reflects the continued influence of the weak trough and favorable upper-level conditions, which facilitate the development and intensification of convective activity. The forecast suggests that the morning hours will likely experience periods of rain, potentially accompanied by thunder and lightning.

As the day progresses into the afternoon, a gradual shift towards clearer skies is anticipated. While the cloud cover will partially dissipate, allowing for periods of sunshine, the possibility of showers persists. The chance of showers decreases to a moderate 40%, suggesting a lower likelihood of precipitation compared to the morning hours. This transition indicates a gradual stabilization of the atmosphere, reducing the intensity and frequency of convective activity. However, the lingering presence of favorable atmospheric conditions still allows for the possibility of isolated showers.

The wind forecast predicts easterly winds with speeds ranging from 17 to 31 kilometers per hour (10 to 20 miles per hour). These moderate winds are expected to be accompanied by potential gusts reaching up to 50 kilometers per hour (31 miles per hour). This indicates periods of stronger wind activity interspersed with the prevailing moderate speeds. The easterly direction of the wind suggests the origin of the air mass contributing to the unsettled weather conditions. The potential for higher gusts indicates the presence of atmospheric instability, which can lead to sudden increases in wind speed.

The marine forecast predicts relatively calm sea conditions, with wave heights ranging from 0.6 to 1.2 meters (2 to 4 feet). This suggests generally favorable conditions for marine activities, with minimal wave action expected. The relatively calm seas reflect the moderate wind speeds and the absence of significant swell activity in the forecast area. This information is crucial for mariners and coastal communities, allowing them to plan their activities accordingly.

The sunrise on September 14th is predicted at 5:59 am, while sunset is expected at 6:14 pm. This provides the daylight hours for the day, influencing various activities and natural processes. The timing of sunrise and sunset reflects the Earth’s position in its orbit around the sun and the specific geographical location of the forecast area. This information is relevant for planning outdoor activities, agricultural practices, and understanding the diurnal cycle of temperature and other environmental factors. In summary, the forecast for September 14, 2025, indicates unsettled weather conditions characterized by cloudy skies, moderate chances of showers and thunderstorms, moderate easterly winds with potential gusts, and relatively calm seas. The day is expected to transition from cloudy with higher chances of precipitation in the morning to partly sunny with lower chances of showers in the afternoon.
