St Kitts and Nevis Weather Forecast

This detailed weather forecast pertains to a specific 24-hour period commencing on June 4, 2025, and extending until 8 pm on June 5, 2025. The forecast highlights the influence of shallow low-level atmospheric patches interacting with moderate to fresh trade winds, creating conditions conducive to intermittent shower activity across the predicted area. Temperatures are expected to range from a high of 32°C (90°F) to a low of 23°C (73°F), indicative of a warm, tropical or subtropical climate. The overall sky condition is predicted to be partly cloudy, with a moderate chance of brief, passing showers both during the day and overnight.

The atmospheric dynamics driving this forecast involve the movement of shallow low-level patches embedded within the prevailing trade wind flow. These patches, likely representing areas of slightly increased moisture and instability, are transported across the region by the trade winds. As these patches interact with the local environment, they can trigger the development of brief, localized showers. The moderate to fresh trade winds, blowing from the east at speeds between 15 to 28 km/h (9 to 17 mph), play a crucial role in both transporting these patches and influencing the overall weather pattern. The wind speeds are expected to decrease overnight, leading to lighter spells, but the general easterly direction will persist.

The forecast for the night of June 4, 2025, predicts fair to partly cloudy skies with a 40% chance of a brief overnight shower. This suggests that while some areas might experience a brief shower, a significant portion of the night will likely remain dry with varying degrees of cloud cover. The 40% probability indicates a moderate likelihood of shower activity, but not a certainty. This probability stems from the unpredictable nature of the interaction between the low-level patches and the local atmospheric conditions.

Looking ahead to June 5, 2025, the forecast anticipates partly sunny skies with a similar 40% chance of brief passing showers. This indicates a day characterized by a mix of sunshine and cloud cover, punctuated by the possibility of short-lived, localized showers. The continued presence of the low-level patches within the trade wind flow maintains the potential for shower development throughout the day. The “brief passing” nature of the showers suggests they are likely to be short in duration and relatively light in intensity.

The marine forecast predicts sea conditions with wave heights ranging from 1.2 to 1.8 meters (4 to 6 feet). This suggests relatively calm sea conditions, suitable for most marine activities. The wave heights are likely influenced by the prevailing trade winds, which, while moderate to fresh, are not strong enough to generate significant wave activity. This makes for generally favorable conditions for boating and other water-based activities.

Finally, the forecast provides astronomical information, stating that sunrise on June 5, 2025, will occur at 5:36 am, and sunset will occur at 6:43 pm. This information provides context for the daylight hours and helps to complete the overall weather picture. The timing of sunrise and sunset is determined by the Earth’s rotation and its position in orbit around the sun, and these times vary depending on geographical location and the time of year. This specific sunrise and sunset timing suggests a location within the tropics or subtropics, where daylight hours tend to be relatively consistent throughout the year.
