Detailed Weather Forecast and Analysis for Sunday, December 15, 2024, and Monday, December 16, 2024

This comprehensive weather forecast provides a detailed outlook for the period beginning Sunday, December 15, 2024, and extending through the morning of Monday, December 16, 2024. The forecast highlights the influence of atmospheric conditions, specifically the interaction of low-level moisture and trade winds, on the anticipated weather patterns for the region. The primary takeaway is a heightened chance of shower activity, particularly during the overnight hours. The forecast also details temperature ranges, wind conditions, sea state, and sunrise/sunset times.

The prevailing weather pattern over the forecast period is characterized by the presence of pockets of low-level moisture embedded within a moderate to fresh trade wind flow. This atmospheric setup creates favorable conditions for shower development. As these pockets of moisture are carried across the islands by the trade winds, intermittent shower activity is anticipated. The intensity and duration of these showers are expected to be brief, but the overall chance of experiencing showers is elevated, especially during the overnight period.

During the daytime hours of Sunday, December 15, 2024, the weather is predicted to be partly sunny with brief cloudy spells. The chance of encountering brief passing showers is estimated at 60%, categorized as a moderate probability. This suggests that while showers are not guaranteed, there is a significant likelihood of experiencing them at some point during the day. Temperatures are expected to reach a high of 31°C (88°F), providing warm conditions despite the potential for showers. Conversely, the low temperature is projected to be 20°C (68°F), indicating a comfortable drop in temperature during the evening.

As Sunday transitions into Monday, the forecast indicates a shift towards increased cloud cover and a higher probability of showers. The overnight period is predicted to be fair to partly cloudy, with periods of increased cloudiness and a 70% chance of showers, categorized as a high probability. This suggests a greater likelihood of experiencing showers during the night compared to the daytime hours. The overnight temperature will remain relatively cool, consistent with the daytime low.

The wind forecast for the period indicates a consistent east-southeast direction with speeds ranging from 15 to 26 km/h (9 to 16 mph). While the general trend is a moderate to fresh breeze, lighter spells are anticipated at times. This fluctuating wind pattern will contribute to the variable cloud cover and shower activity. The seas are expected to be relatively calm, with heights ranging from 1.2 to 1.8 meters (4 to 6 feet). These conditions are generally favorable for marine activities, although caution should be exercised during periods of increased wind speeds and potential showers.

The forecast concludes with information regarding sunrise and sunset times. Sunset on Sunday, December 15, is scheduled for 5:40 pm, marking the end of daylight hours. Sunrise on Monday, December 16, is predicted for 6:33 am, heralding the start of a new day. This information is relevant for planning outdoor activities and adjusting to changing light conditions. The forecast’s validity extends until 8:00 am on Monday, December 16, 2024, after which an updated forecast would be necessary for continued accuracy.

In summary, the forecast period is characterized by a heightened chance of showers due to the interaction of low-level moisture and trade winds. Daytime hours on Sunday are expected to be partly sunny with a moderate chance of showers, while the overnight period into Monday carries a high chance of showers and increased cloud cover. Temperatures will range from a high of 31°C (88°F) to a low of 20°C (68°F). Winds will be predominantly east-southeast, and seas will remain relatively calm. This comprehensive forecast provides a detailed overview of the anticipated weather conditions, allowing for informed decision-making regarding outdoor activities and preparations for potential shower activity.
