However, as the region transitions into the wetter months, a marked decline is observed in June, which sees a drop to 256 hours—the lowest sunshine total of the year.
Despite the reduction in sunlight during the mid-year rainy season, the conditions improve again as the year progresses toward its end. July and August rebound to 312 and 329 hours of sunshine, respectively, revealing a rich return of sunny days that is well-positioned before the onset of the heavier rainfall in September. Throughout the latter months, sunshine hours remain fairly consistent, ranging between 286 and 320 hours, providing ample opportunity for agricultural productivity and recreational activities. This clear seasonal trend highlights the importance of sunshine for both local ecosystems and the lifestyle in Essequibo Islands-West Demerara.
In Essequibo Islands-West Demerara, the Ultraviolet (UV) Index remains consistently high throughout the year, indicating an extreme level of solar radiation exposure. Peaks are recorded from January to April, with UV Index values reaching up to 15 in both March and April. This level of intensity, categorized as extreme, means that individuals are at risk of harm from unprotected sun exposure in just 10 minutes. Such high UV Index readings are particularly significant for outdoor activities, necessitating vigilant sun protection measures to prevent skin damage and long-term health effects.
Following the peak months, UV Index values slightly decrease but remain in the extreme category, with readings of 12 to 14 from July through December. Although there is a slight reduction during the mid-year months, the 10-minute burn time persists, underscoring the need for continued awareness even as the rainy season approaches. This consistent extreme UV exposure underscores the importance of protective measures, such as sunscreen, clothing, and shade, for residents and visitors alike in Essequibo Islands-West Demerara. Understanding these UV trends is vital for promoting skin health and minimizing risks associated with prolonged exposure to sunlight.
