Sunshine duration in Ahafo, Ghana, demonstrates a clear seasonal trend, characterized by a steady increase during the early months of the year leading up to a peak in sunshine hours. Starting at 248 hours in January, the region experiences an upward trajectory in daily sunlight that culminates in the month of May, where it reaches 292 hours. This period, extending from January through May, is conducive for outdoor activities and agricultural practices, as the increasing light supports both plant growth and a vibrant ecosystem. Notably, April shows a significant surge with 288 hours, indicating a particularly sun-rich month that often precedes the rainy season.
Conversely, the latter half of the year sees a gradual decline in sunshine hours, with July and August experiencing the lowest levels at 239 hours and 230 hours respectively. This drop reflects the onset of the rainy season when cloud cover often obscures sunlight. However, as October begins, sunshine hours rebound to 252 hours, demonstrating a return to brighter days. By December, the month concludes the year with an impressive 296 hours, making it one of the sunniest months. Overall, Ahafo's sunshine patterns illustrate not only the seasonal shifts of the region but also underscore the interplay between sunlight, agriculture, and daily life throughout the year.
The UV Index in Ahafo, Ghana, indicates a consistently high risk of skin damage due to ultraviolet radiation throughout the year, particularly from January to October, where readings are categorized as extreme. The UV Index peaks in April at 14, suggesting exceptionally high exposure levels that require immediate protective measures. Even during the comparatively lower months of November and December, when the index drops to 10 and 9 respectively, the risk remains very high. Specifically, the burn time remains alarmingly short at 10 minutes across most months, emphasizing the urgent need for sun protection in outdoor activities.
This high UV Index reflects Ahafo’s tropical location, which positions it closer to the equator, resulting in more intense solar radiation throughout the year. As the rainy season transitions from July through September, the index stabilizes and does not remain significantly lower, confirming that outdoor precautions are necessary even during cloudier months. Therefore, residents and visitors must remain vigilant and take appropriate precautions, such as wearing sunscreen, protective clothing, and seeking shade, to safeguard against potential UV-related health risks.
