Throughout the year, the UV Index exhibits significant seasonal variations, peaking in the summer months. January starts with a UV Index of 10 (very high), but by February, it rises sharply to 12 (extreme), and continues to escalate until it reaches its maximum in July at 15 (extreme). This elevated threat persists through August, dropping only slightly to 14 in September and back down to 12 in October.
