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. The high-risk months for UV exposure are February through September, where the UV Index consistently stays at 12 or above. Residents and visitors are strongly advised to take precautions during these periods, including wearing sunscreen, protective clothing, and limiting sun exposure to avoid skin damage, especially during peak hours when burn time can be as little as 10 minutes. As winter approaches, UV levels decrease, but it's still vital to maintain sun safety practices in November and December, where the UV Index is 10 and 9, respectively.
