Throughout the year, the UV Index displays significant seasonal fluctuations that warrant attention from both visitors and residents. From January (UV Index 4, moderate exposure) to February (UV Index 6, high exposure), there is a notable increase in ultraviolet radiation, leading to higher sunburn risk. The months of March through June represent high-risk periods, with UV Index values peaking at 11 in June (extreme exposure) and maintaining levels above 8 until September. During this summer surge, burn times can dwindle to as little as 10 minutes in June. September to October shows a slight decrease, though values remain high (UV Index 9-8). Following this, November and December return to more moderate levels (UV Index 5 and 3), allowing for longer exposure times without an immediate burn risk. It is advisable for everyone to stay vigilant during the high-risk months, particularly from March to September, and to employ protective measures such as wearing sunscreen and protective clothing, especially during peak hours.
