Throughout the year, the UV Index experiences significant fluctuations, peaking during the summer months. January and February show moderate levels of UV exposure (Index 3-4), with a burn time of 30 minutes, suggesting that while sun safety is recommended, the risk is lower. However, from March onward, the risk increases notably, reaching a high index of 6 in March and escalating to very high levels (Index 9) in April and May, where burn times drop to just 15 minutes. The summer months of June, July, and August present extreme conditions, with an Index of 11 and a mere 10-minute burn time, marking these as high-risk months. As temperatures begin to cool in September, the Index remains high at 10 before decreasing in October to 7 and returning to moderate levels by November and December. Residents and visitors should exercise heightened caution and employ sun protection measures during the spring and summer months, particularly when the UV Index exceeds 6, to prevent harmful sun exposure.
