Throughout the year, UV levels fluctuate significantly, with the highest risk occurring from January to March and again in October and November. During these high-risk months, particularly in January and November where the UV Index reaches a peak of 12 (extreme exposure), individuals should be especially cautious, as the burn time is a mere 10 minutes. As temperatures rise, March also demands attention with a UV Index of 7 (high exposure) and a burn time of 25 minutes. In contrast, April to July presents lower UV levels, categorized as moderate to low, allowing for longer exposure times of up to 45 minutes. However, even in these months, it is important to remain vigilant. As August through September roll in, moderate levels return, so keep sunscreen handy. Residents and visitors should always consult the UV Index daily and take protective measures, such as using sunscreen, wearing protective clothing, and seeking shade, especially during the high-risk months.
