The UV Index demonstrates significant seasonal variation, peaking between March and June when it reaches extreme levels (11-12), indicating a high risk of harm from unprotected sun exposure. The highest risk months are March, April, May, and June, where the burn time drops to just 10 minutes. Visitors and residents are strongly advised to take precautions during these months, such as wearing sunscreen with a high SPF, donning protective clothing, and seeking shade during peak hours. As summer progresses into July and August, while the index slightly decreases to 10-11, caution is still warranted. September and October maintain a very high exposure category, so continued vigilance is essential. As winter approaches in January and February, the UV levels drop to high and very high, respectively, but precaution is still advisable given the potential for swift sunburns. Overall, throughout the year, staying informed about the UV Index and taking protective measures is critical for skin health.
