Throughout the year, UV Index levels display significant seasonal variations, with notable peaks during the spring and summer months. From March to August, the UV Index reaches extreme levels (11-13), indicating a high risk of harm from unprotected sun exposure, with an exceptionally short burn time of just 10 minutes during these months. The highest UV Index occurs in May through July, where protective measures are crucial.
