From January to February, the UV Index is moderate at 4-5, with a burn time of about 30 minutes. However, by March, it escalates to 8 (very high), and remains at 9 in April. The peak risk occurs during the summer months of May through August, where the UV Index reaches a concerning 11 (extreme) with a burn time of just 10 minutes.
