Visitors and residents should exercise caution during these months, as the potential for sunburn increases drastically, with burn times as short as 10 minutes. As spring approaches, UV levels remain elevated in March and October (very high category with burn times of 15 minutes) before dipping to moderate levels in April and May with burn times extending to 30 minutes.
