UV through the year in Luquillo

Near the tropics the sun rides high all year, so UV in Luquillo stays strong across most months and tops out in May, when the estimated clear-sky peak UV index reaches about 13 around solar noon. At that peak the noon sun reaches about 89° above the horizon. Each month below pairs the noon sun elevation with the estimated peak UV and how fast unprotected skin can begin to redden.
