UV is not heat
A cooler or cloudier-feeling hour can still have meaningful UV. Use this page for sun-exposure planning and check Miami's heat-index page separately for temperature and humidity burden.
Forecast limitations
Cloud cover, reflection, shade and exact location affect exposure. HeatGuard displays provider forecasts, not a personal UV dose or medical recommendation.
