Heat index
Open NWS heat safety. The heat index combines air temperature and humidity. Central Florida summer afternoons often sit in the band NWS marks as extra caution. The page lists signs of heat illness and the order: water, shade, rest.
When to walk
Early morning and evening are the usual city-loop hours when the index is high. Lake Eola, Bill Frederick Park, and the Cady Way Trail publish their own hours. Confirm the start time on the park page.
