Forecast for weekend: slightly cooler

NWS still calling for heat index of 103-plus in some areas

Updated 7/31/26: The National Weather Service is forecasting a maximum heat index of at least 103 degrees in parts of Orange County on Friday, Saturday and Monday, with slightly lower temperatures on Sunday. All cooling locations in Orange are expected to be available throughout the weekend — offering air-conditioning or shade, cool water, and various supplies. The heat index is a measure of the air temperature plus the humidity level — typically referred to as the “feels like” temperature.

Lynx, the public bus service, uses the 103 heat index as a threshold to provide free transportation along established routes throughout its service area to anyone asking to go to a cooling location. Homeless drop-in and day-service sites in Orange also use the 103 heat index threshold, while Seminole and Osceola counties use a threshold of 108.

However, regardless of the heat index, county-operated cooling locations — which include libraries, parks and community centers — are available in all three counties during regular business hours to those looking to escape the heat in an air-conditioned or shaded space.

Please note these hot, muggy conditions can be extremely dangerous for people who are unsheltered — and especially those who are elderly or have chronic health conditions — even below the 103 heat index. It is particularly important to stay hydrated and seek intermittent relief from the heat as best you can to allow your body to recuperate. If you suffer dizziness, nausea, headache, severe cramps, extremely hot skin or cool, pale skin, please call 9-1-1 and get medical help immediately. Heatstroke, in which body temperature rises over 104°F, is a medical emergency and can cause confusion, seizures or loss of consciousness.
