Visitors to Walt Disney World and Universal Orlando Resort faced dangerous conditions Monday as an Orlando heat advisory remained in effect across parts of Central Florida. Forecasters warned that high humidity would push heat index values, often called “feels-like” temperatures, as high as 109 degrees.
The National Weather Service issued the advisory from 11 a.m. until 8 p.m. on July 27. It covered Orange, Lake, Seminole, Volusia, and northern Brevard counties. Universal Orlando Resort is located in Orange County. Most of Walt Disney World is also located there, although part of the resort extends into Osceola County.
Afternoon temperatures were expected to reach the low to mid-90s. High humidity, however, was forecast to make conditions feel much hotter. Meteorologists said the heat index could range from 105 to 109 degrees.
Heat and Humidity Increased Health Risks
The Orlando heat advisory reflected another day of intense summer weather across the region. Hot temperatures and high humidity have combined several times this season to create hazardous outdoor conditions.

The National Weather Service warned that prolonged exposure to extreme heat can increase the risk of heat-related illnesses. Officials urged residents and visitors to drink water regularly throughout the day. They also recommended spending time in air-conditioned buildings whenever possible.
People who needed to be outdoors were encouraged to wear lightweight, loose-fitting clothing. Officials also advised limiting strenuous activity during the hottest part of the afternoon. For our list of how to stay cool at the parks, check out this article.
Health experts remind people to recognize the warning signs of heat-related illness. Heat exhaustion may cause heavy sweating, weakness, dizziness, nausea, or headaches. Heat stroke is a medical emergency. It can cause confusion, loss of consciousness, or a body temperature above 103 degrees.
Families with small children and infants should be especially careful as they can overheat more easily. Take advantage of the baby care centers at all of the Disney and Universal parks for a chance to cool off inside.

The National Weather Service also warned against leaving children or pets inside parked vehicles. Vehicle interiors can heat up quickly, even when outdoor temperatures are lower than the heat index.
Storm Chances Remained in the Forecast
Forecasters also expected isolated to scattered afternoon showers and thunderstorms. Rain can briefly lower temperatures, but storms may also produce dangerous lightning and heavy downpours.

Central Florida’s summer climate often combines high temperatures with elevated humidity. Those conditions can produce heat index values well above the actual air temperature. The heat index measures how hot it feels by combining air temperature with relative humidity.
Theme Park Visitors Faced Extreme Heat
Many guests at Walt Disney World and Universal Orlando Resort spend several hours outdoors. They also walk long distances and wait in outdoor queues. Those activities can increase heat exposure during advisory conditions. Visitors can reduce their risk by staying hydrated, taking breaks indoors or in shaded areas, and monitoring weather updates throughout the day.
The National Weather Service uses Heat Advisories to alert the public when heat and humidity reach levels that may pose health risks. Officials encourage people to monitor local forecasts because weather conditions can change quickly during the summer.
The Orlando heat advisory remained in effect until 8 p.m. Monday while forecasters continued to monitor conditions across east-central Florida.
