The heat index — often referred to as what the temperature “feels like” — combines air temperature and humidity. According to the National Weather Service, prolonged exposure to a heat index of 103 degrees or higher can lead to serious health risks, including heat exhaustion and heat stroke.
While the new threshold may sound like a significant operational shift, County officials emphasize that cooling locations are already open and available regardless of temperature.
“There’s a common misconception that cooling locations only open when we hit a certain number,” said Carlos Durden, Assistant Manager, Office of Emergency Management. “In reality, these places are always available during normal business hours for anyone who needs relief from the heat.”
These cooling locations include air-conditioned public spaces and recreational water features designed to help residents stay safe. Options range from Orange County Parks and Recreation facilities and splash pads to library branches, community centers, and local homeless shelters.
What changes at 103 degrees?
When the heat index reaches 103 degrees, LYNX will begin offering free bus rides to and from any designated cooling location, removing transportation barriers for those most vulnerable to extreme heat. That means whether you need a break from the heat for an hour or a safe place to spend part of the day, getting there becomes easier and more accessible.
Officials stress that residents do not need to wait for a heat advisory to take advantage of these resources.
