Dozens of cool spaces are open in Multnomah County today.
Cool spaces, including dedicated cooling centers, are just one part of Multnomah County’s response to heat, designed to support people when heat risks become extreme.
Bookmark this webpage (multco.us/hot) for the latest updates on cooling centers and other resources to stay safe on hot days. You can also check this interactive Multnomah County map showing dozens of cool spaces like library branches, community centers, interactive fountains, pools and splash pads.
Multnomah County Libraries are open regular hours; always confirm hours and locations before you go. Remember that some libraries are closed for construction.
Take steps to stay safe in the heat
Community members are advised to take care when working or playing outside in the midday heat. Remember to drink more water and take cooling breaks. People attending outdoor events under the sun, as well as those without indoor cooling, are especially encouraged to be mindful of heat safety the next few days. If you have access to air conditioning, consider keeping your home around 78 degrees F. Check with utility companies to learn about assistance with energy bills.
Check in on your neighbors, friends and relatives and make a plan for visiting a cool location, even for a few hours.
Learn about the symptoms of heat illness and how to respond. This information and printable materials are available in English, Spanish (español), Vietnamese (Tiếng Việt), Russian (Русский), Chinese (中文), Arabic (العربية), Somali (Soomaali) and Ukrainian (Українська).
If you plan to seek relief from the heat in waterways, please swim and splash safely. Be aware of swift currents, cold water temperatures, hidden hazards and uneven bottom surfaces.
Heat worsens air pollution
Elevated heat worsens air pollution, causing air pollution to accumulate and create ground-level ozone (also known as smog). To protect public health, the Health Department is issuing a mandatory wood burning restriction for residents in Multnomah County. The restriction comes alongside the Multnomah County Fire Defense Board-issued burn bans for fire safety since June 15, 2026.
The Health Department’s burn restriction goes into effect at noon July 21, and will be lifted when conditions improve. Recreational fires, agricultural burning and backyard burning are not allowed. These restrictions do not apply to cooking, but residents are encouraged to stay alert and use caution. If you are experiencing symptoms such as difficulty breathing or worsened asthma symptoms, use your inhalers as directed and contact your health care provider.
Health officials emphasize that managing extreme heat remains the top priority, as overheating is more dangerous than smoke exposure for most vulnerable individuals. There are actions you can take to protect yourself and your family from heat and smoke. Residents should check air quality before opening doors or windows and adjust or limit outdoor activities. Cool, clean indoor air is the best way to protect yourself. For more tips, visit multco.us/smoke.
Certain groups more at risk of heat-related illness
Now is the time to make a plan for pets, children, adults 50 years or older, and those with medical conditions, all of whom are more vulnerable to heat illness. Those facing the highest risk of heat-related illness include:
- Men over 50 who live alone
- People without access to air conditioning
- Pregnant people
- People on certain medications
- People who work in hot indoor or outdoor environments
- People engaging in strenuous or outdoor recreational activities (especially children on turf fields)
- People who have consumed alcohol
Worker safety
People who work outside are encouraged to drink plenty of water and take breaks in the shade. Under Oregon Occupational Safety and Health (Oregon OSHA) rules, outdoor workers are entitled to shade, breaks and water. Employers are responsible to protect their workers. Oregon OSHA has more information for workers about their rights under state law.
Know your rights during extreme heat events
State rules protect against electricity service disconnections during extreme heat. This means Portland General Electric (PGE) and Pacific Power cannot disconnect you the day before a severe heat alert, during the alert and for 48 hours after the alert ends.
Severe heat alerts include Heat Advisories, Extreme Heat Watches and Extreme Heat Warnings. Learn more about your protections and how to contact your provider if your power is disconnected.
