Cooling centers are NOT open at this time.

This weekend is expected to be the warmest of the year so far, with temperatures forecast to reach the 90s on Sunday, May 3.

Because our bodies are not yet acclimated to hot summer weather, which can take two weeks of regular exposure — and even though overnight temperatures will remain relatively cool — early season heat events can pose a greater risk to health impacts. Portland Cinco de Mayo Fiesta attendees are especially encouraged to be mindful of heat safety as they enjoy the event outside under the sun.

It's important to take precautions like hydrating, scheduling outdoor exercise or yardwork for the cooler hours, and making a plan to spend time somewhere cool. Heat stroke is a life-threatening emergency. If you see symptoms in yourself or someone around you, call 911 and seek immediate medical care. 

Check this interactive map of library branches, pools, community centers and other cooling spaces, and make a plan to cool off when it’s hot. Always confirm hours and locations of libraries before you go. Remember that several libraries are closed for construction. Bookmark this webpage (multco.us/hot) for the latest updates on cooling centers and other resources to stay safe on hot days. 

If you plan to seek relief from the heat in waterways, please swim and splash safely. Hot temperatures combined with cold, early-season snowmelt can be dangerous in lakes, rivers and creeks. Even for experienced swimmers, these conditions can lead to shock and drowning. Be aware of swift currents, cool water temperatures, hidden hazards and uneven bottom surfaces.

Take steps to stay cool and safe as we approach summer 

Now is the time to prepare yourself and get your home summer-ready before it gets too hot. Stock up on fans/air conditioners and sun-blocking curtains, sunscreen, and other summer essentials. Installing home cooling can take time, so make arrangements now. Call 311 to check your eligibility for free air conditioning, and check with your utility to learn about assistance with energy bills. 

Community members are advised to take care when working or playing outside in the midday heat. People attending outdoor events under the sun, as well as those without indoor cooling, are especially encouraged to be mindful of heat safety. 

County staff have been working with property managers across the community, providing tips, resources and education about heat preparation, the health impacts of heat and energy efficiency programs. 

Certain groups most at risk of heat-related illness

Now is also a time to make a plan for pets, children, adults 50+, 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 new outdoor recreational activities (especially children on turf fields)
  • People who have consumed alcohol

Support our community

Interested in supporting our community during future heat events? Prepare now to help out as an emergency shelter volunteer if Multnomah County opens cooling centers or shelters (Disaster Resource Centers) and requests help from community volunteers.

Consider hosting a misting station. Or work with the Office of Emergency Management to create a Disaster Resource Center.
