Heat Safety Tips from NWS Seattle

A record-breaking heat wave is unfolding across the Pacific Northwest with many heat records already forecast to be broken. The heat wave is expected to last through the weekend and into early next week.

On top of this, Seattle and surrounding areas are one of the least-air-conditioned metropolitan areas in the U.S., adding to the dangers posed by this excessive heat. As such, it may be prudent to review some of the steps that can be taken to remain cool in the face of oppressive heat.

  • Let the cool night air in. Open the windows right before you go to bed, but make sure to close the windows before it starts to heat up again.
  • Keep your blinds closed. Using dark-colored blinds is even more effective, as it can block sunlight and unwanted heat from entering. Investing in blackout curtains is a good option, if possible.
  • Use fans. Set your ceiling fans to rotate counterclockwise and set a bowl of ice water in front of large standing fans to create a cool, misty breeze.
  • Cook outdoors. Avoid using the oven or stove if you can, as they will make your house hotter. An outdoor grill, however, will not.
  • Sleep low. Remember, heat rises, so sleeping in the lowest floor available can help. If that isn’t an option, moving mattresses to the ground instead of on the bedframe may help.
  • Stay in a cool place. Cooling centers have already been opened in Seattle; check with local authorities to see cooling center statuses nearby.
  • Consider cancelling outdoor activities. Staying inside during the hottest parts of the day is a must during extreme heat.
Excessive Heat Warnings and Heat Advisories are already in place across the Pacific Northwest. It cannot be stressed enough that this heat wave is record breaking and extremely dangerous. Heat sickness is a real disease, and heat strokes can be fatal. Be sure to comply with local regulations if issued.

If you cannot avoid being outdoors, especially during peak heating from late morning to early evening, make sure to drink plenty of fluids to stay well-hydrated. Wear lightweight and loose-fitting clothing and make sure to check on those most vulnerable; the elderly, children, and pets.
