Up until this week, there have been only 13 days on record that temperatures in Seattle have remained 67 or higher overnight — but that’s about to change.

The excessive heat we’re braced for will do more than warm up our days, according to meteorologist Dana Felton of the National Weather Service’s Seattle office.

“It’s going to be warm at night,” he said.

Felton said the overnight temperatures have remained at 67 or above only 13 times in the past 73 years since official temperatures have been recorded at Seattle-Tacoma International Airport.

Tips for hot weather

    • Drink plenty of water to stay hydrated.
    • Never leave children or pets unattended in cars.
    • Apply sunscreen if you are going to be outdoors.
    • Stay inside in air-conditioned areas if you are more susceptible to heat.

This week, however, overnight lows are expected to remain relatively high all week with daytime highs predicted at 94 on Wednesday, 99 on Thursday and 95 on Friday. The overnight lows are forecast to be 66 degrees on Wednesday, 68 on Thursday and 67 on Friday.

With that in mind, here are a few tips (from wonderhowto.com and other websites) for sleeping cooler:

  1. Make a batch of mint tea without sweetener. Put it in the fridge and then into a mister. Use it to spray down your face and body.
  2. Put your sheets and pillowcase into the freezer for a few hours, then make the bed with them.
  3. Put a couple of bottles of frozen water, or a bowl of ice water, in front of the fan that’s aimed at your bed.
  4. Grab some gel ice packs, freeze them, then put them in a pillowcase and place at strategic points — under your neck, knees, wrists.
  5. Turn off and unplug every electrical appliance you can.
