Weather forecast for Portland, Oregon for Tuesday, June 21, 2022

PORTLAND, Ore. (KOIN) — Right on cue with a warm-up this week, summer is here.

The summer solstice, a time when the north pole is tilted most directly toward the sun, was official at 2:14 a.m. Tuesday.

Ready for the whiplash? Temperatures will approach 90 degrees this weekend, with the possibility of being as hot as 95 by Sunday. Our hottest day so far this year was 81 degrees earlier this month. The majority of June days so far have included below normal temperatures and rain.

Little reminder that the normal climatic end of June for Portland is 75 degrees.

This time last year it was 93 degrees. This afternoon we expect late afternoon highs to reach 80 degrees. We’ll start with morning clouds, dissipating in the afternoon. If we hit 80 degrees, it will be the second day over 80 degrees this year.

Forecast models indicate a warming of more than 10 degrees by this weekend. Assuming all goes according to plan, Saturday would be the first 90 degree temperature for us this year.

Weekend warriors, beware. How are you going to prepare for this quick warm-up? We won’t break any records and it will probably only last until Monday. However, the unusually cool spring we’ve had will make this warming up to the 90s feel like an oven by comparison. The last time Portland had temperatures in the 90s was August 15, 2021 with temperatures of 94 degrees.

Think fresh water and a fan, but whatever you do, don’t be tempted to swim in our rivers with fresh melting snow. The water temperature is still cold enough to cause hypothermia.

Have you ever heard of a fake sunset? I took a screenshot at 9:12 p.m. Monday night on the Riverview Bank cam. Is the sun still up at 9:12 p.m.? No. He goes to bed at 9:03 p.m.

Here, the sun is actually below the horizon, but the light is playing tricks on your eyes. Sunlight is refracted when it hits our atmosphere and bends towards us. That’s why you get the illusion of a sunset later.
