Summer heat (Seattle, Sammamish, Rochester: 2014, live in, area)

I feel like I'm melting away in this Portland heat, 90 degrees is ridiculous ☀️

Is Seattle or nearby cities cooler in the summer, or about the same?

Climate-wise, Seattle is usually a few degrees cooler than Portland. Being surrounded by water probably helps. It can get pretty warm in July and August though.

Working in Seattle for the last 12 years, I don't remember having it over 85 more than a handful of times. Here in Sammamish at 600' elevation it may hit 90 2-3 times a year. So far this year it's been 82 twice, otherwise unusually cool, just 49 right now at 7:15am.

If you look at the 10-day weather forecasts for Portland and Seattle, you'll see that Seattle is MUCH cooler currently, than Portland. But your weather is expected to break, and get back down into the 70's this weekend and into next week, OP.

Portland is located far enough inland, that it gets more weather extremes; higher temps in the summer some of the time, and colder winters.However, Seattle has always had high temps in the second half of the summer: late July through August or so.

It reached 85+ 32 times in 2018 alone. It has reached 85+ 125 times between 2014 and 2018 (a 5-year period), so a lot more than a handful of times. Having said that, Portland is usually always warmer in the summer months.

Seattle has the second coldest, least humid summers in the continental USA (SF is #1, PDX is #3).

Warmest summer temps

Phoenix, Arizona 93 34
Las Vegas, Nevada 90 32
Dallas, Texas 85 30
Austin, Texas 84 29
San Antonio, Texas 84 29
Houston, Texas 84 29
Miami, Florida 84 29

Coldest summer temps

San Francisco, California 61 16
Seattle, Washington 65 18
Portland, Oregon 67 19
Rochester, New York 69 20
Buffalo, New York 69 21
San Jose, California 69 21

If you can't handle Seattle (or even PDX) summers, then you are a wimp who will not be able to handle summers anywhere. Zero sympathy. Perhaps the problem is you don't have air conditioning.

Never been to Seattle or Portland. Are they humid in the summer? By the way, I live in the greater Phoenix area and we don't even talk about the heat anymore!

The coldest winter I ever spent was a summer in San Francisco.

No, summers in the PNW are generally quite dry, though the occasional humid day is possible. But “humid” here is nothing like humid in the eastern half of the country.

My brother lives there, and oddly I love visiting him in the summer. The daytime highs on our most blazingly hot days barely touch your nighttime low temps (and are usually ~20 degrees colder). While it's not desert-dry here, we actually get very little rain for the couple months where it gets sorta warm (my AZ friends would be wearing coats in August here), and so the humidity levels are pleasantly low.
