PNW weather
We came from Northern California where it was over 100 degrees for 4 to 5 months of summer. We are now living the evergreen state instead of desert. Refreshing is an understatement! But It was the 4 months of fires and tremendous smoke that drove us out.
Weather in Washington
We moved to the east part of the state and find little rain this side.Do get some snow but not too much.Very pretty here.
Cool Weather Makes It More Livable
People have lost their sense of perspective for the last couple of decades. There was a time when there was only a couple of months of warm weather and no one had air conditioning at all. I see the weather at 72 degrees with everyone having their car windows rolled up with the climate control on releasing additional hydrocarbons in the air. Spring and summer is for driving the country roads with the windows rolled down. The cooler weather is great for woodwork building custom kitchen cabinets or a new dining room table. Why go to a country fair when it’s so darn hot?? You ever try to build an old hot rod pickup on a hot day?? Then when everything is green.....to include your yard, the plants pull more carbon out of the air. The weather now is allot more warm than it was decades ago when the Columbia River froze hard and people drove on it to Portland. There was allot more flooding too....
2020 PNW Summer
I never understand why people are surprised when we get a cooler summer! It's Western Oregon/PNW -- totally normal weather. I love it! Keeps our forests green and lush. Looking forward to cozy autumn and maybe some snow this winter? Fingers crossed!
