No 80° weather here, nor 60° nights,
@MoonShadows ...
Climate is often uniquely local, especially in places with great elevation differences. It's a little mind-boggling but a hardiness zone map of Colorado demonstrates the idea.
My own gardening geography experiences are limited. I moved here many years ago after a few gardening seasons on the coast of northern California. After experiencing those cool summers, I thought that I'd be getting into some real growing season heat, moving so many miles inland from the Pacific.
In a way, yes but one needs to look at daily averages and the cool summer nights lowered the numbers. Seasonally, our cool springs undercut the entire growing season. When it came right down to it, I didn't move where there was any more seasonal warmth than when I could walk out in my front yard and see the waters of the Pacific ocean!
What is more ... accumulated seasonal warmth doesn't add up to any more than some of the coldest winter areas in the US.
I finally began to figure that out from US Weather Service data on growing degree days (
link). It's not so great to be behind Fargo North Dakota already this year ! You can see the numbers for Spokane, my nearest weather station accounting for growing degree days. Now, look at Fargo ...
I have this little game keeping track of not Fargo but Devils Lake North Dakota. I've been able to correspond a little with a gardener near Devils Lake. She is frustrated by wind and freezing weather. She hopes to be able to plant peas and potatoes soon.
This probably isn't a real surprise to anyone. And, I'm not going to upset her by saying some of my potatoes were planted more than a month ago. What will be surprising to some is that when the growing season comes to an end, her garden may well have experienced more accumulated warmth than mine.
Well, the West was generally a fairly hot place last summer. We had a winter here that someone in North Dakota can only dream about. Everyone hopes we don't burn up this summer ...
Every location has it's challenges. I'm not sure how many gardeners would appreciate all the heat some place like Blythe California has
already experienced in the last few months.
