Joanne,
About "average" temps in spring. Here, I picked March 25. Our average high is 56°F and average low is 32°F. But as I said before it varies a lot from year to year.
I keep hearing that we're getting all this extremely cold weather and snow this year due to an El Nino. I'm wondering if those patterns were already in place last summer? Our weather was so cool, cloudy, and rainy last spring and early summer, it was a challenging summer for gardeners. Were these ocean patterns already in place then?
