I wish there were some easy statistics for comparing summer warmth, as there is for winter cold. I kep a degree-day calculator link in my sig block.
Very probably, your spring and fall crops are my summer crops.
YOUR summer crops might need more heat than I have.
For me, tomatoes other than some cherries are a challenge. Even 'Stupice', a small cold-weather tomato was only tasty for a few weeks. then a few cold nights made them taste like cardboard or oatmeal.

Yup. Garden threads by Texans drive me crazy. We're both "Zone 8", but their spring crop of tomatoes is ripe and then over due to summer heat before I have nights that usually stay above 50 F. Their first crop of tomatoes stops flowering due to early summer heat while I'm still carrying trays back indoors at night to keep them warm!
