I live in ZIP code 98204, just 2 miles from Puget Sound. I only grew tomatoes one year.
A "warm summer day" goes over 75. A "hot summer day" goes over 80F.
Nights almost always go back down under 70 or 65F.
That's just my recollection, not based on checking records.
Sungold cherry tomatoes: ripened and were sweet for 4-6 weeks.
Stupice: ripened but caught a chill after a few weeks and then had no sweetness.
(?Sweet Million?) The plants did not thrive and disappeared before having a chance to ripen. Maybe I planted them too close to the Stupice which shaded them, then choked them.)
>> cultivar name, transplant date, first harvest date, and zip code.
Sorry, I didn't record either date.
All three I bought as seedlings before nights stayed over 50F. I potted them up and then carried them indoors every night for weeks. I planted them out once nights stayed over 50, but nights got cool again pretty early in the Stupice harvest season. Maybe I should have put them in the ground sooner, figuring that the bigger root zone would help more than the cool night would hurt.
