I am not in New England but the climate is somewhat similar here.
It would be much better if the seed companies would switch from days-to-maturity to information on growing conditions. The Weather Service keeps track of "growing degree days" for us and commercial sweet corn varieties (for example) are sold with that information on the tags.
It seems that 1700 growing degree days is something of a rule of thumb for ripe beefsteak tomatoes. The Weather Service shows that Burlington, VT; Concord, NH; & Worcester, MA are now in the ballpark (click)
. Maine might have to wait a few more days.
In my garden, I'm still waiting to get a little closer to 1700 GDD but have had dribs and drabs of cherry tomatoes for a few weeks now. Only the very earliest of the heirlooms have produced a ripe fruit and the plants are so small that I can't expect much from any of those.
That lighter green on many of those tomatoes looks promising to me, Filmnet. A couple more days of warm sunshine and you should be in the ripe tomato business
