This summer has been cool and most of my tomatoes are just starting to ripen. Black Krim, a mid-late season, was actually the first to ripen and is still producing whereas early-mids (Rutgers and Grandma Mary's) planted the same time right next to them are just starting.

First question - when did you put out the transplants?

Lots of people north of the mason dixie line are having delays with early varieties this year. Here in Oregon I contribute much of it to very cool nights even though day temps have been warm to hot.
Even my early varieties are starting to ripen pretty good except for my Bush Beafsteak Det plant. It is rated as 62 days to maturity and not a single tomato is even beginning to ripen. It has several tomatoes on the plant but they are all green. Oh I transplanted it 90 days ago and have harvested several Brandywine and other long season varieties a few weeks ago.

Gregory,

You are right on the money about night lows.
Here in North Seattle area(Sammamish) our night lows RARELY stayed above 58F. Even when day highs were like 87F, the temps doped to under 60F. This is because of our very clear skies and low humidity. Now we are in double jeopardy. The day temperatures are going down as well.
My plants are loaded but ripening is getting VERY SLOW.
