Tomatoes won't turn?!

[Brindle]

So I have this yellow pear heirloom cherry tomatoes plant that is huge (see pic), with tons of tomatoes on it.....problem is, not one has turned yellow! I don't get it. When I planted this variety at my old house they would ripen way faster. Any thoughts. I'm in San diego.

Sorry for the typos!

What are your night-time temps there? (We had a similar post recently, but it must have been on a non-tomato sub-forum, as I couldn't find it). High night temps keep many tomatoes from ripening. One year, I had a period of time when we did not get lower than the 80s at night, and I did not get a single ripe tomato until the lows dropped into the 70s.

It hasn't been warm at all. Nice cool nights. Weird. I've never seen this before
