Slow To Ripen?

Is it me or are the tomatoes very slow to ripen? I have been  dry excited to see the bunches of fat juicy looking toms on the vine, mouth watering ready to pic. But hold on! they are not turning ………..

 

I have been told that I am not the only one having this issue? I thought that with all the nice weather we would be having our own La Tomatina!!! 

 

Tomatoes a plenty but slow to ripen
