One important factor is the temperature during bloom time and somewhat 
after.  We had a very warm spring this year and not only are my grapes 
more than three weeks early, they are much larger than usual.  This 
isn't just my observation, either.  Temperate Zone Pomology by M.N. 
Westwood says the same thing - warm weather at and just after bloom 
time allows the developing fruit to have more cell divisions, which can 
give bigger fruit.  Cool weather means fewer cell divisions in the 
ovary (the developing fruit) so there are fewer cells to enlarge during 
ripening phase, and thus a smaller fruit.
	I'd bet that tree fruits in the area are smaller than usual too, 
unless there was a really light crop to allow the tree to throw more 
energy into the remaining fruits.
