As an average it takes about 27 degrees F or less to kill the blooms/ fruit 
in Apricots. The exact temperature depends on what stage the blooms/fruit 
are in. The lenght of time at the 27 degrees can be as little as an hour. 
The longer the time the more that will be killed. Sometimes even if it gets 
to 27 there may be a few buds that have not opened or some protected fruit 
that come through. At 25 degrees F you can forget the crop.

Maybe the weather will cooperate this year.
