Depends on how early the trees blossom. In this area the damson crop is excellent as blossom time coincided with the mild spell mid-Spring, which also gave an early boost to the nectar available to local bees. . Most of our neighbours with apple trees found blossom time coincided with the following colder, wet weather and have a very poor, or non-existent, crop. Our own trees are old, unidentified local varieties but they blossomed late and are laden.
