Good question. After a little research all I can find is the word, "temperature." With soil temps getting higher I would guess there is a temperature sink right around the pots and even the air temperature at the pot is higher than away from the pot.

There are several reasons for blossom drop besides air temperature. Stress is another main reason. Root stress probably adds to blossom drop problems. Do you have a thick mulch on the surface of the pot or is it bare soil? That may help keep soil temp down. Shade cloth may also help.

I think you have found the reason for blossom drop but now you just have to find a solution. The two I have mentioned could be a good start. Moving the pots to a better location if possible may be another solution. I am sure there will be more suggestions.
