That's interesting.I have on odd occasion had wax foundation and comb "slump" in hot sunny conditions, which made a right old mess and took some sorting out. For that reason alone I prefer to site my hives where some shade is present during the middle of the day and into the afternoon. If circumstances don't permit this I create protection from the hot sun with an appropriate sheet of plywood or other thin material. This protection can be as simple as a few blocks of wood set on the hive roof to create a space for air to circulate under the shade sheet which is positioned on the top of the blocks. It's not so important with polyhives as the insulation limits heat absorbtion. As always it's your own decision
How hot was it?
