Make sure your bees have a source of good water during this hot dry weather--I use a bird bath near the hives. You might consider propping your hive tops open to help the bees stay a bit cooler--don't leave them open when the weather cools.
We are in the midst of a major honey flow. Keep an eye on your honey supers adding as necessary. I usually put the new super under the one that is about 2/3 full.
