Perform an inspection for capped swarm cells. It is not uncommon to see uncapped queen cell this don’t necessarily mean they are on the verge of swarming. With strong populations during hot weather many bees will hang outside the box to help control temperature in the hive. Like when I was a kid during hot weather mother would kick us out of the house to cool it off.
If you find a lot of capped swarm cells swarm prevention is in order, splitting is the best way to head off a swarm. You can always recombine later in the season when the swarm season is over.
