Huge beard on the front of my hive tonight — photo attached, should I be doing something?

First year, one hive, Minnesota. It hit 34C here today with awful humidity and when I got home from work there was a beard of bees the size of a dinner plate hanging off the landing board and up the front of the box. Photo attached. They're just... hanging there, fanning. Inside checkup on Saturday looked fine — queen laying, they're working on the second deep, no swarm cells. Is bearding a sign they're about to swarm, or too hot, or too crowded? Do I need to add a box or vent something tonight? First time seeing this and my stomach dropped.

Relax — that's a healthy colony air-conditioning itself. On hot humid nights the house bees that aren't needed inside move out so the fanning crew can circulate air and evaporate nectar. Bearding is calm bees hanging in curtains; a swarm is a roaring tornado at 11am. You checked for swarm cells Saturday, so you're fine.

Agree it's normal, but you can make their job easier. I slide a popsicle stick under each corner of the outer cover in July — that top gap lets the hot moist air out instead of forcing every bit of it back through the entrance. Some people give a small upper entrance instead. Either way the beard usually shrinks noticeably.

I will gently disagree with adding vents everywhere. Bees regulate airflow themselves with fanning stations, and research on hive thermodynamics suggests extra openings can force them to work harder to control humidity, not less — nectar curing needs that airflow managed by the bees. A shaded hive and a nearby water source do more good than holes. Bearding costs the colony nothing.

Second year here and I panicked over the exact same thing last July! Mine bearded every hot evening through August and went into winter strong. The thing that actually helped was afternoon shade — I put a scrap of plywood over the cover angled against the sun. And make sure they have water closer than the neighbour's pool.
