Huge beard on the front of the hive every evening — normal in this heat or are they about to leave?

Second year, two hives near İzmir. Every evening around sunset both hives have a thick curtain of bees hanging off the landing board and up the front — last night it was maybe the size of two hands stacked, just a quiet mass of bees breathing. Daytime temps have been 36-38C all week. Inside the hives everything looked normal at Sunday's check: queen laying (less than June, but laying), stores okay, no queen cells. My neighbour who had bees years ago told me bearding means they're preparing to abscond and I should 'close them in at night'. That sounds wrong to me but now I'm second-guessing. Is evening bearding in a heatwave just… air conditioning? When would bearding actually be a warning sign?

Your instinct is right and your neighbour is wrong. Bearding in a heatwave is thermoregulation — bees move OUT so the brood nest stays at 34-35C without their body heat adding to it. Andalusian hives wear beards all of August. Absconding looks nothing like this: it's the whole colony gone in an afternoon, usually after severe stress like starvation or constant robbing. Never close them in on a hot night, that can actually cook the colony.

Same picture in Alentejo right now. Things that help: shade (even a propped board over the lid), a water source nearby, and don't restrict the entrance more than defense requires. Some run a small upper vent in extreme heat. The beard is the bees solving the problem — your job is just not to make it harder.

Thank you both, big relief. I put a shade board over each hive today and topped up the water tray with cork floats. Beard tonight already looked a bit smaller. I will politely ignore the neighbour from now on.
