I was wondering. My hives are on my roof. full sun most of the day from early morning to late afternoon. Roof being tarred Zinc.
Temperature in the shade in the garden is back to 27+ deg C. I do not dare putting a thermometer up there…
Can it become too hot for the bees ? shall I install a shade system somehow to reduce direct sun impact on the hive ? I did that last year with a kids sun umbrella and worked it seems. But now with 2 hives, it would look like a private beach on the French Riviera up there.
