Hi, I endorse all @Dawn_SD has posted.
has a lot of good stuff on this subject. Just need to wade through it or go to the search box, top right corner, “ventilation Perth”
While not getting to those temps that Perth experiences, in Busso like Perth ventilation becomes more of a problem in Winter than Summer. Our dry heat is easily handled by the bees by fanning and if that is not working the hive sends bees outside to “hang around” (bearding) till it cools down.
The humid and wet conditions in Winter can cause condensation to the point of flooding the hive if not corrected. For help on the search “condensation”
