Jim you are correct.
It seems there is always something coming in without having large "flows". It builds before the wet (monsoonal weather) and again after the rain. The bees slow through winter but dont actually stop foraging- no frost.
For me i have found that the wet this year was tricky. I had one hive swarm (second season hive and queen) and i split another (firt season hive and queen) as it produced swarm cells. It seems they built up well and then are confined during the wet as the forages are also in the hive, although they still forage a little even in the rain. I believe this "forced" crowding triggers them, but hay im only guessing. Lots of young bees and brood.
During the rain its almost impossible to inspect, hence cells when you do get that hour of opportunity. The swarm shot off after 3 weeks of rain on the first opportunity...i was home and they left prior to my planned inspection that day-doh! Hanging from the tallest tree off the top branch some 30 + meters high!!
Im running one full deep for brood with excluder and one full super...skim off when i can to provide room.
I am strongly considering 2 brood boxes with one super next year to give me more time. ...very open to suggestions.
