According to the gauge in my car the outside temp in the sun was about 20c
One of my outside hives is unbelievably busy flying about,from quite early in the morning as is the observation hive, but the bees from the other outside hive are very conspicuous by thier absence.... I am tempted to open the hive and see if all is ok but also feel that it might not be a good idea.
At about mid day for 30 mins the sun shines directly onto both hives and only then does the flying activity from the non active hive increase for a bit.
Fair bit if orange pollen coming in.
