Update 04.07.18

The nuc hive is growing quickly trough the season. The box is nearly filled with bees, honey combs and brood combs now. As you don't take their honey/food when they're establishing their hive, there won't be any bigger intrusion the next few months except the varroa mite treatment with formic acid in late summer/fall.

This is the last month in data:

It's been very dry and hot lately with lots of rainy/colder days in June. But as you can see the bees do not struggle to keep their hive temperature constant. Only when the outside temp. rises above 35°C (95°F) the hive temperature climbs to around 35.5°C but never reached 36°C yet. Amazing!

Pictures of the hive and bees are coming soon!

Today we checked all hives, including the nuc hives. The bees have been very busy licking out the extracted honey combs (the nuc hives didn't get those combs, only the big, "business hives").
Weather has beex really hot those last two weeks, Temperatures rising to 30°C and above. As usual in Germany you don't get the dry heat, it's always quite humid as well. You can clearly see that in the chart:

Relative humidity got up to 80% at times. As bees don't influence the airs water content directly, they circulate more air in/out of the hive which takes a lot of humidity with it.

This is the recorded data for our city, including total precipitation:
