It's a local thing mostly, though the drought isn't helping. It all depends on the flowers and temperatures, and we are mostly dependent on blackberries for ours. I've talked with some in the midwest, and they saying they have had a record honey year.
We initially got the bees for pollination, not honey, so the honey is just a bonus. With all the work you go through to harvest the honey, you just want enough to make it worth the work.
My MIL has a HUGE tulip poplar tree and they are supposed to be fantastic for nectar, so I'm thinking of putting a hive at her place in the spring.
Yes local conditions affect a lot. We had a REALLY wet spring, which greatly affected our honey crop, too- not enough clear sunny days for the bees to collect nectar! It's a fine line between too much rain and too little rain to get a bumper crop of honey! But the wet year (and subsequent summer and fall rains more than normal) means we will get a fall crop of honey here in NE Oklahoma! Wish we could have sent some of our rain your way!
