I don’t know how many people are aware of this, but the Bee Informed Partnership has an interactive map of hive scales. Most are in the US, but there are some in other parts of the world. If you want an idea of what nectar flow is like in your area, and you don’t have a hive scale, you can try to find one the map close to you. Ours is the one in San Diego.
You can even check whether hives within 100 miles of @Red_Hot_Chilipepper agree with him that the flow is over in his area. The only disadvantage is that many hives show on the map, but the data hasn’t been uploaded/downloaded recently.
