Plants look healthy, lots of blooms, but very little fruit.

It could have been weather, but typically when you have an across the board crop failure like that, some element is missing from the soil. I would strongly recommend taking a soil sample to the local extension service and having them test it. A severe micro nutrient deficiency (of which it could be many and only a soil test will tell) could cause this to happen. It could also be too much nitrogen in the soil or a lack of pollinators in the area.
