Overall, lavenders blooms from mid-june to the end of August. So don't sweat it, you should be in the good period for most places ! This year's rains should delay the crops a little bit. In doubt, try to call the tourist office of the places that caught your eye :)
Here's a quick translation of that page which suggests 6 itineraries to see lavender fields (I left the itinerary titles in French so you can find them easily on the page):

I completely agree with Boris answer - this is my most favorite area of France (I live in Paris).
If this helps, I wrote a personal review of the village located close to the lavender fields in Provence: Moustiers-Saint-Marie.
My husband and I travel very frugally and found this village lovely. There's a stigma that Provence can be expensive, but we found it lovely and super romantic.
Please let me know if you have been here before. Hope my words do it justice:

I think this a bit opinion based, but the best place would be in the Verdon, just above the Lac de Ste Croix, on the road called "Route de Moustiers", because you can visit the little villages (Moustiers Ste Marie), and of course the Gorges du Verdon.
But it really depends on where you plan to stay, because Provence is big.
