Given the cool wet weather I would imagine that anyplace will be about 2 weeks behind in their schedule. I use this site to get up to date info about pick your own farms. It literally can be day to day. NH has listings, but didn't see any real close to Center Harbor. My hanging pots will be yielding about a quart every 2 weeks in about 2 more weeks here in CT. Using a bloom spray helps alot.
