Yes sir, a specific area that is vulnerable to wild fluctuations isn't the right spot for readings that are the "official" ones.
Rehoboth Avenue, the "main drag" that leads through the heart of Rehoboth from Coastal Highway to the Boardwalk is probably only a couple of miles in length. A few years ago for our summer vacation my car was reading 95 leaving the highway. By the time we got to our ocean block home, it was 84. At any rate, I think (?) the official reading for OCMD is at the airport in West Ocean City...same kind of deal, I'm sure. It's probably mid 90s at the airport often while along the boards it's at least 10-15 degrees cooler.
