Brad, I'm in what is one of the more mild regions of MA that is not Cape Cod or the Islands. My house is located ~100 yards from the ocean, which plays a very significant role in moderating our temps. We generally slide into winter pretty slowly (compared to surrounding areas), but take longer to warm up in the spring.
The ocean often takes the edge of of winter cold snaps, but we can still have long duration cold events that are quite damaging to some borderline hardy plants.
