they are off and on, many many days are breezy enough so that you need nothing, but always bring some along for if the breeze stops or if you head into the more away from the wind areas, say away from town up north or south...

generally along the eastern shore the wind takes care of the bugs. but have some high-deet stuff with you, just in case.

bring sunscreen, aloe vera, bug spray, lip protection (with sunscreen).
