Just back from the morning walk, 32 degrees here this morning. I did my usual check on the temperatures down south. Between 40 and 45 degrees along the coast.
That should be comfortable with the gear I've got. (And look at that nice north wind!) I've done 40 degree nights a few times and once, during an early winter storm, woke to find ice on my boom tent in Chestertown. The more research I do on weather and currents, the better I feel about the trip.
