COASTAL WATERS FROM STONINGTON ME TO MERRIMACK RIVER MA OUT TO 60 NM

ANZ100-272030
230 AM EDT Tue Oct 27 2026

Synopsis for Stonington ME to Merrimack River Ma out to 60 NM

Northwest winds remain gusty through the morning as a cold front exits the coast. High pressure builds in quickly in its wake today. Later this week, as return southwest flow develops, winds may again approach 25 knot gusts along with building seas beyond Monhegan and Matinicus Islands, but otherwise the weather on the waters looks awfully quiet for this time of year.
