Daily Tidelog Graphics are based on NOAA predictions for Boston, MA with times and heights for Boston and Portland, ME. Time and strength of maximum currents and times of slack water are shown daily at Boston Harbor, at Deer Island Light and Portsmouth Harbor Entrance, ME. Included at the back of the Tidelog are tide tables for Nantucket, MA, Bar Harbor and Eastport, ME and current tables for Estes Head, in Eastport ME and Bucksport, in Penobscot Bay, ME.
