Portland, Maine Tide Chart: Longest Run Beginning With a High Tide

The answer

In NOAA's retained 30-day Portland, Maine sequence, the longest consecutive run of station-local dates beginning with a listed high tide is 9 days, from 2026-11-11 through 2026-11-19.

How this result was calculated

This page groups listed NOAA predictions by station-local date, labels each day by its first listed turn, and finds the longest consecutive run whose first turn is high. It does not infer turns that NOAA did not list.
