Boston Tide Chart: Widest Daily Predicted Tide Range

The answer

NOAA's widest within-date predicted tide range for Boston, Massachusetts in this 30-day sequence is 12.671 ft (3.862 m, converted) on 2026-10-28, from -1.076 ft at 19:38 to 11.595 ft at 13:08.

How this result was calculated

This analysis groups official NOAA prediction entries by station-local date and applies one stated comparison across the 30-day sequence. It uses predictions, not observed water levels, and does not interpolate a tide height or time.
