Galveston Tide Chart: Longest Run of Falling Daily Low Tides

The answer

In NOAA's 30-day Galveston sequence, the longest run of station-local days with a lower daily minimum listed low tide than the preceding day is 8 days, from 2026-11-19 through 2026-11-26.

How it was calculated

This page groups NOAA predictions by station-local date, finds each date’s lowest listed low tide, and compares each daily minimum with the prior day. It does not interpolate between NOAA’s listed turns.

This is a planning aid from predicted tide turns, not observed water levels or a safety guarantee.
