Galveston Tide Turns: What the Next 30 Days Show
From September 26, 2026 through October 25, 2026, the largest NOAA-predicted turn-to-turn range at Galveston Channel, Texas is 1.907 ft (0.581 m converted) on October 1, 2026; the smallest is 0.000 ft (0.000 m converted) on October 15, 2026.
The answer
The 30 local dates contain 2 days with three listed turns and 15 days with four listed turns. This count reports the prediction sequence returned for this station; it does not add an event where NOAA returned none.

How this was calculated
For every local calendar date, this page takes the highest and lowest value in that date’s NOAA high/low prediction sequence, then subtracts the low from the high. Feet are the official response values; metres are calculated from feet and labeled as conversions.
Heights use Mean Lower Low Water (MLLW). A predicted range describes listed tide turning points, not observed water depth, launch clearance, or safety conditions.
