San Francisco Tides: Longest Gap Between Listed High Tides

The answer

For San Francisco, California, the longest gap between consecutive NOAA-listed high tides from October 1 through October 30, 2026 is 15 hours 37 minutes: 2026-10-16 15:11 to 2026-10-17 06:48, in station local time.

What this interval means

This is the elapsed time between two consecutive NOAA prediction entries of the same tide type. It is a scheduling reference, not a measurement of water depth, clearance, current strength, or safety.

The displayed events are predictions in feet relative to Mean Lower Low Water (MLLW). Weather and local conditions can make observed water differ from a prediction.
