About Hercules, Refugio Landing tides
Tide predictions for Hercules, Refugio Landing come from NOAA station 9415074 (California), computed from long-term harmonic analysis of observed water levels. Heights are shown in feet relative to MLLW (Mean Lower Low Water) — the same datum used on US nautical charts — so they line up directly with charted depths.
Hercules, Refugio Landing typically sees a mixed semidiurnal tide, with two highs and two lows of differing heights each day. Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide, or clearing a shallow bar — and remember that wind and pressure can push the real water level above or below prediction. The daily tidal range in the 30-day table shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
The current water temperature near Hercules, Refugio Landing is about 61°F, from the nearest reporting buoy (SAN FRANCISCO buoy 46026, 35 mi away). Water temperature shapes where fish hold and feed, and tells you what to wear in the water — check it alongside the tide before you head out.
Frequently asked
What time is high tide in Hercules, Refugio Landing today?+
Today (Saturday, September 12), high tide at Hercules, Refugio Landing is at 1:52 AM (6.0 ft), 2:24 PM (6.2 ft). Heights are referenced to MLLW (Mean Lower Low Water).
What time is low tide in Hercules, Refugio Landing today?+
Today, low tide at Hercules, Refugio Landing is at 8:09 AM (0.5 ft), 8:42 PM (0.6 ft).
What tidal datum do these Hercules, Refugio Landing tide heights use?+
All heights are given in feet relative to MLLW (Mean Lower Low Water), the standard NOAA chart datum for US tidal waters. A tide of 0.0 ft equals the chart datum; negative tides fall below it.
How accurate are these tide predictions?+
These are NOAA harmonic predictions — highly accurate for the astronomical tide. Real water levels can still differ with wind, barometric pressure, and storms, so always check current conditions before getting underway.
What is the water temperature at Hercules, Refugio Landing?+
The latest sea-surface temperature near Hercules, Refugio Landing is about 61°F, from the nearest reporting buoy (SAN FRANCISCO buoy 46026, 35 mi away). Water temperature drives fish behavior and tells you what to wear in the water, so it's worth checking alongside the tide.
