About Avalon, Santa Catalina Island tides
Tide predictions for Avalon, Santa Catalina Island come from NOAA station 9410079 (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.
Avalon, Santa Catalina Island 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 Avalon, Santa Catalina Island is about 70°F, from the nearest reporting buoy (San Pedro South, CA (213) buoy 46253, 18 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.

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 Avalon, Santa Catalina Island?+
The latest sea-surface temperature near Avalon, Santa Catalina Island is about 70°F, from the nearest reporting buoy (San Pedro South, CA (213) buoy 46253, 18 mi away). Water temperature drives fish behavior and tells you what to wear in the water, so it's worth checking alongside the tide.
