St. Catherine Cove is a subordinate station: NOAA computes its tides from Unalaska with fixed time and height corrections.

Moving water at dawn and dusk —

The current runs fastest roughly halfway between a high and a low tide. Many anglers prefer those hours when they fall near sunrise or sunset. This is a rule of thumb, not a fishing forecast.

When are the highest tides of the year at St. Catherine Cove?

The highest predicted tide in the next 12 months is 6.3 ft on December 23, 2026 at 2:55 PM. The largest tides fall a day or two after a full or new moon, especially when the Moon is closest to Earth.

Are there minus tides at St. Catherine Cove?

Yes — on 215 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -2.1 ft on June 6, 2027 at 1:51 PM. Minus tides expose the most shoreline, which is why tide-poolers look for them.

What time zone are these tide times in?

Station local time (AKDT at the time this page was built), with daylight saving time applied where the area observes it — the same convention as NOAA's own tide tables.

Where does this tide data come from?

From NOAA CO-OPS, the U.S. government tide station network (tidesandcurrents.noaa.gov); the predictions are public domain. St. Catherine Cove is a subordinate station: NOAA derives its times and heights from the reference station Unalaska with fixed corrections. The curve between highs and lows is our interpolation.
