Onion Bay is a subordinate station: NOAA computes its tides from Seldovia, Kachemak Bay 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 Onion Bay?

The highest predicted tide in the next 12 months is 17.9 ft on January 23, 2027 at 2:53 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 Onion Bay?

Yes — on 177 days in the next 12 months the low tide drops below 0 ft (MLLW). The lowest is -4.3 ft on July 5, 2027 at 10:10 AM. 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. Onion Bay is a subordinate station: NOAA derives its times and heights from the reference station Seldovia, Kachemak Bay with fixed corrections. The curve between highs and lows is our interpolation.
