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. Port Houghton, Robert Islands is a subordinate station: NOAA derives its times and heights from the reference station Juneau with fixed corrections. The curve between highs and lows is our interpolation. This page is not for navigation.
