The year as a print
The last two days, measured
Station 8725110 has no water-level gauge: NOAA publishes its prediction here, not a measurement. The computed curve stands alone, and the week's table above is its check.
- Computed here, from the constants
- NOAA's own prediction
- Measured at the gauge, every six minutes
Measured heights from NOAA CO-OPS station 8725110, preliminary, above mean lower low water. The print carries the computed curve only: one year, no weather.
