How accurate are tide predictions for Multnomah Channel, OR?
Predictions come from NOAA harmonic analysis of long-term water level records at this station, which is why tide tables can be published years in advance. Astronomical timing is very reliable, but actual water level can run higher or lower with sustained wind, barometric pressure, and river flow — Perigee overlays live observed water levels on the chart above so you can see today's difference.
