Wind off Hayden Island

–
Forecast wind at 10 m in knots. Line color matches the strip above; the shaded band reaches up to gusts. Arrows point downwind.

Tide at Vancouver

–
Measured Expected (prediction + today's river offset) NOAA prediction Too shallow
NOAA station 9440083, feet above MLLW.

River forecast at Vancouver

–
Measured River forecast Too shallow
Stage at the I-5 bridge gage (NWRFC VAPW1), river flow and tide combined. Depth check: river-forecast method.

River current at the I-5 bridge

–
Knots. Above zero is ebb (flowing downriver), below zero is flood. Measured at one spot in the channel, so midchannel runs faster and the shallows slower.

River below Bonneville

    The allowance is added to your draft to get the water you need (river low + tide). The default 2'4" turns a 5'8" draft into 8 ft at the marina entrance. Lower it for less margin, raise it for more.

    River

    The river-forecast method reads the Vancouver gage directly. Its level needed is your minimum water minus the calibration; 6.3 matched the tide method on average in late September 2026. Adjust it as you learn how the gage lines up with the marina entrance.

    Settings and the time range are saved in this browser. Wind forecast comes from Open-Meteo for the channel north of Hayden Island: high-resolution HRRR for roughly the first two days, then coarser global models, so treat days 3 to 7 as a trend rather than a promise. Current wind is the NWS observation at Portland airport plus the NOAA Vancouver PORTS sensor when it reports. The expected tide line adds the recent gap between measured and predicted levels to NOAA's prediction, which works well when the river is steady and drifts when Bonneville releases change.
