Peahi Jaws

Maui north and west shore forecast; official shore-facing range: 3–5 ft

Updated Tue, Sep 22, 2:20 PM HST

When to go

7:00 AM–9:00 AM

Strong wind — difficult conditions · Low confidence

3–5 ft · Official surf · whole shore and forecast period · Maui north and west shore forecast; official shore-facing range

Strong wind: 16.1 kt · cross-shore

Cautions

Strong wind or gusts up to 27.4 kt can make the session difficult; being first in the list does not make conditions good.
Strong wind or gusts up to 29.4 kt can make the session difficult; being first in the list does not make conditions good.
Strong wind or gusts up to 33.2 kt can make the session difficult; being first in the list does not make conditions good.

Forecast details

The official forecast calls for surf along this coast.
This is the best time in the forecast, though wind may make it choppy.

Other wind windows

Plan around the wind

The best available upcoming daylight wind sample to compare with the wave evidence. This compares wind only; wave size, tide suitability, and hazards can change your choice.

7:00 AM–9:00 AM · Pacific/Honolulu
Strong wind · up to 16.1 kt · reported gusts up to 33.2 kt
Caution: This is the best available wind comparison, not a favorable-wind label. Strong wind remains in the selected evidence.
Offshore waves: 7.4–7.4 ft across the period. Surf height unavailable. Tide data available; check the local tide response.
Wind source time: Sep 22, 1:30 PM HST. This is not the model run issue time.

How these periods are chosen

The planner prefers three consecutive hourly samples covering two daylight hours, but retains shorter one- or two-sample evidence when that is all the forecast provides. Light wind means at most 6 kt. Moderate offshore means at most 12 kt from land toward the sea when shore orientation is verified. Strong wind or known gusts of 20 kt or more remain visible as cautions instead of making the entire comparison disappear. These are comparison labels, not locally tested surf-quality or safety ratings. Missing gusts remain unknown. Terrain shelter, currents, closures, and your ability are not assessed.

Forecast confidence

Returned marine grid point is 9.7 km from the mapped spot. MFWAM is approximately 8 km resolution.
Reference model hour: 18 hours from now; historical residuals do not measure forecast lead-time error.
No accepted local model for these inputs: missing history, unsupported direction/period/height, or failed historical validation.
A mapped coordinate does not establish nearshore grid resolution or terrain/shelter accuracy.

Source availability is not forecast accuracy. Where an empirical model passes historical testing, its error and interval coverage are shown above. Source count cannot increase that confidence.

How best guesses are made

Best guesses combine usable wave and wind evidence, with qualitative confidence and specific limitations. A missing tide or local surf-height model does not prevent useful guidance. Tide levels use the named station datum; their effect at this break remains uncertain. Wind direction is relative to the mapped beach orientation, without calibrated terrain or shelter effects. The comparison is a heuristic, not a measured quality rating.
