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.

3:00 PM–5:00 PM · Pacific/Auckland
Strong wind · up to 11.8 kt · reported gusts up to 27.0 kt
Caution: This is the best available wind comparison, not a favorable-wind label. Strong wind remains in the selected evidence.
Offshore waves: 1.3–1.4 ft across the period. Surf height unavailable. Tide data unavailable.
Wind source time: Sep 23, 11:45 AM GMT+12. 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 10.1 km from the mapped spot. Provider grid resolution is not established for this response.
Reference model hour: 0 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.
Tide unavailable: assessment incomplete, especially at shallow reef breaks.
A mapped coordinate does not establish nearshore grid resolution or terrain/shelter accuracy.

About this spot

Model-grid forecast requested at the mapped coordinate; reef, headland, and nearshore transformations are unresolved. Beach break. Published named-break coordinate; the source describes a beach break receiving NNE swell with SSW offshore wind.

Mapped spot coordinate: -37.63, 176.18.

North Island · Bay of Plenty north-northeast-facing exposed beach coast · Ocean-facing bearing 22.5° · Location provenance

Model request point: Mount Maunganui (-37.63, 176.18). Model output times describe valid conditions; the provider does not expose the model run issue time in this response.

Data coverage 2/6 sources

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.
