Off-the-shelf wave and wind products, official NWS coastal guidance, and the nearest live buoy are kept separate. Barcrosser does not blend them; provider-built blends are clearly labeled. Recent Westport accuracy ordering focuses attention while every forecast stays visible.

How the color works

Height and spacing together

Red follows the WFO Seattle Small Craft Advisory seas criterion used around Westport: seas at least 10 ft, or 7–9 ft when the period in seconds is shorter than the height in feet.

Below that line, Barcrosser uses transparent display bands: rough at ≥7 ft or H/T ≥.8; elevated at ≥4 ft or H/T ≥.5; otherwise lower energy. H/T is an empirical spacing signal, not a physical unit or safety verdict.

MFWAM global wave model: 3.7 ft / 7 s = 0.53 H/T

Westport nearshore is evaluated as open-water guidance. Bar-specific risk also depends on current phase, water depth, bathymetry, wind opposition, and the exact entrance channel. Outside WFO Seattle waters, use the responsible office’s local criteria; this remains a Westport-tuned comparison scale.
