What the grades mean

Grade	Sustained wind	Gusts	Waves	What it means
✓ CALM	< 5.5 m/s	< 8 m/s	< 1 m	Flat water, light air — ideal
✓ GOOD	5.5–8 m/s	8–10.8 m/s	1–1.5 m	Good conditions for the run
≈ MODERATE	8–10.8 m/s	10.8–13.9 m/s	1.5–2 m	Some chop — comfortable with care
▲ ROUGH	10.8–13.9 m/s	13.9–17.2 m/s	2–3 m	Rough — for experienced hands only
✕ NO-GO	≥ 13.9 m/s	≥ 17.2 m/s	≥ 3 m	Too much wind — stay in port

Each hour is graded on the worst of wind, gusts and waves at any of the sampled points. Wind leads: wave limits are deliberately lenient, so a bit of chop won't outvote a calm breeze.

Sampled points — Cabin, Risør Port, Stangholmen (exposed mouth). The tick (│) on each wind bar marks the peak gust.

Judgement, not gospel. Bands are conservative defaults for a 7–8 m leisure boat with family aboard — edit them at the top of boatweather.py. Forecast thunderstorms are flagged (⚡) but this is not live lightning-strike detection; the grade still knows nothing about fog, current or darkness — always cross-check yr.no, look at the actual sea state, tell someone your plan, and wear the lifejacket.
