A generic read is not your go/no-go
"Charleston Harbor is GO" is a generic small-craft picture. Whether you should go out depends on your boat, your experience, and your own limits: the wind, seas, and visibility numbers you set as your own limits. GoNoGo WX scores Charleston Harbor's live conditions against your own boat and gives you one straight answer: GO, CAUTION, or NO-GO.

What drives a marine go/no-go
Wind (sustained and gusts) is the single biggest driver of a rough, wet ride and of a small-craft advisory. Seas (wave height plus period: a short, steep 4 ft chop beats you up worse than a long 4 ft swell). Visibility and fog (losing the shoreline and other traffic is a real hazard under way). Lightning (thunderstorms on an open boat are a stay-in read). These are read live from official NOAA/NWS marine data, nearby buoys, and modeled swell, and refresh through the day.
