Telltale has not classified how exposed N3UJJ-1 weather is, so compare it with nearby stations before relying on its absolute numbers.

Reading these numbers

The mean wind is averaged over the station's reporting period, and a gust is the strongest short burst inside it, so a gust is always at least the mean. Speeds are in knots, directions are where the wind blows from, and times are given in UTC with the station's local time beside them. A station measures its own spot; a forecast model describes a grid cell, so the two can differ by a few knots even when the forecast is good. N3UJJ-1 weather is one of the stations Telltale compares with the forecast models before it shapes the live wind map; understand the weather models or how coastal wind behaves.
