gustcheck shows what the wind is doing right now, not what it's forecast to do. Readings come straight from NOAA's 6-minute harbor stations (CO-OPS), NDBC buoys and airport METARs — the same sensors other apps show an hour late. Direction is where wind is from. Age colors: ■<10 min ■10–60 min ■>60 min; stale readings are dimmed, never hidden. Tap a station for its 24-hour history and a link to the raw source. Want a forecast? Each station links to Windy.
