K1 (WMO 62029) is a UK Met Office offshore data buoy in the Atlantic approaches southwest of the UK (48.5900°N, 12.4400°W). It was positioned to give early observations of Atlantic swell and marine weather moving toward the English Channel and Celtic Sea, improving forecasts and shipping safety. It typically measures directional waves (significant wave height, peak/mean period and direction) plus core meteorology (wind, air temperature and pressure), transmitting near-real-time observations.
