K4 (WMO 62105) is an offshore North Atlantic buoy west/north‑west of the UK (55.4000°N, 12.2000°W). It was positioned to observe storm waves and swell moving toward northern UK waters, supporting marine warning services. It typically measures directional waves and core meteorology (wind/pressure/air temperature).
