Channel Lightship (WMO 62103) is a long‑running offshore observation station in the English Channel (49.9170°N, 2.8830°W). It is positioned to monitor conditions on a major shipping route and to capture swell and wind sea entering the Channel. It reports directional wave statistics (height/period/direction) and standard meteorology (wind, pressure, air/sea temperature) for forecasts.
