…is a four-times-daily BBC radio broadcast of weather reports and forecasts for the seas around the coasts of the British Isles. It is produced by the UK Meteorological Office (part of the Ministry of Defence) and broadcast by BBC Radio 4 on behalf of the Maritime and Coastguard Agency (part of the Department for Transport). The forecasts sent over theNavtex system use a similar format, and the same sea areas.

Because of its unique and distinctive sound, the broadcasts have an appeal beyond those solely interested in nautical weather.
