We publish a detailed Inshore Waters (up to 12 miles offshore) forecast for 17 areas around the coast of the UK twice a day at 0500 and 1700. Each area receives a 24 hour forecast, followed by an outlook for the following 24 hours. A general three day outlook is also available. The date and time of issue are found in the header of the full text forecast. The 17 area Inshore Waters forecast is broadcast on Radio 4 at approximately 0526 (local time).
A 24 hour forecast with 9 areas only is broadcast after the main shipping forecast at approximately 0053 (local time). This is updated with the issue of strong wind warnings. These are not broadcast on Radio 4 but via local radio and Coastguard stations.
