The Shipping Forecast is a BBC Radio broadcast of weather reports and forecasts for the seas around the British Isles. It is produced by the Met Office and broadcast by BBC Radio 4 on behalf of the Maritime and Coastguard Agency. The forecast dates back over 150 years. There are currently two or three broadcasts per day, at 00:48, 05:34, and 17:54 (weekends only) UK local time. It was first broadcast on BBC Radio on 4 July 1925.

In the forecast, the waters around the British Isles are divided into 31 sea areas, also known as weather areas. The forecast begins by listing areas with gale warnings, followed by a general synopsis of pressure areas, then a forecast for each individual sea area covering wind speed and direction, precipitation, and visibility. Extended forecasts at 00:48 and 05:34 include information from coastal weather stations and an inshore waters forecast.

The unique and distinctive presentation style of these broadcasts has led to their attracting an audience much wider than that directly interested in maritime weather conditions. It is frequently referred to and parodied in British popular culture.

History

Robert FitzRoy circa 1850

The Shipping Forecast was established by Vice-Admiral Robert FitzRoy, the first professional weather forecaster, captain of and founder of the Met Office. In October 1859, the steam clipper Royal Charter was wrecked in a strong storm off Anglesey; 450 people lost their lives. In response to this loss, FitzRoy introduced a warning service for shipping in February 1861, using telegraph communications. This remained the United Kingdom's Met Office primary responsibility for some time afterward. In 1911, the Met Office began issuing marine weather forecasts which included gale and storm warnings via radio transmission for areas around the British Isles. This service was discontinued during and following the First World War, between 1914 and June 1921, and again during the Second World War between 1939 and 1945.

The programme, then called Weather Shipping, first took the form of a radio broadcast on 1 January 1924 in Morse Code over the Air Ministry's radio station. From 4 July 1925, it has been transmitted as a spoken word broadcast by the BBC.

Today, although most ships have onboard technology to provide the Forecast's information, they still use it to check their data.

On Friday 30 May 2014, for the first time in more than 90 years, BBC Radio 4 failed to broadcast the Shipping Forecast at 0520. Staff at Broadcasting House were reading out the report but it was not transmitted. Listeners instead heard BBC World Service.

The 150th anniversary of the shipping forecast was on 24 August 2017, while the 100th anniversary of the BBC's version was on 4 July 2025.

Between 30 March 2020 and 5 July 2020, as a result of emergency rescheduling because of the COVID-19 pandemic, the number of bulletins a day was reduced to three, at 00:48, 05:33, and either 12:03 (weekdays) or 17:54 (weekends).

Broadcast times and frequencies

From 1 April 2024, there is no longer a separate long wave schedule for Radio 4, so the number of broadcasts per day has been reduced to two on weekdays and three at weekends, at the following (UK local) times. They can be received on long wave, FM, DAB, Sky, Freeview, Freesat, Virgin Media and online via BBC Sounds.

  • 00:48. Includes weather reports from an extended list of coastal stations at 00:52 and an inshore waters forecast at 00:55 and concludes with a brief UK weather outlook for the coming day. The broadcast finishes at approximately 00:58.
  • 05:34 (from 24 March 2025 - previously at 05:20). Includes weather reports from coastal stations at 05:38, and an inshore waters forecast at 05:40.
  • 17:54 (Saturdays and Sundays only).

The forecasts are read by the duty announcer. Until 23 March 2025, the 05:20 forecast was read by the weather forecaster.

Until 31 March 2024, there were four broadcasts per day at the following (UK local) times:

  • 00:48 – transmitted on FM and LW.
  • 05:20 – transmitted on FM and LW.
  • 12:01 – normally transmitted on LW only.
  • 17:54 – transmitted only on LW on weekdays, as an opt-out from the PM programme, but at weekends transmitted on both FM and LW.

Longwave

The Shipping Forecast has been broadcast on BBC longwave radio services so the signal can be received clearly at sea all around the British Isles, regardless of time of day or radio conditions. The forecast was broadcast on the BBC National Programme until September 1939, and then after the Second World War on the BBC Light Programme (later BBC Radio 2) until November 1978. When BBC Radio 4 took over the longwave frequency from Radio 2 on 23 November 1978, the Shipping Forecast was moved to Radio 4 to keep it broadcasting on longwave.

As part of the BBC's plans to switch off BBC Radio 4 longwave transmissions, it reduced daily broadcasts of the Shipping Forecast to the FM simulcast schedule of twice on weekdays and three times on weekends in April 2024.

Online

The Shipping Forecast is published online by the Met Office and the BBC. It is also available on BBC Sounds.

Television broadcasts

On 18 December 1993, as part of the Arena Radio Night, BBC Radio 4 and BBC 2 collaborated on a one off simulcast so the shipping forecast – read that night by Laurie Macmillan – could be seen as well as heard. To date, it is the only time that it has been broadcast on television.

Broadcast format

The Shipping Forecast follows a very strict format. Excluding the header line, it has a limit of 350 words—except for the 0048 broadcast, where it is increased to 380 to accommodate Trafalgar's inclusion.

Forecast times are spelled out as digits on the 24-hour clock, for example "two-three-double-O", and barometric pressures are pronounced as whole numbers, for example "a thousand and five". With regard to the timing of weather events, the words "Imminent", "Soon" and "Later" are used and are tightly defined. "Imminent" means within 6 hours, "Soon" means within 6 to 12 hours and "Later" means within 12 to 24 hours.

The basic order of the forecast is:

  1. Gale warnings in force (if any)
  2. General synopsis
  3. Area forecasts: wind direction/speed, weather, visibility, ship icing if any
  4. Coastal weather stations (00:48 and 05:20 only): wind direction/speed, precipitation if any, visibility, pressure
  5. Inshore waters (00:48 and 05:20 only): wind direction/speed, weather, visibility

Introduction, gale warnings, and general synopsis

The forecast begins with "And now the Shipping Forecast, issued by the Met Office on behalf of the Maritime and Coastguard Agency at xxxx today." This format is followed quite strictly, although some continuity announcers read out the actual date of issue as opposed to the word "today".

This is followed by gale warnings (winds of force 8 or more on the Beaufort scale), if any (e.g., "There are warnings of gales in Rockall, Malin, Hebrides, Bailey, and Fair Isle"). This sometimes follows the opposite format (e.g., "There are warnings of gales in all areas except Biscay, Trafalgar and FitzRoy").

The general synopsis follows, giving the position, pressure (in millibars) and track of pressure areas (e.g., "Low, Rockall, 987, deepening rapidly, expected Fair Isle 964 by 0700 tomorrow"). With the information provided in the Shipping Forecast it is possible to compile a pressure chart for the coasts of northwestern Europe.

Area forecasts

Each area's 24-hour forecast is then read out. Several areas may be combined into a single forecast where the conditions are expected to be similar. Wind direction is given first, then strength (on the Beaufort scale), followed by precipitation, if any, and (usually) lastly visibility.

Change in wind direction is indicated by "veering" (clockwise change) or "backing" (anti-clockwise change). Winds at or above force 8 are also described by name for emphasis, i.e., Gale 8, Severe Gale 9, Storm 10, Violent Storm 11 and Hurricane force 12. The word "force" is only officially used when announcing force 12 winds.

Visibility is given in the format "Good", meaning that the visibility is greater than 5 nmi; "Moderate", where visibility is between 2 and nautical miles; "Poor", where visibility is between 1,000 metres and two nautical miles and "Fog", where visibility is less than 1000 m. When severe winter cold combines with strong winds and a cold sea, icing can occur, normally only in sea area Southeast Iceland; if expected, icing warnings (light, moderate or severe) are given as the last item of each sea area forecast.

Icing can be a dangerous problem for ships; accurate forecasting can save lives by ensuring crews are prepared

Examples of area forecasts: :* "Humber, Thames. Southeast veering southwest 4 or 5, occasionally 6 later. Thundery showers. Moderate or good, occasionally poor." :* "Tyne, Dogger. Northeast 3 or 4. Occasional rain. Moderate or poor." :* "Rockall, Malin, Hebrides. Southwest gale 8 to storm 10, veering west, severe gale 9 to violent storm 11. Rain, then squally showers. Poor, becoming moderate." :* "Southeast Iceland. Northerly 7 to severe gale 9. Heavy snow showers. Good, becoming poor in showers. Moderate icing."

On 10 January 1993, during the Braer Storm, a record North Atlantic low pressure of 914 mb was recorded. The shipping forecast was: :* "Rockall, Malin, Hebrides, Bailey. Southwest hurricane force 12 or more."

Coastal weather stations and inshore waters

Extended shipping forecasts (00:48 and 05:20) also include weather reports from coastal weather stations followed by a forecast for the inshore waters of the United Kingdom. This additional information does not fall within the 350/380-word restriction.

The reports for coastal weather stations use the following format: name of the station, wind direction/speed, precipitation (if any), visibility in miles, barometric pressure, and trend in pressure. For example, "Machrihanish Automatic. West by south 6, rain, 1 mile, 981, falling more slowly."

The inshore waters forecast begins with a summary of the general situation, followed by forecasts for coastal sections, moving clockwise, using a format similar to that used for sea areas.

"Sailing By"

The 00:48 Shipping Forecast, at the end of the broadcast day, is traditionally preceded by the playing of "Sailing By", a light orchestral piece by Ronald Binge. This is only very rarely omitted, generally when the schedule is running late. Though occasionally played in full, it is common for only a section of the piece to be broadcast; that section being the length required to fill the gap between the previous programme's ending and the start of the forecast at precisely 00:48. "Sailing By" serves as an identification tool – it is distinctive and as such assists anyone attempting to tune in. The forecast is then followed by a more general weather report, the sign-off, traditionally ending with the presenter wishing the audience a good night, the national anthem "God Save the King" and the closedown of the station for the day, with the BBC World Service taking over the frequencies after the pips of the Greenwich Time Signal at 01:00.
