The first BBC Weather Forecast aired on radio on 14 November 1922, and the daily forecast first aired on 26 March 1923. The first bulletin was then aired in 1936.
Before this logo was launced, they just used a regular BBC logo. This BBC Weather logo was introduced in October 1997, but wasn't seen on-screen in the forecasts themselves until 2000.
The service introduced 3D weather maps and globes in May 2005.
As the BBC is slowly changing from Gill Sans to BBC Reith, BBC Weather adopted the font on its logo and graphics in June 2019 replacing Helvetica.
