The first BBC Weather Forecast was broadcast on radio on 14th November, 1922, and the daily forecast was first broadcast on 26th March, 1923. The first bulletin was then broadcast 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.
