He was educated at Todmorden Grammar School, he played cricket for Burnley and Todmorden. A geography teacher at his school sparked his interest in weather forecasting. He started Geography A-level, but never took the exam.

He worked at the meteorological office at Manchester Airport for two years from 1970 before studying applied health and social care at what is now Coventry University, where he met his wife. He spent four years researching meteorology. He trained for a year in weather presentation at the Met Office College, Shinfield near Reading.

From 1980, he worked at the Nottingham Weather Centre, presenting his first forecast for Radio Lincolnshire, then further forecasts for the BBC's Midlands Today (in the Nottingham news opt-out, starting 28 May 1980) and Central Television. In 1985, he became a national forecaster on the BBC. On Thursday 18 April 1991 he launched the first international weather forecast on the new BBC World Service Television.^[1]

Kettley enjoys playing cricket, fell-walking and horse racing. A supporter of Burnley F.C., he often makes references to the team's performances during broadcasts. He married Lynn in September 1990 in North Lincolnshire. His parents lived in Littleborough.

In 1988 he played cricket (as a bowler) for Ardeley in East Hertfordshire, where he lived.^[6]

He married graphic designer Lynn Grundy at St Andrew's church in Kirton in Lindsey on 12 September 1990, with the service given by Rev Ian Walker. Kettley had known Grundy at his polytechnic, although she went later to the University of Leicester, and designed Ladybird Books in the mid-1980s;^[7][8] his wife had attended Brigg High School for Girls. They have two sons.

Kettley's status was confirmed in 1988, when a band called A Tribe of Toffs released the song "John Kettley Is a Weatherman", which also made reference to other TV weather presenters of the day, including Michael Fish, Bernard Davey, Bill Giles, Ian McCaskill and Wincey Willis. The single reached number 21 in the UK Singles Chart.^[9] The song included the chorus:

John Kettley is a weatherman

A weatherman, a weatherman

John Kettley is a weatherman

And so is Michael Fish

And so is Billy Giles

And so is Ian McCaskill

And so is Wincey Willis
