Steffan has live and pre-record presenting experience on both TV and Radio. He appears on a weekly basis on S4C, and can often be heard on BBC Cymru and BBC Radio Cymru.


Starting out on his career at 21 years of age, Steffan was, and still is, the youngest person ever to present the weather on S4C. He presents several live and pre-recorded bulletins per day with the former mainly during Spring and Summer events across Wales. Working closely with the UK National Met Office, he combines his scientific knowledge with a natural and relaxed, but professional style meaning he is often referred to as 'warm' on-screen.


Due to his expertise, Steffan often reports on environmental and climate related issues from within Wales and beyond for Wales' main magazine show - HENO. Recent reports include the reduction in air pollution as a result of COVID-19, carbon footprint of agriculture versus vegan products, and the 10 year anniversary of Eyjafjallajökull volcano eruption in Iceland.


As the resident S4C weatherman, Steffan is often heard on BBC Radio Cymru talking about all things Weather and Climate, or promoting one of his other documentaries.
