Jeremy Parr, from Natural Resources Wales, told ITV News the quality of Wales's beaches was important for tourism.
Welsh beaches have been ranked among the best in the UK and across the world with 34 achieving Blue Flag status and 31 obtaining Green Coast Awards.
Pembrokeshire is home to some of the best beaches, winning 10 Blue Flags, followed by Gwynedd with eight and Anglesey with six.
The beaches were judged on criteria including cleanliness, water quality and safety.
Natural Resources Minister Alun Davies says:
"The awards demonstrate the high standard of Welsh bathing water quality and reflect the diversity of our beautiful coastline, which is enjoyed by our communities and the millions of visitors to Welsh beaches each year.
"These awards also recognise the hard work of everyone involved in achieving and maintaining these high standards."
Fresh from receiving his accolade for Best Actor at the BAFTA Cymru awards last night, Michael Sheen visited his home county of Neath Port Talbot today.
He was giving out the awards rather than collecting them this time though - to schools - which are doing their bit for the environment. Joanna Simpson reports.
Hollywood actor, Michael Sheen, will be visiting a school in his home county of Neath-Port Talbot today as part of his role as a Keep Wales Tidy ambassador.
The Welsh star, who won the award for Best Actor at the Bafta Cymru awards last night, will be going to an Eco-Schools award ceremony at Cwm Nedd Primary School in Glynneath where he'll be joined by the Minister for Natural Resources and Food, Alun Davies.
Eco-Schools is an international programme that teaches children to be environmentally responsible from an early age.
Alun Davies, the Minister for Natural Resources, has announced £943,833 to help keep communities across Wales tidy.
The funding will support 75 projects as part of the Tidy Towns initiative which he says will help communities improve their local area and tackle problems like fly tipping, vandalism, dog fouling, and littering.
It's hoped the backing will help transform wasteland across Wales into communal areas like nature reserves, community gardens, allotments and recreational areas.
