Brecon Beacons National Park Weather Forecast

The Brecon Beacons National Park is one of three National Parks in Wales, covering 519 square miles and encompassing four main regions; the Black Mountains in the west, Forest Fawr and the Brecon Beacons in the centre, and the Black Mountains in the east.

Area: 1344 sq km

Designated: 1957

Despite being accessible from the industrial South Wales valleys within just half an hour, the Brecon Beacons offers visitors feelings of real expanse and isolation. This was verified officially in 2013, when the National Park was also granted status as an International Dark Sky Reserve by the International Dark Sky Association. This remoteness, with the beacons only dotted with small towns and villages, means there is very little artificial light to mute the night-time tapestry of stars.

Most of the park is bare, grassy moorland, grazed by Welsh mountain ponies and Welsh mountain sheep. It is also known for its remote reservoirs, waterfalls and caves.

Visitors and locals can participate in activities including walking, cycling, mountain biking, horse riding, sailing, windsurfing, fishing and many more.

The Brecon Beacons National Park weather page provides a 5 day weather forecast for many places within the Park and the surrounding area, featuring 3 hourly updates on weather conditions for rainfall, temperature, wind speed and wind direction.

In 1949, following protests and campaigns, a measure was introduced by the UK government to protect and conserve some of the most beautiful areas of England and Wales. Within two years, the first sites were given the newly-named 'National Park' status: the Peak District, Lake District, Snowdonia and Dartmoor. Over the years that have followed, 11 more areas have been given similar status, thereby taking the total to 15.

Now, the National Parks are a source of immense pride for Brits and bring in millions of pounds through tourism every year. Whilst all are rural areas perfect for quiet days out, each park differs greatly and has its own attractions that are responsible for bringing in enthusiastic visitors.

Some of the most spectacular and valued countryside in the UK can be found in these areas. As well as welcoming visitors, National Parks are places where at least 331,000 people live, work and shape the landscape.

Nearly 4,000 ancient monuments are located in the National Parks across England, Scotland and Wales. The oldest National Park, the Peak District, was founded in 1951 while the newest, the South Downs, was only established in 2009. The largest National Park, the Cairngorms in Scotland, covers 1,467 square miles.

At the Met Office we forecast for all of the National Parks. Each of the areas contains a variety of landscapes, many with mountains and high peaks which can experience extreme and changeable weather.
