Detailed mountain weather forecast: Brecon Beacons



Any shallow mist and fog patches in the valleys will soon clear after dawn to leave another fine and dry day across the park with some long spells of sunshine. It will be warm too with just a gentle breeze, and high UV levels will bring a high risk of sunburn.


Very good, but poor in any valley mist or very poor in fog patches.

Hill fog


Maximum winds above 400m

Northeasterly 20mph later.


Valleys Plus 11, becoming plus 24 Celsius.
800 m Plus 15 Celsius.
Freezing level Above the summits.



After a mostly clear night, low cloud will spread in from the east before dawn to give areas of hill fog. This should largely lift and clear by mid-morning though, to leave another warm, dry and mostly sunny day. The odd isolated shower may develop in the afternoon, however high UV levels will again bring a high risk of sunburn.


Very good, but very poor in hill fog.

Hill fog

Areas of stratus down to 300m during the first part of the morning, with isolated patches down to 200m over the eastern slopes.

Maximum winds above 400m

Easterly 30mph.


Valleys Plus 12, rising to 25 Celsius.
800 m Plus 15 Celsius.
Freezing level Above the summits.



Many parts of the park will continue to remain generally fine with warm sunny spells, but there is an increased risk of heavy and perhaps thundery showers developing at times during the afternoon and evening. UV levels will remain high however it should feel a touch cooler than earlier in the week with a moderate easterly breeze.


Although mostly dry and bright or sunny to start, there is a risk of scattered showers developing by afternoon once again. Some of these may turn heavy and become slow-moving with just a light easterly breeze. It will feel very warm on the slopes, with high UV levels bringing a high risk of sunburn.


It will be a cloudier start to the weekend, although still rather bright at times and feeling warm. There's a chance of some showery rain arriving from the west later in the day, perhaps bringing some hill fog. Winds will be mostly light.
