Detailed mountain weather forecast: Brecon Beacons



After a largely clear, dry night, low cloud will spread from the east around dawn giving some patches of hill fog. This low cloud should rapidly lift and clear during the morning to leave plenty of sunshine and becoming very warm or locally hot, with a high risk of sunburn. During the afternoon, cloud will develop and could bring isolated thundery downpours for a time towards evening. Any showers will fade during the evening to leave a dry start to the night.


Generally very good, but poor or very poor in early hill fog and mist. Becoming moderate or poor in heavy showers.

Hill fog

Occasional around 300m around dawn, especially over eastern slopes, but this soon clearing to leave summits cloud free.

Maximum winds above 400m

Easterly 20-30mph.


Valleys Plus 14 Celsius rising to plus 27 Celsius.
800 m Plus 15 Celsius rising to plus 17 Celsius.
Freezing level Well above the summits.



Dry overnight with long clear spells but also some patchy low cloud, this more likely towards dawn and in the east. Another bright and very warm day will follow with long sunny spells once any patchy low cloud clears. Many places will remain dry, but showers are likely to develop with some heavy and perhaps thundery downpours possible.


Generally very good, but poor or very poor in any hill fog. Moderate or poor in any heavy showers.

Hill fog

Occasional patches around 400m, these soon burning off to leave summits clear of cloud.

Maximum winds above 400m

Southeasterly 20-30mph.


Valleys Plus 14 Celsius rising to plus 26 Celsius.
800 m Plus 17 Celsius.
Freezing level Well above the summits.



A few mist and hill fog patches initially, then a bright morning with sunny spells. 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.


Any early mist and fog patches soon lifting to allow good sunny spells and a few showers. The showers should be lighter than recently. Winds will be light northeasterly making it feel a little cooler than past days, but still warm.


There is likely to be more cloud than of late, but still with a good deal of dry weather and sunny spells. During the afternoon there will be an increasing risk of showers, perhaps the odd heavy one. Light to moderate northeasterly winds.
