Detailed mountain weather forecast: Brecon Beacons
Wednesday
Weather
A cold, dry and largely bright day with a good deal of sunshine around. However, some eastern parts may be rather cloudy with a risk of some locally persistent hill fog. Winds will increase rapidly with height, leading to a risk of chill over the higher peaks.
Visibility
Generally very good, although it will be very poor in any hill fog.
Hill fog
Occasional hill fog likely at around 500 m in some eastern areas. This hill fog will be fairly thin and will readily break up towards the west.
Maximum winds above 400m
Easterly 35 mph.
Temperature
| Valleys | Minus 7 Celsius rising to zero or perhaps plus 1 Celsius. |
| 800 m | Minus 4 Celsius. |
| Freezing level | Temperatures below freezing at all heights to start, with temperatures perhaps rising above freezing in the lowest 50-100 m by mid-afternoon. |
Thursday
Weather
A rather cloudy start but it should remain dry. Through the afternoon some sunny spells should develop, although these may be rather fleeting. Winds markedly lighter than Wednesday, and with temperatures at height significantly warmer there is a vastly reduced risk of chill.
Visibility
Generally very good but very poor in hill fog.
Hill fog
Occasional, possibly widespread hill fog at around 400m initially, this likely to lift and break towards the afternoon.
Maximum winds above 400m
Easterly 10 mph.
Temperature
| Valleys | Minus 4 Celsius becoming zero Celsius. |
| 800 m | Plus 2 Celsius. |
| Freezing level | Temperatures between the surface and 650 m below freezing. Temperatures between 650 m and the highest peaks above freezing, with the general freezing level above the summits. |
Outlook
Friday
A milder but cloudy day with frequent outbreaks of rain, some of which may be heavy, and strong southerly winds. There could also be some spells of snow, particularly over the higher peaks through the morning. Widespread hill fog likely above 100 m. Freezing level well above the summits.
Saturday
A very similar day to Friday, with rather cloudy skies and frequent outbreaks of rain. Once again hill fog is likely above 100 m but the southerly winds should at least be lighter. Freezing level above the summits.
Sunday
Another rather cloudy and dull day with widespread hill fog likely once again. Still the risk of some rain, although it is likely to be lighter and patchier compared to the preceding days. Winds remaining light. Freezing level just above the summits.
