10 Day Forecast for brecon

Wet and windy tonight. Sunshine and showers tomorrow.

This Evening and Tonight:

A band of heavy rain and strong, squally winds will move eastwards across Wales this evening, bringing gales mainly to hills and exposed coasts. Further rain or showers overnight with strong winds and some coastal gales, mainly for western parts. Minimum Temperature 8C.

Friday:

Windy with a mixture of sunshine and heavy, blustery showers. Frequent showers in the morning becoming fewer and further between for the afternoon and evening. Winds easing later. Feeling cool. Maximum Temperature 16C.

Outlook for Saturday to Monday:

Saturday, rain in the south, possibly, drier in the north. Rain overnight into Sunday, then becoming drier. Drier, brighter and more settled on Monday.

Day 6 to 15

For most of the UK it looks like the weather should remain largely settled through the rest of September. Most places will have long sunny periods and generally light winds. However, some mist and fog patches will form during the nights. The far north and northwest will most likely turn a little more changeable through next week with some rain and strong winds. Weakening bands of rain are expected to push southeastwards across the UK but they will become increasingly patchy as they go. Days will be warm for many, at least at first, but nights will be chilly with some localised frost. Into the start of October many parts are set to remain mostly settled, though some wet and windy weather is possible further north.

Day 16 to 30

Settled conditions are expected to dominate across much of the UK through the beginning of this period, especially in the south. There should be a good deal of dry and bright weather with any brief wet and windy spells likely to be confined to the north of the UK. Increasingly long nights nights will lead to a greater risk of patches of fog forming overnight and some places may also see some frost. Despite chilly nights, any sunshine by day will give a rather warm feel. Later on in this period there is considerable uncertainty in the forecast with a chance that some more unsettled weather may become established again.
