    Regional forecast for Wales

    Increasingly humid, with some thunderstorms possible next week.

    Any showers soon dying away, otherwise evening sunshine will give way to a dry night with clear spells and a few mist patches. Staying rather warm in towns and cities. Minimum Temperature 13 °C.


    Most parts will dry with variable cloud, sunny spells and an increasingly humid feel. Some coasts and hills in the west and north may become rather misty at times. Maximum Temperature 27 °C.

    Outlook for Monday to Wednesday:

    Often very warm and humid, with some sunshine, but also the risk of some heavy thunderstorms developing. Northern and western areas could be rather cloudy at times, with showery rain.

    UK forecast for the next 5 days

    Increasingly humid this weekend. More hot weather next week.


    A cloudy start for many, but it will brighten up with some sunshine by the afternoon. That said, a few showers are likely to break out, with the odd heavy one in the south. Hot again in the southeast.


    Showers dying out to leave clear spells and a few mist patches across England and Wales. Damp across northern and western Scotland and Northern Ireland, with some hill fog.


    Occasional rain in the northwest, with fog affecting some other western coasts and hills. Otherwise variable cloud and some sunshine, but an increasingly humid feel. Much warmer across eastern Scotland.

    Outlook for Monday to Wednesday:

    Rain in the northwest will erratically move southeast. Northwest of this, turning brighter and fresher with a few showers. To the southeast, largely sunny and hot, but isolated thunderstorms developing.

    Outlook for the UK over the next 6-30 days

    UK Outlook for Wednesday 25 Jul 2018 to Friday 3 Aug 2018:

    A good deal of fine, settled weather for most, particularly at first, with sunny spells and light winds, but with the risk of some thundery showers, especially in the southeast. Increasing threat of some organised rain spreading into western areas. Staying very warm, locally hot in the south. Looking further ahead a west-east split in conditions is likely to develop, with eastern and southeastern areas probably drier, more settled, very warm and increasingly humid, but always with the risk of isolated showers and thunderstorms. Further west it may be more changeable and breezy with some outbreaks of rain or showers, but also some drier and brighter interludes. Temperatures nearer normal in the west, but generally very warm elsewhere, with hot or very hot conditions at times, especially in the southeast.

    UK Outlook for Saturday 4 Aug 2018 to Saturday 18 Aug 2018:

    Throughout this period it seems most likely that the weather pattern will only evolve very slowly. The west of the UK is likely to see more in the way of breezier, cloudier conditions with some rain or showers at times, with these occasionally affecting other areas. Elsewhere, especially in the east, drier and more settled weather is expected to dominate, although with the ongoing risk of a few heavy showers or thunderstorms breaking out at times. Temperatures remaining above average for most, with the potential for further spells of very warm or hot conditions, and possibly very hot, especially in the southeast. Temperatures are likely to be often nearer normal in the west and northwest.
