Regional Forecast for Wales

Headline:

Dry and sunny. Becoming hot into the new working week.

This Evening and Tonight:

Evening sunshine will give way to a dry and clear night with light winds, and once again it will become fairly cool, especially in rural areas. Minimum temperature 7 °C.

Monday:

Something of a repeat of Sunday, with another dry and sunny day expected. Feeling hot inland, but cooler along the coast where sea breezes develop. Maximum temperature 27 °C.

Outlook for Tuesday to Thursday:

Dry, sunny and hot, though sea breezes will keep coastal areas somewhat cooler. Night time temperatures will start to increase too, especially in built-up areas.

Updated: 15:51 on Sun 24 Jun 2018 BST

UK forecast for the next 5 days

Headline:

Largely dry and sunny and becoming hot into next week.

This Evening and Tonight:

Another largely dry, clear night and becoming quite cool once again away from larger towns and cities in the south. Perhaps cloudier with occasional drizzle across northern and northwestern Scotland.

Monday:

Unbroken sunshine for many parts of the UK with temperatures higher than the weekend. Cloudier and cooler across northern Scotland, and also cooler where sea breezes develop.

Outlook for Tuesday to Thursday:

Dry, mostly sunny and becoming hot across central, western and some northern areas. Somewhat less hot across the southeast at least at first, and also where sea breezes develop.

Updated: 15:45 on Sun 24 Jun 2018 BST

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 29 Jun 2018 to Sunday 8 Jul 2018:

The final few days of June will stay dry and sunny across much of the UK, although it may be cloudier with a chance of rain at times in the far north of Scotland. It will feel cooler than of late across parts of Scotland but elsewhere it will remain very warm or hot. The heat may spark a few showers or an isolated thunderstorm during the first week of July, but the majority of the UK will stay fine and dry. However, most areas should continue to see plenty of fine, sunny and very warm weather. Northwestern areas may however begin to see cloudier conditions pushing in, with the chance of some wet and windier weather here at times.

UK Outlook for Monday 9 Jul 2018 to Monday 23 Jul 2018:

The most likely scenario is that we will see a good deal of dry and settled weather across many parts of the UK with very warm temperatures likely at times. There are some early indications that in the north and west, more changeable conditions could bring cloudier skies, and possibly some wet and windy weather at times. There may also be some interludes of more unsettled, cooler conditions bringing some outbreaks of rain or showers across the rest of the UK at times, but these will be short lived with dry, fine weather likely for most of the time.
