The hour-by-hour forecast where you live in Wales

The Met Office chief forecaster, Paul Gundersen, has explained that the settled weather is down to the jet stream sitting to the north of the UK. He said: "It is holding unsettled weather systems at bay and allowing high pressure to dominate bringing fine weather to the vast majority of the UK.

"The current position of the high pressure means we will see a westerly air flow over the UK - a cooler direction than if air was being brought up from the south and areas such as Spain or Africa. Therefore we are not likely to reach heatwave conditions but temperatures will still be warm reaching the low 20s for many - particularly in the southwest and southern Wales."

While many people will be enjoying the warm weather and topping up their suntans it's important to take care when out in the sun and to beware of the heat. Travel experts have also warned of a busy time on the roads over the bank holiday weekend.

Here is your hour-by-hour forecast and look at the days to come:

Sunday, May 28:

9am

It will be a fine and dry start to the day with plenty of warm sunshine across Wales, according to the Met Office. At 9am temperatures will have reached 16°C in Cardiff but then it will change to cloudy by late morning.

Alternatively the northerly parts of the country will see some sunny intervals, with temperatures set to be around 12°C in Bangor and 14°C in Wrexham, but it will get increasingly warmer in parts as the day goes on.

12pm

By midday it will be cloudier across Wales, particularly in the western and southern parts of the country, compared to what we had on Saturday but it will still feel warm in the sunshine. The highest temperature will be 17°C in parts of Powys while the lowest temperature will be in parts of Gwynedd with 14°C.

3pm

It will turn a little breezier later in the day, particularly around the Welsh coast. In Aberystwyth the wind gust will reach a maximum of 18mph. However temperatures will increase in other parts of Wales. By 3pm Cardiff is predicted to reach 22°C while Swansea is set to see temperatures hit 20°C. It will be 19°C in Newtown and 18°C in Wrexham.

6pm

As the evening draws in temperatures will remain relatively the same. It will be cloudy mostly in the southeast of Wales as well as the northeast of the country. While most of the country will see sunny intervals by 6pm counties such as Anglesey and Pembrokeshire will continue to bask in the sunshine with temperatures set to be around 15°C to 16°C for both areas respectively.

The Met Office forecasts that it will remain largely clear and dry overnight but feeling cool once again under clear skies. It will be breezy with the minimum temperature at 7°C.

Monday:

It is set to be dry once again with sunny spells, according to the Met Office, but perhaps there will be some more cloud around than of late. It will be rather breezy but will still feel pleasantly warm in the sunshine. The maximum temperature is set to be around 19°C.

Outlook for Tuesday to Thursday:

The high pressure will keep it dry and settled with plenty of warm sunshine in Wales. Nights will remain on the cool side with some low cloud possible in the mornings meaning it will be breezy at times.

UK long-range weather forecast:

Thursday, June 1, to Saturday, June 10:

It will be cloudy in the far northeast and near some eastern coasts at times according to the Met Office with low cloud and the odd spot of drizzle drifting inland but turning back to the North Sea coast during the morning. But otherwise it will be generally dry with clear and sunny spells.

Perhaps there will be the odd shower in the far south later on Thursday and there will be light to moderate winds as well. It will be a locally chilly start in places then warm by day. It will be very warm in sheltered west and northwest areas but still rather cool on eastern windward coasts.

Later most places are likely to be dry with sunny periods. There is a chance that thundery showers could affect the far south at times. Winds will probably be light away from coasts and temperatures will likely be above average for most but locally cool near coasts, especially in the east.

Sunday, June 11, to Sunday, June 25:

A north and south split is possible as June progresses with northern areas having a better chance of continued dry conditions, the Met Office predicts, whereas the south may be slightly wetter than average. Winds may also be stronger in the southern half of the country but remain light in northern regions. In general the temperatures are likely to be above average . Eastern coastal areas may feel slightly cooler, however, in the presence of onshore winds.
