Plenty of sunshine for the longest day of the year - just a little cloud around but staying bright.
The cloud across Scotland and Northern Ireland will break up to leave a better afternoon.
In the sunshine it'll be 19-20C in the north, 25C in the south, so a little warmer than of late - but cooler by the coasts.
An estimated 37,000 people saw the sun rise at Stonehenge on the longest day in the calendar.
The Summer Solstice has a long tradition of attracting people to monuments such as Stonehenge, where people gather to witness the dawn.
25 people have been arrested at Stonehenge overnight, police said. Officers with Wiltshire Police said the arrests were largely for drugs-related offences.
Tens of thousands of people gathered in Stonehenge this morning to mark the Summer Solstice at the dawn of the longest day of the year.
The ancient site has been a place of worship and celebration at the time of Summer Solstice since the prehistoric time.
Police arrested 25 people at Stonehenge overnight after an estimated 37,000 people saw the sun rise on the longest day in the calendar.
Officers with Wiltshire Police said the arrests were largely for drugs-related offences.
The Summer Solstice has a long tradition of attracting people to monuments such as Stonehenge, off the A303, where latter-day Druids gather to witness the sun rising on the longest day.
A police spokesman said: "We are pleased that the Solstice celebrations at Stonehenge and Avebury have been enjoyable events for the majority of people attending.
"There were 25 arrests at Stonehenge and two at Avebury which were mainly for drug-related offences."
Crowds have gathered at the ancient stone circles of Stonehenge and Avebury in Wiltshire to celebrate sunrise on the longest day of the year and the beginning of summer.
The prehistoric monument Stonehenge may have been built as a giant xylophone, researchers have claimed. The Royal College of Art spent months tapping more than 1,000 types of rock to study the monument's musical qualities.
Most rocks produced a "dull thud" while the bluestones, which formed the earliest stone circle, were found to "sing" when struck. The rocks made a range of metallic sounds like bells, gongs and tin drums, the study confirmed.
Paul Devereux, who led the study with Jon Wozencroftfrom, said: “We have had percussionists up here who have been able to actually get proper tunes out of the rocks. This is real rock music.”
This unique sonic nature could explain why neolithic men dragged the huge stones 200 miles from the Preseli Hills in Pembrokeshire, to Salisbury Plain in Wiltshire more than 4,000 years ago to build Stonehenge.
The exhibition will be the first to explain Stonehenge to visitors, with 250 prehistoric objects - many unseen before - on loan from various collections.
One highlight is the most advanced forensic reconstruction of an early Neolithic man's face, based on a 5,500-year-old skeleton buried in a long barrow 1.5 miles from Stonehenge.
Two rare 14th century manuscripts, including some of the earliest drawings of the monument, Roman coins and jewellery are also on display
The new facilities are housed in a pair of single-storey "pods", sitting beneath an undulating canopy that mimics the rolling plains nearby.
Further work to decommission the existing facilities, built in 1968, and returning the car park to grass will start in the New Year.
There is a 360-degree Stand in the Stones experience, using state-of-the-art laser scans, to allow visitors to experience summer and winter solstices.
A major exhibition will open for visitors tomorrow at the historic Stonehenge site.
ITV News got an exclusive look around the new visitor centre which includes important objects never seen before and a 360-degree experience that will allow visitors to 'stand in the stones'.
