After the damp and cool weather, the UK will see an Indian summer next week with temperatures well into the 80s.
By Monday, parts of the south could be warmer than the Portuguese capital, Lisbon, amid widespread sunshine in England and Wales.
London is expected to have a maximum temperature of 27 ° C that day, while many areas in southern England and east Anglia could reach 25 ° C.
Further north, the warmest places reach 22 ° C. Lisbon is only set to 23 ° C. The warm conditions are expected to last until next week.
The rising mercury will arrive over the weekend as large groups are allowed to gather for the last time before tighter restrictions are put in place. As of Monday, only six people are allowed to socialize together.

In its forecast, the Met Office said, “The period will likely change the weather in recent weeks.
"This calm weather should bring temperatures to near normal levels for most of the year, but the south could sometimes see warm or very warm temperatures."
With clear skies and light winds, widespread fog and mist will develop at night, especially in rural areas, forecasters say.
The Met Office adds that after several days of persistently warm weather, thunderstorms could also occur – especially for south west England.
Forecasters say they don't yet know how long the warm spell will last or when it will collapse.
But they predict a return to the usual sunshine pattern, mixed with autumnal wet and windy weather before the end of the month.
The Indian Summer should develop after mostly dry but cool days with cool nights.
Today is mostly dry with some sunny periods, while tomorrow there will be some clouds and showers – especially in the afternoon and especially in the northwest.
The temperatures from today to Saturday will only reach highs of 20 ° C in the south and 17 ° C further north.
The warmer weather is expected to kick in on Sunday, when the southeast of England is expected to hit 77 ° F (25 ° C). However, the very warm period that will hit the country in the next week is unlikely to break records.

The September temperature record in Britain dates back more than a century to 1906 when 35.6 ° C (96.08 ° F) was recorded at Hesley Hall near Bawtry, South Yorkshire.
The warmest day in September in recent years was September 13, 2016 when it recorded 34.9 ° C (93.9 ° F) in Gravesend, Kent – the warmest day of the year.
It comes after a mixed couple of weeks. There was a record-breaking heat wave in the first half of August, when temperatures hit 34 ° C or higher for six consecutive days, while the second half of the month saw the aforementioned storms Ellen and Francis and one of the coldest bank holiday weekends in August ever.
But the British will make the most of the weekend weather. It is the last time that large groups are allowed to socialize.
Cornwall, Devon and Dorset will prepare for a new influx of tourists as sun seekers flock to the white sandy beaches of the south west.
However, the local MPs and police seem to be welcoming vacationers and urging people to be vigilant and abide by social distancing rules.
East Devon MP Simon Jupp told MailOnline: “I am very encouraged by the continued low number of coronavirus cases in Devon and the South West, despite the number of visitors who provided much-needed cash flow for our economy.
“It's still important that people take personal responsibility for keeping themselves and each other safe – washing hands, covering your face indoors, and getting a test if you have symptoms.
& # 39; The new restrictions are easier to understand and easier to enforce. We should all do our part to fight the virus. & # 39;
Steve Double, MP for St. Austell and Newquay, said, “September and October are often the best times to visit Cornwall as the weather often stays fine even after school and people can enjoy our county beauty while it's a little less busy.
"My message to those looking to visit Cornwall before the excellent weather forecast for this weekend is that everyone is welcome as long as you act responsibly and respect and follow the latest government guidelines to ensure a safe vacation for locals and visitors alike."

North Devon MP Selaine Saxby added, “North Devon cases remain low this week and our tourism and hospitality businesses look forward to seeing visitors as they have subsided since the easing.
& # 39; The vast majority of our visitors were very strict with the guidelines. Outdoor transmission remains low and most travel to my constituency to enjoy the outdoors. & # 39;
A spokesman for the Dorset Police Department told MailOnline: “We are continuing to work with partners to ensure we have a detailed plan in place to handle the expected influx of visitors to our county during sunny periods.
“We are all very keen to welcome visitors to our area, but we want to make sure that people enjoy what Dorset has to offer in a safe, respectful and responsible manner, without putting additional strain on all emergency services and public resources. We want to remind people to adhere to government guidelines on social distancing. "
Boris Johnson yesterday insisted that Monday's draconian new coronavirus restrictions are essential to "keep our economies going and keep schools open".
The Prime Minister informed the House of Commons that with the surge in infections over the past week, he had no choice but to act.
And he warned the "rule of six" about how many people can socialize, "familiar with the country," which signals that the situation is unlikely to get better anytime soon.
In a major setback to his quest to get back to normal by Christmas, Mr Johnson has announced the first tightening of the national lockdown since March.
As of Monday, it will be illegal to gather in groups of seven or more across England, indoors or outdoors.
The limit sparked by concerns about partying young people causing a flare-up is a dramatic reduction from the July 4th maximum of 30.
It is enforced by the police with fines of £ 100, which double to £ 3,200 for each repeat offense. The only exceptions are schools, workplaces and a limited number of other locations.
