article: It may still be April, but Britain looks set to get an early dose of summer sun. Temperatures are due to rise throughout today peaking at 22C (72F) tomorrow. Not only will that be the warmest temperature recorded this year, but it will also surpass the average daytime temperature for August. That is 11C warmer than the UK April average and would beat the current 2015 high of 20.7C (69F) on Easter Sunday in Aboyne, Aberdeenshire. The 22C (72F) predicted in the South East on Friday is also better than the 18C forecast in Marbella, 16C in Rhodes, 10C in Istanbul and 16C in Malta.

Meanwhile the Department for Environment, Food & Rural Affairs has issued a warning to asthma sufferers of 'very high' air pollution tomorrow. Its warning for the far South East of England also states that adults and children with lung problems should avoid strenuous physical activity. Experts said locally-emitted pollution that would normally blow away will become trapped to the ground for longer, because there will be little wind. A Defra spokesman stressed the high pollution is not a direct result of the warm weather, but a mixture of factors including the arrival of Saharan dust. British Lung Foundation chief executive Penny Woods said it could 'put people living with respiratory conditions at risk of worsening symptoms'. Retailers have been stocking up on picnic food, with customers expected to head to beaches and parks for the last days of the school holidays.

Morrisons said it expects barbecue essentials to fly off the shelves, and Waitrose sold a week’s worth of barbecue fuel on Easter Monday. But anyone hoping to head further afield could find themselves stranded, as a French air traffic control strike has left airports in disarray. Forecasters expect the UK to see high temperatures until the weekend - while yesterday’s national maximum was 19.3C (67F) in Usk, South Wales. Clear skies, lengthening days and a warm mass of air from southern Europe will create glorious weather for the country as the sun shines through. The weather will stay mostly dry and sunny across the UK for the next few days, although some showers are expected from late tomorrow.

Air pollution levels tomorrow are forecast to be ‘very high’ in the far South East of England - potentially putting asthma sufferers at risk. The guidance from the Department for Environment, Food & Rural Affairs affects people on the Sussex coast in towns including Hastings, Bexhill and Eastbourne. ‘Adults and children with lung problems, adults with heart problems, and older people, should avoid strenuous physical activity,' it says. Meanwhile people with asthma ‘may find they need to use their reliever inhaler more often’. Defra said that conditions will see 'locally-emitted pollution become trapped to the ground, because there's not so much wind'. A spokesman told MailOnline: 'Basically we've seen local pollution and it's a mixture of that with some air coming in from the continent and a little bit of Saharan dust. It will just be on Friday that we see "very high" measurements, and it's due to clear up by 6am on Saturday.' Met Office meteorologist Dan Williams said: ‘We are looking at high temperatures for most days until the weekend.’ He added: ‘Friday is looking like the warmest day of the week - we may well see 21C (70F) or higher in London.’ England, Wales, Scotland and Northern Ireland each had their warmest days of 2015 over Easter, but those records could all be broken by tomorrow. The average UK temperature for April is 11.4C (52F) and for England is 12.4C (54F), according to the Met Office. Meanwhile safety charities warned people not to be tempted to swim in reservoirs or from unmonitored beaches during the warm weather. Some 400 people drown in the UK each year, the equivalent of one every 20 hours. In times of good weather drownings peak, charities said. And Morrisons said it expects barbecue essentials to fly off the shelves this weekend as the UK basks in some early spring sunshine. The Bradford-based retailer is predicting it will make and sell 1.4million fresh British beef burgers - a 30 per cent rise on last week. It also said sales of sausages made at its own manufacturing sites are expected to exceed 1million, while 1.6million burger buns will be baked. Morrisons added that this week it will sell half a million pegs and 62 miles of washing lines - enough to stretch from London to Cambridge. Waitrose said its rosé wine sales are up 24 per cent, strawberries are up 32 per cent, and a week’s worth of barbecue fuel was sold on Easter Monday. A spokesman added: ‘Shoppers are making the most of the change in temperature and stocking up on summery food and drinks.’ Reflection: A spring morning by Anish Kapoor's  Temenos sculpture, on the south bank of the Tees in Middlesbrough .

A spokesman for the supermarket added that sales of muffin tins have risen by a whopping 350 per cent, while dinnerware is up by 35 per cent. M&S said sales of its Grill range including burgers and ‘Posh Dogs’ are expected to rise by 30 per cent as people plan barbecues in the warm weather. A spokesman added: ‘It is expected that our prepared salads sales will increase by 35 per cent as people are looking for lighter options.’ Finally, Aldi said it expects sales of its premium Aberdeen Angus beef burgers to increase by 25 per cent as customers fire up their barbecues.
