Britons are basking in sweltering sunshine ahead of the hottest day of the year.
Temperatures reached the high 20s while forecasters said the mercury would soar to 30C (86F), prompting bookmakers to cut the odds of a record-breaking summer.
The hottest day of the year so far was May 24, when the mercury reached 28.8C (84F) at Heathrow Airport and the Olympic Park in east London.
Thousands made the most of the weekend heatwave, flocking to beaches and parks or soaking up the rays with barbecues in the garden.
By 2pm, the temperature had reached a high of 27.7C (81.9F) at Wisley in Surrey as large swathes of England got into the swing of summer, although western areas and Wales were experiencing slightly cooler weather.
The sweltering conditions come as millions prepare to watch England take on the arch enemy, Germany, in the World Cup, and Murraymania sweeps Wimbledon.
Thousands of revellers at Glastonbury music festival have also been able to ditch their wellies for the first time in years and party in the sunshine.
Ladbrokes offered 3/1, cut from 7/2, that the highest ever UK temperature of 38.5C (101.3F) recorded at Brogdale, near Faversham, Kent, in 2003 will be beaten.
Spokesman Nick Weinberg said: "We're feeling the heat as temperatures continue to soar."
William Hill meanwhile set odds of 16/1 that temperatures will top 100F (37.8C) at Wimbledon 2010 and 5/1 that the temperature will break the 100F mark at any time this year.
