Sun-soaked Brits have been warned they must never leave sunglasses on their dashboard after a pair set a car on fire this weekend.
Firefighters have said it is crucial reflective objects are not left in direct sunlight following the blaze.
The shades had been left out on a hot day and pictures show damage to the vehicle's steering wheel and a big hole in the windscreen.
Nottinghamshire Fire and Rescue Service said they attended the incident on Saturday as temperature soared to 24C in the afternoon.
With things set to heat up further, people have been told to be careful about the items left out on baking days and consider if they pose a danger.
They tweeted: "The sun has been strong but beware this can cause fire. Earlier we attended a fire caused by sunglasses left on the dashboard.
"Make sure you keep reflective objects out of direct sunlight."
The problems could only increase for the fire service with warmer weather coming out way.
After a wet and cloudy spring, Brits are start to see more blue skies and sun - and temperatures are about to spike further.
By early June, we could see the mercury hit 30C.
British Weather Services' senior meteorological consultant Jim Dale told the Mirror we'll need plenty of sunscreen in the days ahead.
"Definitely no records will be broken, but it'll be very warm toward the month's end and potentially nudging the 30C mark in the London area by June 5 or 6," he said.
"Before then, it could well be western Scotland that hogs the peaks of around 25C.
“There is a likely upper air drag out of North Africa around month’s end and we could well be in receipt of an ‘African Air-dryer’."
But he added: "One caveat, a change in the month means a change of weather. It'll be turning more humid with showery/thundery outbreaks increasingly likely into the south and west.
"We will no doubt pay for all this serenity somehow!"
Steven Keates, the Met Office's deputy chief forecaster said: "Next week is half term week for much of the country and there is as strong signal the high-pressure will continue to dominate our weather.
"Its exact position over the UK will dictate the temperature, wind direction and weather patterns, however, indications are that the dry, bright weather is likely to continue for most with little in the way of rain throughout next week."
