Britain has been battling scorching weather with record-breaking temperatures exceeding 30C (86F) across the country. The pattern has extended across Europe, with France and Spain experiencing extreme heatwaves and even wildfires. But holidaymakers might need to pack extra suncream and sun hats, as experts warn temperatures could rise to 50C (122F) this summer. This week is already forecast to be concerningly hot across Europe and some areas are set to continue to be uncomfortably warm over the summer.Professor Bill McGuire, a professor of geophysical and climate hazards at University College London, told The Telegraph that '50C (122F)-plus is perfectly possible later this summer'.He said: 'The record currently is 48.8C in Sicily in 2021, so it won't take much to beat this. If not this year, then 2027 is a good bet, as the influence of the building super-El Nino will be that much greater.'Inland southern Spain and Portugal are set to be 'the furnace of Europe this summer' according to Professor Hannah Cloke, a specialist in meteorology and climate science at the University of Reading. Metro passengers in Paris trying to keep cool during the most recent heatwave'Places like Seville and Córdoba, and inland Alentejo behind the Algarve, are likely to top 40C repeatedly over the next few weeks, with the low to mid 40s possible in the hottest spells,' she added. 'Sardinia has already been forecast to hit 43C this week. Rome and Florence are under Italy's highest heat alerts.'The meteorology expert notes Greece is set to reach 40C (104F) for the first time this summer over the weekend.Elsewhere, Professor Cloke said 'inland Turkey regularly pushes towards 45C in high summer.'She adds: 'Coasts and islands run a few degrees cooler, but even Mallorca has been in the high 30s. If you want guaranteed heat, book inland Andalusia. If you want to sleep at night, stay near the coast.'Meanwhile, Professor McGuire said he 'wouldn't touch anywhere in southern Europe' due to how hot the popular destinations are now getting.Professor Cloke predicts that 'High 40s are possible in the hottest spots, and where humidity is high it can feel hotter still.' Although she notes 50C (122F) is not yet in official forecasts for this season, she thinks: 'One of these summers, Europe will find out what 50 degrees feels like. I would rather we never did.'
