The UK has been sweltering in a heatwave this week, with more record-breaking temperatures predicted today. One man who moved to the UK from Florida has said even he wasn't prepared for the intensity of the heat10:47, 25 Jun 2026Updated 10:47, 25 Jun 2026When it comes to blazing sunshine and scorching temperatures, the American state of Florida is renowned as a place where you can stroll around in shorts and flip-flops throughout the year. Even in January, average temperatures are around 16 degrees - a level we'd consider quite pleasant here in the UK.‌Yet one man who relocated to Britain from the Sunshine State has admitted that even he wasn't braced for the full impact of the sweltering heatwave we've been experiencing this week.‌It's been utterly roasting across the UK this week, with temperatures forecast to reach 40 degrees in certain areas on Thursday. Brett, who, along with his UK-born wife Gemma, moved from Florida to Britain, highlighted one particular thing that left him completely gobsmacked about the heatwave.‌Brett, who co-hosts the YouTube channel How Great is Britain alongside Gemma, shared his experience in a TikTok clip. "A few months ago, my wife and I moved from Florida to England, and you would think that this type of heat that we're experiencing - again - in England, would be somewhat second nature or normal to us," he said. "But it is absolutely not."He went on to say: "What I'm realising is, part of moving internationally is having new experiences. One of my new experiences was just getting into the car, sitting down on the seat, touching the steering wheel, and making a noise that I have never, ever made before in my life. I can't even recreate it."Content cannot be displayed without consent‌Describing the noise as "completely involuntary", he went on: "It just came out of me. I didn't know that I could make a sound like that. But that's what this heat does. It is crazy intense."He wrapped up by saying he was "about to melt". "So if you're in this heat, if you're under this dome like I am, stay cool out there," he added. "It is a scorcher."When will the heatwave end?The Met Office's red heat warning runs until midnight today (Thursday), with overnight temperatures not set to drop below 20 degrees in numerous locations. That said, relief is approaching, reports the Express.‌The Met Office stated: "Thursday will see the peak of the heat for many, though those further east will retain extreme heat on Friday and Saturday and could continue to see further impacts, which has resulted in Amber warnings. The far southeast will retain the warmth the longest, though there should be a climb-down in figures by Saturday, with peaks around 32 degrees likely."Next week is likely to see a change to more of a westerly influence on the UK's weather, with a return to more average temperatures for the time of year and a mixture of winds and rain, particularly for those in the North West."Meanwhile, certain parts of the country are braced for torrential downpours and thunderstorms on Friday. Wales is set to bear the brunt of the rainfall, with heavy showers battering Cardiff from 2am, before pushing northwards into England until around 6am.Article continues belowScotland will see a swathe of rain cutting through its centre and across Fort William at 2.15am, subsequently sweeping further north.
