The UK's upcoming heatwave is set to bring a welcome change after a cooler June, but it's the difference from May's record-breaking temperatures that's intriguing. This weekend, temperatures will soar to around 30C, but it's the humidity that sets this heatwave apart. The warm air, influenced by continental sources, will create a muggy atmosphere, unlike the dry heat of May. This higher humidity will make the heat feel more oppressive, especially in southern England and Wales. The contrast between the two heatwaves highlights the dynamic nature of UK weather, where the same temperature can feel vastly different depending on humidity levels. It's a reminder that weather is not just about numbers but also about how it feels and the impact it has on our daily lives. As the UK basks in the warmth, it's a good opportunity to appreciate the small differences that make each weather event unique.
