A mini spring heatwave is set to hit large areas of England this weekend, with temperatures forecasted to soar to 21°C in regions such as London, the South East, and East Anglia. Weather maps from WXCharts, based on Met Desk data, indicate that these warmer conditions will arrive on Saturday, April 25. The forecast suggests that London, Essex, Kent, and Hertfordshire could see highs of 20°C, while areas in the southwest, including Bristol and Devon, may reach 18°C to 19°C. Meanwhile, Wales is expected to experience temperatures between 16°C and 18°C, and northern England could see highs of 15°C to 18°C. Scotland will generally be cooler, with some western areas reaching 15°C or 16°C, but northern and eastern regions are likely to remain much chillier, with highs of only 6°C to 10°C. This warm spell follows a cooler and unsettled week, promising a more pleasant end to April for many. Notably, the UK temperatures will be warmer than Ibiza, where highs are expected to be around 20°C with a chance of rain. The Met Office has noted that the week has been largely settled with plenty of sunshine, and temperatures have been on the rise since the 17.1°C high recorded on Monday in Coton-in-the-Elms, Derbyshire.
