The Met Office issues an extreme heat warning for Wales for the beginning of next week, with temperatures expected to rise rapidly. Multiple reports say some areas could see temperatures around 30°C early in the period, with one forecast indicating peaks of about 31°C in at least one part of Wales on Tuesday. The warnings are based on projected weather maps for the coming days and reflect unusually high temperatures for the time of year. The Met Office advises that conditions may become hazardous and that people should take precautions during hot weather, particularly during the hottest parts of the day. Sources consistently link the warning to the same outlook period and forecast pattern, describing sustained heat across parts of Wales rather than brief peaks. Overall, the reporting focuses on the likelihood of extreme temperatures, including mid-30s in some places, and the need for public awareness and preparedness as the heat arrives.
