The Met Office forecasts that temperatures across the UK will rise next week, with some areas expected to approach 30°C. Multiple reports say the weather will shift toward warmer-than-expected conditions, describing high pressure building over the country as the main driver. Alongside higher daytime temperatures, the Met Office expects warm and humid nights, with conditions moving above the seasonal average. One outlet frames the forecast as the UK potentially becoming hotter than Los Angeles in temperature terms, reflecting the degree of warming expected during the period. Another report links the heat to the recent unusually warm start to the year, citing a record-breaking May heatwave in describing the broader pattern of higher temperatures. Overall, the sources agree the change is forecast to be driven by sustained high pressure, bringing higher temperatures and increased humidity rather than a single isolated spike.
