Recent Met Office forecasts highlight a strengthening high-pressure system and warm southerly flow driving an early-summer heatwave across southern England, with central London temperatures potentially peaking near 35–37 °C on June 24. Ensemble model runs show modest spread around these values due to uncertain cloud cover and boundary-layer mixing, while climatological baselines place average June maxima near 20–22 °C. The amber extreme-heat warning through mid-week and the proximity to the UK June record of 35.6 °C anchor trader focus on the 36–38 °C band, though any overnight cooling or Atlantic front arrival could cap readings at 35 °C or below. Updated guidance expected within 24 hours will further refine land-breeze and urban-heat-island effects.
