Recent high-pressure building over southern England has driven warm, dry southerly flow into London, with Met Office and ECMWF guidance showing daytime maxima stabilizing in the upper 20s °C for June 18. Model runs indicate limited cloud cover and light winds favoring peak readings near 27–28 °C, though slight variations in boundary-layer mixing or timing of any residual moisture could shift the daily high by 1 °C. These conditions contrast with earlier June averages near 20 °C and explain why trader-implied odds cluster tightly around 27–28 °C rather than cooler or hotter extremes. Updated forecasts released today will be the next key input before official Met Office verification.
