Recent Met Office guidance highlights building high pressure driving a warming trend across southeast England, with London forecast to reach 32°C on August 9 amid clear skies, light winds, and southerly warm advection. Ensemble models show modest spread around 29–33°C due to uncertainties in boundary-layer mixing and any residual cloud cover, while historical August maxima average near 22°C. The tight clustering of market-implied odds on 30–32°C reflects this consensus alongside recognition that small forecast adjustments—such as a delayed ridge or localized sea-breeze effects—could shift the peak by 1–2°C before resolution.
