Official Met Office guidance points to a maximum of 22°C in London on August 24 under mostly dry conditions with sunny intervals and moderate easterly winds of 10–15 mph. This aligns with the market’s leading 22°C and 21°C outcomes, which together capture over 80% of trader sentiment. The narrow spread reflects typical model uncertainty in peak timing and any late-day cloud buildup that could shave 1°C off the high. Late-August climatology supports readings near 21–23°C when high pressure dominates, with current guidance showing no significant Atlantic influence or showers to suppress temperatures. Updated model runs and any shifts in wind direction or insolation will be the key near-term variables traders watch.
