Latest ensemble forecasts from the Met Office and global models indicate a maximum temperature near 22–23°C in London on September 1 under a predominantly westerly flow with high pressure ridging from the south. This setup favors near-normal early-September conditions, with moderate diurnal heating and limited cloud cover allowing peak readings in the low 20s Celsius. Trader sentiment clusters tightly around these values because minor differences in frontal timing, wind strength, or afternoon insolation can shift the daily high by 1°C. Longer-range signals of possible warmer spells remain too uncertain to influence near-term resolution probabilities.
