Recent short-range forecast guidance from the Met Office and European models shows London on track for a high of 22–23 °C on June 13 under partly cloudy skies, light northwesterly winds, and negligible precipitation. These conditions reflect typical early-summer radiative heating balanced by a cool Atlantic air mass, with limited diurnal range owing to residual cloud cover. Trader consensus clusters tightly around these values because ensemble spreads remain modest at two-day lead times, though small differences in simulated cloud timing or boundary-layer mixing can shift the peak by 1 °C. Updated model runs overnight and any Met Office briefing on frontal progression will be the next key inputs capable of moving implied probabilities.
