Recent Met Office guidance and ensemble model runs indicate a minimum temperature near 18–19°C in London on August 26, driven by persistent high pressure, light winds, and limited cloud cover that reduces nocturnal radiative cooling. Trader consensus clusters tightly around 17–18°C because small forecast differences in boundary-layer moisture, overnight cloud thickness, and the exact timing of any Atlantic front can shift the low by 1–2°C. Historical August minima average 14–15°C, but the current warmer-than-normal pattern and high-pressure dominance support the elevated probabilities for the upper end of the distribution while leaving room for modest downward revisions if clearer skies develop. Updated model runs and official minimum-temperature observations will be the next key catalysts.
