Current forecasts from the Met Office and BBC Weather indicate a high of 22°C for London on August 22 under sunny intervals and light northerly winds, aligning with the seasonal average and placing the outcome at the center of trader pricing. Model consensus supports this range after earlier August warmth, with minimal frontal activity expected to limit variability, though small differences in cloud cover, timing of any weak trough, or localized heating could shift the peak by 1°C. Ensemble spreads in global models reflect this tight clustering around 21–23°C, explaining the balanced market-implied odds and the premium on precision near the climatological baseline rather than extremes.
