Current weather forecasts from major models indicate a maximum temperature of 22°C in London on June 13 under stable high-pressure conditions with clear skies, light winds, and minimal cloud cover, aligning closely with typical mid-June averages of 19–21°C. This supports the market's strong consensus at 22°C, as official Met Office observations are expected to match the predicted peak without significant deviation from seasonal norms or anomalous warming. Realistic challenges include last-minute forecast revisions from updated model runs showing cooler Atlantic airflow or localized variations at monitoring stations, though current data shows low uncertainty in this range.
