Recent Met Office and European Centre for Medium-Range Weather Forecasts ensemble runs place London’s May 19 daytime maximum in a tight cluster between 16 °C and 18 °C, explaining the near-even market split at 34 % each for the two leading outcomes. A mild south-westerly flow is expected to advect Atlantic air masses while variable cloud cover and light winds limit surface heating, keeping temperatures close to the mid-May climatological average of roughly 16–17 °C. Model spread arises mainly from uncertainty in the timing and extent of any sunny breaks versus increased low-level cloud, which could shift the official maximum recorded at London City Airport by one degree either side of 17 °C. With resolution just 48 hours away, traders are watching the next 12-hourly forecast updates for any tightening of guidance on solar insolation and boundary-layer mixing.
