Trader consensus on Polymarket heavily favors mild highs of 14–16°C for London's March 24 peak temperature, driven by the latest ECMWF and UK Met Office ensemble forecasts converging on 15°C amid a high-pressure ridge ushering Atlantic mild air. This setup overrides typical March averages around 11°C, with recent model runs showing reduced spread after initial cooler GFS outliers warmed up. Differentiating factors include potential cloud breaks boosting 16°C via enhanced insolation, versus partial overcast capping at 14–15°C; urban heat island effects at Heathrow (the resolution site) add 1–2°C. Uncertainty lingers from frontal timing, but odds reflect 90% confidence above 13°C per official outlooks.
