Trader consensus on Polymarket, with 23°C at 30.5%, 22°C at 27%, and 21°C at 21.5%, mirrors the latest Met Office forecast updated April 5 showing a 23°C high for London on April 8 under initially sunny skies turning to intervals, driven by a stabilizing high-pressure ridge ushering southerly winds and low rain risk (<5%). This follows early April's rainy start, with recent GFS and ECMWF runs converging on above-average warmth—well beyond the 13–14°C April climatological mean—due to clear skies maximizing midday solar insolation and subsidence suppressing clouds. Tight odds reflect 1–2°C ensemble spreads from model discrepancies in ridge positioning and afternoon cloudiness; daily updates from NOAA and UKMO through April 7 could refine trajectories, as short-range forecasts carry inherent uncertainty from evolving upper-air patterns.
