Trader consensus on Polymarket heavily favors a 14°C high in London on April 13 at 32.5% implied probability, closely trailed by 13°C (24.5%) and 15°C (22.5%), mirroring the Met Office's midday April 11 forecast update projecting a 14°C maximum amid sunny intervals and light showers. This tight clustering stems from ensemble model uncertainty over cloud cover and frontal shower timing during peak afternoon heating (2-4pm), when rain probabilities hit 50%, potentially capping insolation and temperatures below 15°C or allowing brief sunny breaks to push higher. An active jet stream maintains mild Atlantic air masses consistent with April's climatological mean high of ~14°C, though blustery winds add variability. Watch for ECMWF and Met Office revisions this afternoon refining the outlook.
