Trader consensus on Polymarket closely splits between 15°C (39.5%) and 14°C (38.5%) as London's highest temperature on April 1, driven by the Met Office's latest forecast—updated 2:44pm March 31—projecting a 15°C maximum under overcast skies with low daytime precipitation risk (<10%). Persistent stratocumulus cloud cover limits solar insolation and diurnal heating, creating uncertainty in the exact peak; ensemble models like ECMWF and UKMO show a tight 14-15°C spread amid mild southerly flow from a weak high-pressure ridge. Above-average for early April (historical Heathrow mean ~12°C), but full cloud deck favors the lower end unless brief breaks emerge. Watch evening Met Office update and Heathrow observations for resolution shifts.
