Met Office and BBC Weather forecasts, updated early on April 17, project a maximum temperature of 17°C for London on April 18 under sunny intervals and light variable winds, aligning closely with trader consensus favoring 17°C at 43.5% implied probability and 18°C at 25%. This positioning reflects a cooling trend from early April's record 26.5°C heat on the 8th, as high-pressure influences weaken, introducing isolated light showers that could temper peaks, with feels-like temperatures around 15°C. Model consensus from numerical weather prediction systems shows minimal divergence for this short-range outlook, though urban heat islands and afternoon sunshine timing introduce ±1–2°C uncertainty. Hourly updates throughout April 17 will refine resolution odds based on official observations from sites like Heathrow.
