Recent Met Office guidance points to an 18°C overnight minimum for London on July 6 amid building high pressure and a warming trend, with daytime highs reaching 32°C under sunny spells. This aligns with the market's leading 47% implied probability for exactly 18°C, as models show limited cooling overnight due to urban heat retention and light winds. Historical July lows average 13–15°C, but current conditions—driven by subtropical air advection—favor values near 18°C over cooler outcomes like 15°C (34%). Minor model spread around 16–20°C keeps those probabilities clustered near 33–34%, while extremes remain discounted absent major forecast shifts before resolution.
