Recent meteorological forecasts from models including the Met Office and ECMWF indicate London’s overnight minimum on June 5 will register near 12°C under stable high-pressure conditions with light winds and limited cloud cover, aligning with early-June climatological norms of 10–13°C lows. This consensus has produced the market’s overwhelming 99.8% implied probability for exactly 12°C, reflecting traders’ assessment of verified observational data and minimal model spread. A realistic challenge would require an unexpected late-night radiative cooling event or rapid frontal passage that drops readings to 11°C or below, though current guidance shows no such shift before resolution at noon UTC.
