Current ensemble forecasts from the Met Office and European models indicate overnight minimum temperatures in London on June 12 centered in the 14–17°C range, with 15°C and 16°C carrying the highest implied probabilities at 27% each. This positioning reflects mild maritime air advection, limited radiative cooling under expected cloud cover, and reduced nocturnal temperature drops compared to the June climatological average low near 12°C. Model spreads arise from uncertainties in boundary-layer moisture and wind patterns, which can shift the exact minimum by 1–2°C. Updated high-resolution runs and official guidance expected in the next 24–48 hours will likely refine these probabilities ahead of resolution.
