Latest numerical weather prediction models from the Met Office and European Centre for Medium-Range Weather Forecasts indicate a minimum temperature near 12 °C for London on 5 June 2026, following the cooler, unsettled pattern that replaced May’s heatwave. Overnight radiative cooling under partly cloudy skies and light winds supports this range, with ensemble guidance showing limited spread around 11–13 °C. Historical June climatology for central London places typical overnight lows at 11–12 °C, reinforcing the market’s heavy weighting toward 12 °C. Any shift in steering flow or increased cloud cover overnight could nudge the observed minimum slightly lower, but current consensus keeps probabilities for outcomes below 11 °C minimal.
