Recent forecasts from models like those referenced by the Met Office and AccuWeather indicate overnight lows near 18°C for London on June 22, driven by high pressure promoting clear skies and moderate radiative cooling after daytime highs around 28°C. This aligns with climatological June averages of 11–17°C minima, tempered by urban heat retention and southerly flow. Trader consensus around 18°C (36.5%) and nearby values reflects model agreement on minimal cloud cover or frontal activity in the 48-hour window, though slight revisions in ensemble runs could shift probabilities toward 17°C if cooling strengthens. Historical precedents show June lows rarely dip below 15°C without significant Atlantic influence.
