Recent Met Office observations and forecast models indicate London temperatures stabilized near 15°C as the daily minimum on June 12, with daytime peaks reaching the low 20s under a mix of clear spells and light winds. This aligns with seasonal norms for early June and the influence of a weakening high-pressure ridge limiting further nocturnal cooling. Trader consensus at 99.5% for 15°C reflects real-time surface data and model agreement from agencies like the Met Office, with minimal deviation expected overnight. Unlikely shifts could arise only from rapid advection of cooler maritime air or localized radiative cooling under unexpected clear skies, though current conditions and timing make these outcomes improbable before resolution.
