Recent forecasts from the Met Office and BBC Weather indicate peak temperatures of 25–26°C for London on June 16 under settled high-pressure conditions with sunny spells and light westerly breezes. Ensemble model guidance shows limited spread around these values, reflecting modest uncertainty in afternoon insolation and boundary-layer mixing. Above-average June warmth follows a warmer-than-normal early summer pattern, yet no strong heat advection or clear-sky amplification is projected to push readings toward 27°C or higher. Traders assign nearly equal weight to 25°C and 26°C because small shifts in cloud cover or wind speed—common variables in short-range guidance—can move the daily maximum across that threshold, while lower outcomes remain less likely given the current ridge.
