High pressure building over southern England is the main driver pushing London’s maximum temperature on August 3 toward the low 30s °C, with Met Office and BBC forecasts indicating 28–31 °C under sunny intervals and light easterly winds. Recent model runs show warm air advection from the continent combined with minimal cloud cover and dry conditions, consistent with the above-average summer temperatures already recorded in 2026. Small differences in afternoon cloud development or exact wind direction between ensemble members account for the tight market split between 30 °C and 31 °C, while climatological August averages near 22 °C highlight the anomalous warmth. Updated short-range guidance and any late adjustments to boundary-layer mixing will be the next key data points before resolution.
