Recent forecast models from agencies like the Met Office indicate above-normal temperatures across southern England through early August, driven by building high pressure that favors clearer skies and reduced radiative cooling overnight. This setup supports trader consensus around an 18°C minimum on August 3, with 19°C as a close second, as ensemble guidance shows limited cloud cover or wind to suppress lows further. Historical August baselines place typical London minima near 14–15°C, but current warm anomalies and light winds elevate the near-term outlook. Key variables include any last-minute shifts in pressure patterns or Atlantic fronts, with updated model runs expected daily ahead of resolution.
