Forecast models from the Met Office and others indicate predominantly sunny, high-pressure conditions over southern England on August 2, supporting daytime maxima centered on 26–28°C and positioning 27°C as the modal outcome. Persistent anticyclonic patterns this summer, combined with elevated North Atlantic sea surface temperatures, have sustained above-average warmth, while an emerging El Niño adds a modest global temperature boost. Light winds and clear skies limit cloud cover and enhance solar heating, though any unexpected frontal activity could trim the peak by 1–2°C. Traders assign limited probability to 29°C or higher given the absence of strong southerly flow, aligning with climatological norms for early August in London.
