Recent forecasts from multiple models indicate the overnight minimum into September 1 will likely fall between 6–9 °C under partly cloudy skies and moderate northwest winds, with the daytime high reaching 12–14 °C. This range reflects uncertainty in nocturnal radiative cooling rates, boundary-layer mixing, and any late southerly wind shift that could import colder maritime air from higher latitudes. Clearer conditions promote greater surface heat loss and lower minima, while increased cloud cover or stronger winds limit cooling. Historical September climatology shows typical overnight lows near 8 °C, and the tight clustering of market-implied probabilities around 6–7 °C versus 12 °C or higher captures ongoing model divergence on exact wind speeds and cloud timing ahead of the 24-hour observation window.
