توقع: Highest temperature in London on August 19?

Platform comparison

Market context

On 19 August 2026, the highest temperature recorded at London City Airport will determine this market's resolution, with measurements taken from Weather Underground's Daily Observations table rather than the summary high-low figures. The settlement window closes at midday UTC on that date, capturing the full diurnal cycle through to the market's cut-off point.

London's August temperatures have historically clustered in the 20–27°C range, with extremes rare but not unprecedented. The city recorded 40.3°C in July 2022, though August typically runs cooler. Over the past decade, August highs at City Airport have exceeded 25°C roughly 60% of the time, with readings above 28°C occurring in fewer than one in five years. The 0% crowd probability suggests traders are pricing in either a notably cool August or uncertainty about the specific resolution mechanics tied to Weather Underground's data hierarchy.

Key variables affecting the outcome include Atlantic weather patterns in early August, which determine whether high-pressure systems establish over the UK or whether cooler maritime air dominates. The Met Office's long-range forecasts, typically issued in late July, will provide the first substantive signal for seasonal positioning. Any significant heatwave warnings issued in the fortnight before 19 August would sharply alter implied probabilities, as would persistent low-pressure systems driving cooler conditions. Traders should monitor European weather models from mid-August onwards, as the 10-day forecasts become reliable enough to price specific temperature bands with confidence.
