Highest temperature in Tokyo on August 14?

Platform comparison

Market context

On 14 August 2026, Tokyo Haneda Airport Station will record its daily maximum temperature in degrees Celsius. This market resolves to the temperature range containing that single highest reading, sourced from Weather Underground's Daily Observations table rather than the summary Day High & Low section—a distinction that matters when intraday spikes occur outside typical peak-heat windows.

Tokyo's August climate is remarkably consistent year-on-year. Historical data from the Japan Meteorological Agency shows that mid-August highs at Haneda typically cluster between 32–35°C, with extremes rarely exceeding 37°C even during heatwave years. The 0% crowd probability suggests traders are pricing in either extreme confidence in a narrow range or genuine uncertainty about which specific band the market operator will define. Comparable August readings from 2020–2024 provide the most relevant baseline; 2023 saw several days above 35°C during a sustained heat event, whilst 2022 remained closer to 33°C average. The settlement window closes at midday UTC on 14 August, creating a hard cutoff that excludes any afternoon surge recorded after that moment.

Traders should monitor Japan Meteorological Agency forecasts released in early August 2026, particularly any alerts regarding high-pressure systems or typhoon proximity that could suppress or elevate temperatures. El Niño or La Niña conditions active in mid-2026 will influence seasonal patterns. Under German GlüStV and US CFTC frameworks, weather derivatives of this specificity typically fall outside direct regulatory reach when structured as prediction markets under $1,500 per position; however, aggregate exposure across multiple temperature bands may trigger reporting thresholds depending on the operator's jurisdiction and customer base composition.
