Highest temperature in Tokyo on August 16?

Platform comparison

Market context

On 16 August 2026, the highest temperature recorded at Tokyo Haneda Airport Station will determine the settlement of this market. The resolution hinges on the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when intraday peaks diverge from headline highs. August in Tokyo typically sees temperatures between 28–35°C, though extreme heat events have pushed readings above 37°C in recent years. The 0% crowd probability suggests traders are either uncertain of the exact threshold bands or treating this as a calibration exercise ahead of the settlement window closing at noon UTC on the resolution date.

Historical August temperatures at Haneda show considerable year-to-year variation. In 2023, the station recorded a peak of 35.1°C; in 2022, 34.8°C. The Japan Meteorological Agency's heat advisories and the timing of any Pacific high-pressure systems will shape whether August 2026 tracks toward the cooler or hotter end of the seasonal range. Traders should monitor JMA forecasts released in early August and any alerts regarding potential heat waves across the Kanto region, as these typically precede extreme readings by 7–10 days.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under German GlüStV rules, prediction markets on weather events face stricter licensing requirements than political or financial derivatives. US CFTC oversight applies if the platform accepts US traders; most no-KYC markets cap participation at $1,500 per user to remain outside registration thresholds, though this limit does not exempt the operator from anti-fraud or market surveillance obligations. Traders should verify their local rules before entry.
