Highest temperature in Tokyo on August 13?

Platform comparison

Market context

Tokyo's peak temperature on 13 August 2026 will be measured at Haneda Airport Station and recorded in Weather Underground's Daily Observations table, settling the range that captures that single highest reading in degrees Celsius. The settlement window closes at midday UTC, meaning traders must account for the full calendar day in Tokyo (UTC+9) before the market locks.

August temperatures at Haneda have historically ranged between 28–36°C during the peak summer period, with extremes occasionally breaching 37°C during heat waves. The current 0% crowd probability suggests either insufficient market depth to establish pricing or genuine uncertainty about which temperature band will resolve. Comparable August days at Haneda over the past decade show that 32–35°C is the modal outcome, though the Japan Meteorological Agency's seasonal forecasts for 2026 remain unavailable until closer to the date. Historical volatility in late-summer Tokyo readings means traders should weight both typical seasonal patterns and any anomalous atmospheric conditions reported in the weeks preceding mid-August.

The key catalyst is the JMA's official weather outlook, typically issued monthly and refined weekly as August approaches. Traders funding positions via Klarna or SEPA deposits should note that book depth often correlates with settlement certainty; thin liquidity here may reflect genuine forecast ambiguity rather than mispricing. Withdrawal rails including USDC settlement will matter for traders seeking to exit positions quickly if weather models shift dramatically in late July or early August.
