Highest temperature in Tokyo on July 6?

Platform comparison

Market context

Tokyo is entering its peak summer heatwave, with July 2026 already recording temperatures exceeding 36.8°C at multiple observation points across the nation, including a new record of 41.2°C in Tamba City. The market currently assigns a 0% probability to the highest temperature being 19°C or below, reflecting the overwhelming consensus that mid-July in Tokyo routinely reaches 36°C to 40°C with humidity levels above 95%, turning the city into a concrete jungle.

Historical data from the past three decades shows July average temperatures in Tokyo are 2.16°C higher than normal, with over 120 heatstroke-related deaths recorded in a single July, confirming that sub-20°C outcomes are virtually impossible during this period. Comparable cases from recent years, including Japan’s highest-ever temperature of 41.2°C in 2025, frame the current 0% probability as a rational assessment of extreme seasonal conditions rather than an outlier prediction.

Traders should monitor the Japan Meteorological Agency’s daily heat warnings and any scheduled climate declarations from the government, as these catalysts directly influence temperature forecasts and public safety advisories. Recent news from the agency confirms that 271 observation points exceeded 35°C on Wednesday alone, with new highs recorded in 39 locations, indicating the market is leaning heavily on immediate heatwave intensity rather than long-term climate trends.

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events.

How accurate are political prediction markets?
