Highest temperature in Tokyo on July 5?

Platform comparison

Market context

The underlying event is the peak daytime heat expected at Tokyo Haneda Airport on 5 July 2026, where meteorological records will determine if temperatures breach a specific Celsius threshold. Historical data from AccuWeather indicates Haneda’s July highs typically range from 26°C to 33°C (76°F to 91°F), with an average of 29°C (85°F)[1]. Comparable cases from recent summers show that while extreme spikes above 35°C are rare, the current crowd-implied probability of 0% YES suggests traders view a breach of the market’s upper range as statistically negligible, aligning with Agate Travel’s observation that daytime temperatures remain stable around 28–33°C during Japan’s plum rainy season[4].

Traders must monitor real-time atmospheric dependencies, including the intensity of the sea breeze and the progression of the plum rain front, which can suppress peak temperatures. A recent forecast from the National Weather Service recorded a high of 34°C (94°F) on 4 July at Haneda, indicating volatility that could shift probabilities if similar conditions persist into the settlement day[2]. Key catalysts include official weather bulletins from the Tokyo Metropolitan Government and Wunderground’s hourly updates, which serve as the definitive resolution source for this market[1].

Accessibility for this market is shaped by regulatory frameworks, notably Germany’s GlüStV and the US CFTC’s reach over prediction contracts. The “no-KYC up to $1,500” provision allows traders to participate without identity verification for stakes below this limit, enhancing liquidity for retail participants while maintaining compliance with anti-money laundering standards. This structure ensures the market remains open to a broad audience without compromising legal safeguards under international tax and KYC regimes.
