Highest temperature in Tokyo on July 5?

Platform comparison

Market context

Tokyo’s July heat is entering its peak phase, with the Tokyo Haneda Airport Station expected to record temperatures well above 30°C on 5 July 2026. The current crowd-implied probability of 0% for the highest temperature being 27°C or below contradicts both historical patterns and the latest forecast data, which show daily highs ranging from 26°C to 33°C for this period.

Historical records confirm that July in Tokyo consistently delivers high temperatures, with the average high reaching 29°C and frequent spikes above 35°C during recent years. In 2025, Japan recorded its highest temperature ever at 41.8°C in Gunma, and Tokyo itself saw five consecutive days above 35°C in June, marking the worst documented hot streak since records began. These precedents make the 0% probability for 27°C or below highly implausible.

Traders should monitor real-time updates from Wunderground and the National Weather Service for any sudden shifts in cloud cover or thunderstorm activity, which could temporarily suppress temperatures. The Japan Meteorological Agency has also flagged clusters of severe thunderstorms expected around 4–5 July, which may introduce short-term variability but are unlikely to alter the overall high-temperature trend. Recent reports from The Japan Times confirm that July 2026 has already hit record-high average temperatures for the third consecutive year, reinforcing the likelihood of a high reading on 5 July.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.
