Highest temperature in Tokyo on July 27?

Platform comparison

Market context

Tokyo’s highest temperature is usually decided by a narrow band of summer heat rather than an extreme one-off spike, and late July sits squarely in the city’s warmest part of the year. Typical July daily highs in Tokyo are around 27–30°C, with highs often reaching the low-to-mid 30s and only rarely pushing much beyond that range.[3][4] For 27 July specifically, the current forecast points to a high of **33°C** in Tokyo, with cloud cover, some sunshine, and a risk of evening rain and thunderstorms.[1]

That makes the market’s current **0% YES** price easy to read as a demand for a very low threshold rather than a call on the weather being cool. In comparable Tokyo July conditions, 33°C is a credible outcome but not an especially hot one by midsummer standards, so the exact settlement band matters more than the headline number.[3][4] Forecasts that sit near the low 30s tend to leave the market vulnerable to small upward revisions, but they also leave plenty of room for a high that falls just short of the relevant range.[1][3]

The main catalyst for traders is the evolution of the day’s official forecast at Tokyo Haneda Airport, especially whether the afternoon heat builds before cloud and rain arrive later on.[1] Thunderstorm timing, sea-breeze effects, and any morning cloud thickness can all affect the final maximum, so intraday updates from the forecast source matter more than the seasonal average. If the expected high stays pinned around 33°C, the market remains sensitive to even modest revisions, while a hotter update would immediately move probability towards the next temperature band.[1][3]

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.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
