Highest temperature in Guangzhou on July 7?

Platform comparison

Market context

Guangzhou on 7 July 2026 is set to experience peak summer heat, with the Guangzhou Baiyun International Airport Station likely recording daily highs near 32–33°C, consistent with long-term July averages. The current crowd-implied probability of 0% YES for any specific temperature range suggests the market views the outcome as too uncertain or the range too narrow to warrant confidence, despite historical patterns showing highs rarely falling below 30°C or exceeding 36°C in mid-July.

Historical data from Weatherspark confirms that July daily highs in Guangzhou cluster around 32.8°C (91°F), rarely dipping below 29.4°C (85°F) or surpassing 35.6°C (96°F), with the highest average occurring on 25 July [1]. A recent Polymarket trade on 3 July 2026 resolved YES for a 34°C peak, indicating that temperatures in this range are plausible and not anomalous, even if the market currently assigns low probability to any single band [2][5]. This precedent frames the 0% probability as a reflection of market caution rather than physical impossibility.

Traders should monitor Wunderground’s hourly updates for the Baiyun station on 7 July, as real-time data will determine the final resolution [6]. Additionally, watch for official announcements from China’s National Meteorological Centre regarding heatwave intensity, which could shift expectations if temperatures breach 35°C—a threshold linked to record-breaking summer days in Guangdong since 1961 [3][7]. No major weather disruptions are forecast, but sudden thunderstorms, common in July, could temporarily suppress peak readings [4].

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.

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.

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.

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.
