Highest temperature in Guangzhou on July 1?

Platform comparison

Market context

Guangzhou on 1 July 2026 will see its peak temperature recorded at the Baiyun International Airport Station, with the market currently assigning zero probability to any outcome above the lowest range. This near-certain dismissal of higher temperatures contradicts the city’s well-documented climatic behaviour, where July is consistently the hottest month, averaging highs of 33°C (91°F) and rarely dipping below 29°C (84°F)[1][2]. Historical data reveals that 1 July 2004 saw Guangzhou reach 39.1°C—the highest ever recorded in the city—on exactly this date, suggesting that extreme heat on 1 July is not anomalous but historically plausible[4].

Traders should monitor real-time updates from Wunderground, the official resolution source, as well as regional weather bulletins from China’s National Meteorological Centre, which may issue heat warnings ahead of the settlement window[5]. Recent national trends show China experienced its hottest July on record in 2024, with average temperatures eclipsing previous decades, indicating a warming baseline that could elevate 2026’s peak[3][6]. While cloud cover and rainfall are common in Guangzhou during July, with monthly rainfall averaging 233mm, sudden shifts in monsoon patterns or reduced precipitation could allow temperatures to spike unexpectedly[2]. No official announcements have yet confirmed a heatwave, but the absence of such warnings does not rule out extreme conditions, especially given the 2004 precedent.

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.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

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.
