Highest temperature in Shenzhen on July 21?

Platform comparison

Market context

Shenzhen will experience peak summer heat on 21 July 2026, with the highest temperature recorded at Bao'an International Airport determining the settlement range. July sits within Shenzhen's hottest period, when the city's subtropical climate produces sustained high temperatures and humidity driven by the East Asian summer monsoon.

Historical records from Shenzhen Bao'an show July highs consistently exceed 32°C, with typical daily maximums ranging between 32–35°C during mid-to-late July. The airport station, located in the coastal Bao'an district, records temperatures slightly moderated by maritime influence compared to inland areas. Over the past decade, 21 July has seen highs between 31–34°C, though extreme heat events have occasionally pushed readings above 35°C. The 0% crowd probability suggests traders expect the market's lowest temperature bracket to capture the day's high, reflecting confidence in typical seasonal patterns rather than anomalous heat.

Traders should monitor weather forecasts released in the week preceding 21 July, particularly from the China Meteorological Administration and international models, which typically show skill 7–10 days ahead for East Asian summer temperatures. Any tropical cyclone activity in the South China Sea or unusual atmospheric blocking patterns could elevate temperatures above the seasonal norm. Real-time conditions on the day—cloud cover, wind direction, and monsoon intensity—will determine whether Shenzhen experiences a routine mid-summer high or an outlier reading. The settlement source, Wunderground's historical data from Bao'an, provides transparent verification against official meteorological records.

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.
