Highest temperature in Shenzhen on July 20?

Platform comparison

Market context

Shenzhen is experiencing a sweltering, humid day with current temperatures around 31°C and a RealFeel exceeding 40°C, driven by high humidity and strong sunlight. Despite today’s heat, the market assigns a 0% probability to any outcome above the lowest range, suggesting traders expect a dramatic cooling event or data anomaly before the settlement window closes at midday UTC on 20 July 2026.

Historical July highs at Shenzhen Bao’an International Airport typically exceed 33°C, with recent years recording peaks near 36°C under sunny conditions. The current 0% YES probability for higher ranges contradicts this pattern, implying the market is pricing in either a major weather system shift—such as the 90% precipitation chance forecast by meteoblue—or a potential data gap from Wunderground. Comparable cases show that when heavy rain or cloud cover arrives in late July, temperatures can drop to 24–29°C, aligning with the market’s frontrunner of 29°C at 100% probability [2].

Traders should monitor the hourly forecast for Shenzhen Bao’an, particularly the 70% chance of showers in the coming hours and the near-90% precipitation probability over the week [3][4]. A sudden shift to clear skies tonight, as predicted by WeatherCrave with temperatures dropping to 13–18°C, could signal an unusual overnight cooling trend that persists into tomorrow’s settlement period [5]. Any official Wunderground update showing a lower daily maximum before 12:00 UTC will confirm the market’s current pricing.

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'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.
