Highest temperature in Shenzhen on August 9?

Platform comparison

Market context

Shenzhen’s high on 9 August is shaping up as a straightforward heat market rather than an extreme-temperature outlier. Private forecasters cluster around the mid-30s Celsius, with estimates ranging from 34°C to 36°C and official-style forecasts from Hong Kong’s observatory putting Shenzhen at 28–35°C under cloudy conditions.[4][14][15][8] AccuWeather is marginally hotter on the headline high at 98°F, while Weather Underground’s own resolution source will matter more than any summary panel elsewhere if a late-day spike or airport-station reading differs from the broader forecast picture.[1][20]

The 0% crowd-implied YES price makes sense only if the market is being read as a narrow temperature band rather than a simple “hot day” call. Comparable August climatology for Shenzhen usually sits in the low- to mid-30s Celsius, with monthly guides and historical normals pointing to highs around 32°C to 35°C and persistent humidity rather than a clean ceiling at one exact number.[18][13][15] That leaves the most relevant question as whether the airport station can print 34°C, 35°C or 36°C in the Daily Observations table, not whether the city feels oppressive overall.[20][5]

The key catalysts are the hourly evolution of cloud cover, any afternoon thunderstorm, and whether rain cools the airport enough to cap the day’s top reading. AccuWeather currently flags “partly sunny, then mostly cloudy with a thunderstorm around” and a 55% chance of precipitation, which would favour a lower peak if convection arrives early; if the strongest heating comes first, the day can still reach the upper-30s Fahrenheit-equivalent forecasts being shown elsewhere.[1][3] Traders should watch the Weather Underground hourly feed and the Daily Observations table at Shenzhen Bao’an International Airport, since the market resolves on that observed maximum rather than a forecast high.[20]

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.
