Highest temperature in Shenzhen on July 6?

Platform comparison

Market context

The underlying event is the peak daily temperature recorded at Shenzhen Bao’an International Airport on 6 July 2026, measured in degrees Celsius and sourced from Wunderground. Historically, July is the hottest month in Shenzhen, with average highs around 89°F (31.7°C) and frequent peaks exceeding 92°F (33.3°C)[2]. Over the past decade, roughly a quarter of July days have seen highs below 87.1°F (30.6°C), but most days reach between 87.1°F and 91.4°F (30.6°C–33.0°C)[7]. Given this baseline, a current crowd-implied probability of 0% for any specific temperature range suggests either a mispriced market or an unusually narrow resolution band that excludes likely outcomes.

A programmatically inclined trader would monitor real-time inputs from Wunderground’s historical API and cross-reference with NOAA’s live time-series data for ZGSZ to validate anomalies[1]. Key catalysts include sudden shifts in monsoon activity, cloud cover density, or wind patterns that could suppress peak temperatures below historical norms. Recent forecasts indicate warm conditions with a maximum of 31°C on the afternoon of 5 July, suggesting continuity into 6 July[3]. Traders should also watch for official meteorological bulletins from China’s National Meteorological Centre, which may issue heat advisories or temperature corrections that directly impact settlement. No major weather disruptions are currently forecast, but rapid changes in tropical systems could alter the day’s thermal profile.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Bot UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
