Highest temperature in Shenzhen on August 3?

Platform comparison

Market context

The **highest temperature at Shenzhen Bao’an International Airport on 3 August** is being priced off a market that currently gives **0% to YES**, so the crowd is effectively treating the listed outcome range as unlikely. The underlying weather setup still looks summer-hot rather than cool: model and guide-style forecasts for Shenzhen point to highs around **31–34°C** today, with humidity and showers or thunderstorms a recurring feature, which can cap the upside if cloud cover or rain arrives earlier than expected.[3][9][11][17]

For a handicapper, that makes the current favourite a *broadly warm but not extreme* outcome, with the consensus sitting around the low-30s Celsius rather than a heat-spike or a cooler washout. Historical August climatology for Shenzhen is consistent with that read: average highs are commonly cited near **31–32°C**, with lows around **27–28°C**, and August is also described as a month with heavy humidity and a higher typhoon or rain risk.[17][19][20] That leaves value, if any, in contrarian tails rather than the centre of the distribution — especially if traders think the airport station gets a more marine-moderated reading than city-centre forecasts suggest.

The key catalysts are the day’s *actual convective rain profile* and any typhoon-related changes, because those can shift the daytime maximum materially even when the broader forecast stays hot. Shenzhen’s summer weather is often shaped by a rainy season running from May to September, with showers and thunderstorms common, so intraday cloud build-out or precipitation timing is more important than the headline daily high alone.[20][17] For this market, the settlement source is the Wunderground history page for Shenzhen Bao’an International Airport, so the practical watchpoint is the maximum observed temperature there before the settlement cut-off rather than any citywide forecast print.[6]

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Who Will Win, which mirrors the Polymarket order book directly.

Resolution & payout

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
