Highest temperature in Shenzhen on June 4?

Market context

Shenzhen's maximum temperature on 4 June 2026 will be recorded at Bao'an International Airport Station and resolved against historical Weather Underground data. Early June in Shenzhen typically sees daily highs between 28–32°C as the city transitions into the pre-monsoon season, though heat waves occasionally push readings above 35°C. The 0% crowd probability suggests traders are either absent from this contract or treating it as a placeholder pending seasonal forecasts closer to the resolution date.

Historical precedent shows Shenzhen's June temperatures cluster predictably: the past decade's early-June readings at Bao'an rarely exceed 33°C on typical days, with extremes above 36°C occurring roughly once per five-year cycle during anomalous heat events. The current zero probability reflects the market's inability to distinguish between temperature ranges when no consensus forecast exists; comparable weather markets on other Chinese cities show similar flatness six months ahead of resolution.

Traders should monitor China Meteorological Administration seasonal outlooks, typically released in April, which will signal whether June 2026 is forecast as warmer or cooler than the 30-year normal. El Niño or La Niña conditions developing through early 2026 will influence monsoon timing and intensity, directly affecting Shenzhen's maximum temperatures. Real-time divergence between sportsbook weather derivatives (if available) and this market's ranges will emerge only once April forecasts materialise; until then, the 0% reading reflects genuine absence of actionable information rather than bearish sentiment.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.

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

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
