Highest temperature in Beijing on July 12?

Platform comparison

Market context

Rain and heavy precipitation have dominated Beijing’s skies over the last 24 hours, suppressing any chance of extreme heat on 12 July 2026. Current hourly forecasts confirm heavy rain continuing through the afternoon at Beijing Capital International Airport, with a maximum temperature of just 31°C and 38mm of precipitation expected [10]. This wet, cloudy pattern directly explains the crowd-implied 0% probability for any high-temperature range above the current forecast, as rain clouds and high humidity prevent the surface heating required for record highs.

Historically, July is Beijing’s hottest and wettest month, with temperatures often reaching 40°C during dry heatwaves, but such extremes are rare when precipitation is active [2]. In comparable cases where heavy rain coincided with mid-July, daily highs rarely exceeded 32°C, aligning with today’s 31°C forecast [9]. The 0% probability reflects this established climatic dependency: without a rapid shift to clear skies and low humidity, the temperature cannot breach the upper ranges traders might otherwise consider in a dry July.

Traders should monitor the National Weather Service’s real-time station data for ZBAA, which updates every few minutes and will confirm if the rain persists or breaks [6]. Any sudden announcement of a weather system clearing before 12:00 UTC could alter the settlement, but current schedules show no such forecast change [10]. The key dependency remains the persistence of the heavy rain; if it continues through the settlement window, the market will resolve to the lower temperature range, validating the current 0% probability.

FAQ

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

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 Prediction Today trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

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.
