Highest temperature in Shenzhen on July 17?

Platform comparison

Market context

Shenzhen is currently under heavy rainstorm and thunderstorm activity, with the Shenzhen Meteorological Observatory upgrading rainstorm warnings to orange for Nanshan and Futian districts early on 17 July [5]. This wet, cloudy onset has suppressed daytime heating, keeping the forecast high at 31°C (86°F) with showers and a 70% precipitation chance through the morning [3][6]. The 0% crowd-implied probability for a high-temperature spike aligns with these conditions, as cloud cover and rainfall prevent the intense solar heating required for extreme heat.

Historically, July is Shenzhen’s hottest month, with an average high of 89°F (31.7°C) at Bao’an International Airport, but extreme peaks above 35°C typically occur under clear, dry skies [2][4]. Comparable cases in recent years show that when orange rainstorm warnings are active, daily highs rarely exceed 32°C, as the moisture and cloud layer act as a thermal buffer [5]. The current probability reflects this pattern: wet July days in Shenzhen consistently cap temperatures well below the thresholds that would trigger a “high” resolution.

Traders should monitor the Shenzhen Meteorological Observatory’s real-time warning updates and the timing of thunderstorm clearance, as a sudden shift to clear skies by midday could alter the heating trajectory [5]. The primary dependency is whether the rainstorm system dissipates before 14:00 local time, allowing solar radiation to drive temperatures upward; however, the 10-day forecast indicates continued light rain and overcast conditions through Friday [6][9]. Any official announcement lifting the orange warning or confirming a dry afternoon would be the key catalyst for a probability shift.

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 Prediction Today, which mirrors the Polymarket order book directly.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

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.

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.
