Highest temperature in Shenzhen on July 13?

Platform comparison

Market context

Shenzhen is experiencing active monsoon conditions on 13 July 2026, with heavy rain and cloudy skies suppressing temperatures at the Bao'an International Airport station. Current hourly data indicates a maximum of 33°C is forecast for 14:00, though widespread precipitation and low cloud cover typically cap daily highs well below the extreme thresholds required for a "YES" resolution in high-temperature contracts [3][10]. The crowd-implied probability of 0% reflects this immediate meteorological reality, as the settlement window closes at 12:00 UTC, meaning the day’s peak temperature has likely not yet occurred or is already constrained by the storm system.

Historically, July is the hottest month for Shenzhen, with average highs reaching 31.7°C (89°F), yet record-breaking days exceeding 38°C are rare and usually occur under clear, dry heat domes rather than active rain [2][9]. Global temperature records from July 2024 set new benchmarks, but local Shenzhen data shows that monsoon-driven cooling frequently prevents temperatures from reaching the upper ranges needed for positive outcomes in similar weather markets [4]. The current 0% probability aligns with comparable cases where tropical rain systems override seasonal heat, making a high-temperature spike statistically improbable before the settlement deadline.

Traders should monitor the cessation of the heavy rain forecast for the morning and the potential for afternoon clearing, which could allow temperatures to rise toward the 33°C mark [10]. However, the settlement time of 12:00 UTC (20:00 local) falls before the typical daily peak, and the persistent cloud cover suggests the maximum will remain moderate. No official announcements or schedule changes are expected to alter this trajectory, as the resolution relies strictly on Wunderground’s recorded maximum for the station [1]. The divergence between the 0% market price and the theoretical seasonal average highlights the specific impact of today’s weather event rather than a broader consensus shift on Shenzhen’s climate.

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 Best Prediction Markets, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

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.

What does Polymarket cost to trade?

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Best Prediction Markets 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.
