Highest temperature in Shenzhen on July 16?

Platform comparison

Market context

Shenzhen’s highest temperature on 16 July 2026 will be recorded at the Bao’an International Airport Station, with settlement tied to Wunderground’s daily maximum in degrees Celsius. On Polymarket today, the contract for any temperature range above the current implied threshold trades at 0% YES, reflecting a crowd view that extreme heat is unlikely despite July being Shenzhen’s hottest month. The market resolves on-chain using USDC on Polygon, where conditional tokens lock exposure until the 2026-07-16T12:00:00Z cutoff.

Historically, July in Shenzhen averages a daytime high of 32°C, with 17 rainy days and heavy precipitation from subtropical highs and typhoons dampening peak temperatures [1]. This pattern suggests that while 32°C is typical, sustained extremes above 35°C are rare due to frequent rainfall and cloud cover, which aligns with the 0% probability assigned to higher ranges. Comparable years show that even in peak summer, humidity and monsoon activity often cap maximums near the monthly average.

Traders should monitor the Guangdong Meteorological Bureau’s weekly typhoon and heatwave forecasts, as an approaching system could suppress temperatures further. A recent report from Travel China Guide notes that July’s average rainfall reaches 339 mm, reinforcing the likelihood of cooling showers [1]. Watch for any official announcements on extreme heat alerts before 16 July, as these would signal a deviation from the norm and potentially shift conditional token pricing on Polygon.

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 Kalshi UK, 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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi UK. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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'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.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi UK 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.
