Highest temperature in Shenzhen on July 16?

Platform comparison

Market context

Shenzhen is experiencing rain and cloud cover at the Bao'an International Airport Station on 16 July 2026, with current temperatures around 27°C and a high chance of precipitation. This wet, overcast start suppresses the likelihood of extreme heat, aligning with the crowd-implied 0% probability for any high-temperature outcome in this market. The settlement relies on the day’s peak temperature recorded at this specific station, sourced from Wunderground history.

Historically, mid-July in Shenzhen often sees highs near 33–35°C, but cloud cover and rain significantly reduce solar heating. Comparable cases from recent years show that when precipitation exceeds 20mm and skies remain overcast, peak temperatures rarely exceed 30°C. The current 68–80% precipitation probability and heavy rain forecast (>0.8") suggest conditions will stay well below typical summer extremes, reinforcing the market’s low YES probability.

Traders should monitor hourly updates from AccuWeather and the full-day Wunderground record once the day closes, as sudden clearing could shift outcomes. No official announcements or schedules are pending that would alter weather patterns, but local thunderstorm activity remains the key variable. On platforms like Polymarket, this market displays as 0% implied probability, whereas Kalshi or Betfair might list it as decimal odds of 1.00, reflecting divergent pricing conventions. Fee structures and KYC requirements also vary: Polymarket is generally non-KYC with lower fees, while Kalshi mandates US residency and identity verification.
