Highest temperature in Shenzhen on July 8?

Platform comparison

Market context

The real-world event centres on the highest temperature recorded at Shenzhen Bao’an International Airport on 8 July 2026, with current crowd-implied probability of 0% favouring the “YES” outcome. Historical data shows that early July in Shenzhen typically sees peak temperatures around 25.8°C to 30.9°C, with 8 July historically marking the lower end of the monthly range at approximately 25.8°C (78.5°F) [7]. Comparing this to July 2024 and 2025, both years recorded similar morning lows and modest highs, rarely exceeding 31°C at the airport station [5][8]. Given these patterns, the 0% probability aligns with expectations that extreme heat is unlikely on this specific date, especially when contrasted with global July records where Furnace Creek reached 42.5°C in 2024 [3].

Traders should monitor morning weather schedules for thunderstorms and rain, as AccuWeather forecasts morning rain and mostly cloudy conditions for 8 July, with temperatures peaking near 87°F (30.6°C) [2]. A heavy precipitation event exceeding 0.8 inches is predicted for Tuesday, which may suppress daytime highs further [1]. While no official announcements are pending, the dependency on Wunderground’s hourly data means traders must watch for real-time updates on cloud cover and wind gusts, which could influence the final reading. Recent reports of record-breaking heat in the US through 4 July highlight regional variability, but Shenzhen’s early July climate remains relatively stable, making extreme deviations improbable without a sudden shift in monsoon patterns [9].

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.
