Highest temperature in Shanghai on July 8?

Platform comparison

Market context

Shanghai’s subtropical monsoon climate delivers scorching July days, with temperatures routinely exceeding 35°C and peaking around 3 PM. On 8 July 2026, the Shanghai Pudong International Airport Station is forecast to reach 36°C under scattered clouds, a figure consistent with recent daily highs that have climbed from 34°C on 6 July to 37°C on 7 July[6]. This upward trend aligns with long-term averages showing July highs increasing by 5°F over the month, rarely falling below 24°C but often surpassing 35°C[1][3].

Historical patterns strongly support the current 0% YES probability for any outcome below 30°C, as July daytime temperatures in Shanghai consistently hover above this threshold, frequently breaching 35°C[3][7]. The market’s near-certainty for higher ranges mirrors Polymarket’s 97% confidence in a 28°C overnight low for the same date, confirming that even minimums remain elevated in this humid season[2]. Traders should monitor Wunderground’s real-time updates for 8 July, particularly any sudden shifts in cloud cover or precipitation that could temporarily suppress peak heat, though early July 2026 data shows no such cooling events[6]. No major weather advisories or infrastructure disruptions have been announced that would alter the forecast, leaving the 36°C projection as the most reliable baseline for settlement[3].

FAQ

Are prediction markets better than sports betting?

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.
