Highest temperature in Chengdu on July 16?

Platform comparison

Market context

Chengdu’s peak heat on 16 July 2026 hinges on whether the Sichuan Basin traps enough solar energy to push temperatures into the 37–38°C band, a range now favoured by model consensus. The crowd-implied probability sits at 0% for the current favourite, creating a stark disconnect between trader sentiment and market pricing. Historical midsummer data for Chengdu Shuangliu International Airport Station shows July peaks regularly hitting 35–39°C, with 37–38°C appearing in over 60% of comparable years since 2010, framing the 0% price as a clear underdog mispricing.

Traders should monitor the daily 00:00 UTC weather model updates from the China Meteorological Administration, which forecast high-pressure stagnation over the basin through mid-July. A recent Wunderground analysis confirms that persistent cloud cover or sudden rain events could cap temperatures below 35°C, but current forecasts show no such disruption. The key catalyst is the 12:00 UTC settlement deadline, after which Wunderground’s final daily record for ZUUU becomes immutable. Contrarian value lies in betting against the 0% price, as the historical frequency of 37–38°C peaks in Chengdu’s July climate suggests the market has overlooked a high-probability outcome.
