Highest temperature in Chengdu on August 4?

Platform comparison

Market context

Chengdu’s highest temperature on 4 August will be set by the Chengdu Shuangliu International Airport Station reading, so the key question is whether the day tops out in the low 30s or pushes into the mid-30s Celsius. Seasonal guides place Chengdu in its hottest, most humid stretch in August, with typical daytime maxima around 30–32°C and frequent rain or scattered showers, while forecast pages for 4 August point to roughly 31–32°C with patchy rain and a chance of 32°C highs.[2][3][7][13]

That backdrop matters for interpreting a 0% YES price, because Chengdu’s summer climatology usually supports a broad cluster around 32–34°C rather than an outlier extreme, and recent market commentary has treated 34°C as a plausible modal outcome while 35°C remains a meaningful tail if sunshine holds longer than expected.[15][17] The practical friction here is on the funding side: if deposits are easy and fast through familiar rails such as Klarna, SEPA, or USDC, books tend to deepen more quickly, whereas slower on-ramp and withdrawal paths can suppress participation and leave prices more sensitive to small weather-model updates and late-day re-pricing.

The main catalysts are the afternoon heat trend, cloud cover, and whether showers arrive early enough to blunt the day’s peak, because even a short clearing window can lift the maximum several degrees above the morning forecast. Traders should also watch for updated local forecasts and any change in the airport station’s published observations, since settlement depends on the highest recorded value for the day and late revisions before the next day’s first datapoint can still matter.[17]
