Highest temperature in Chengdu on August 4?

Platform comparison

Market context

Chengdu’s airport reading for 4 August is likely to land in the low 30s Celsius, with several August guides and forecasts pointing to a daytime high around 32–35°C and some risk of showers or thunder in the afternoon.[1][2][3][17] That leaves the market’s 0% YES pricing strikingly cautious against the broader seasonal picture: August is normally Chengdu’s hottest month, with long-run summaries putting typical highs near 30–32°C and some historical 4 August highs already above 32°C.[3][5][7][18]

For traders, the key catalyst is the day’s evolving airport observation, not a distant seasonal average, because the contract settles on the highest temperature recorded at Chengdu Shuangliu International Airport Station and can move on intraday highs before any evening cooling.[16] The main risk factor is whether cloud cover and rain suppress the peak into the low 30s, or whether a brief hot spell pushes it up towards 34–35°C as several forecast sources currently imply.[1][2][9][17] The market is therefore leaning most heavily on updated short-range forecasts and the live airport observation sequence, rather than on any scheduled political-style event.
