Highest temperature in Chongqing on August 4?

Platform comparison

Market context

Chongqing’s **highest temperature** at the airport station on 4 August will be set by the warmest reading recorded that day, with settlement tied to Wunderground’s daily history page for Chongqing Jiangbei International Airport. In practical terms, this is a single-day heat event market, so the key question is whether the station logs a peak in the low 30s Celsius or pushes into the much hotter mid- to upper-30s range, which is what usually drives bracket outcomes in summer heat markets.

August is typically the hottest month in Chongqing, with climate guides pointing to average daytime highs around 34°C and frequent very hot days above 40°C, alongside high humidity and regular rainfall. Comparable August summaries for the airport area show forecast highs in the mid-to-upper 30s Celsius, while some sources still centre the city’s average high nearer 34°C; that gap matters because airport maxima can land above the city average if sunshine and local heating hold through the afternoon[1][6][13][15]. In other words, the crowd-implied 0% YES looks like a pricing artefact rather than a statement that a hot outcome is impossible, especially if the market’s YES side represents a high temperature band.

For traders, the main catalysts are the day’s actual airport observations, cloud cover, and whether rain arrives before the peak heat window. August guidance for Chongqing repeatedly shows a mix of heat and showers, and recent forecasts have kept 4 August around the mid-30s Celsius with patchy rain possible, which can cap the maximum if convection develops early[3][12][14]. On the funding side, markets like this often deepen when deposits are cheap and fast enough to support quick re-risking: Klarna and card on-ramps tend to matter for small, frequent top-ups, while SEPA and USDC rails usually support larger balances and faster redeployment, both of which can tighten spreads around weather releases and intraday temperature moves.
