Highest temperature in Guangzhou on July 25?

Platform comparison

Market context

Guangzhou will experience peak summer heat on 25 July 2026, with the highest temperature recorded at Baiyun International Airport Station determining the settlement outcome. Historical July maxima in Guangzhou typically range between 33–36 °C, though occasional heat waves have pushed readings above 37 °C. The 0% crowd probability suggests traders are either absent from this particular market or treating it as a placeholder pending clearer seasonal forecasting data closer to the date.

Comparable weather markets on prediction platforms show that summer temperature ranges in subtropical Chinese cities attract modest trading volume until approximately four to six weeks before settlement. Guangzhou's July climate is shaped by the East Asian summer monsoon and occasional tropical systems; the airport station's location in an urban setting means readings may differ slightly from rural zones. Previous years' data from Wunderground indicates that extreme heat events (above 38 °C) occur in roughly 15–20% of July days across a ten-year sample, providing a baseline for assessing tail-risk probability.

From a regulatory standpoint, this market's accessibility depends on the trader's jurisdiction. Under German GlüStV rules, prediction markets operating without a licence face restrictions on marketing to German residents. US CFTC oversight applies if the platform operates as a derivatives exchange; many prediction market operators structure themselves to avoid this classification. Platforms offering no-KYC access up to $1,500 USD typically do so under exemptions for small-value transactions, though this threshold varies by licence type and does not eliminate reporting obligations for the operator. Traders should verify their local rules before participation.
