Highest temperature in Guangzhou on August 1?

Platform comparison

Market context

Guangzhou’s outcome is driven by the highest reading at Baiyun International Airport on 1 August, and the market is effectively asking whether that station posts a daily peak above the current low-implied band. August climatology is strongly seasonal: multiple weather references put Guangzhou’s average August high around 33°C to 34°C, with very warm, humid conditions and frequent rain, while some historical August days have reached the mid-to-high 30s Celsius.[1][5][19][20]

A 0% crowd price is best read as an absence of buying interest rather than a true impossibility, because markets in weather contracts can stay pinned when the date is far off or when traders have not yet priced in local heat risk. On comparable Guangzhou climate data, the city regularly records August highs in the low 30s Celsius and can spike several degrees above average, so the settled range will depend on the single highest airport observation rather than the day’s mean.[4][5][20]

For accessibility, the key regulatory framing is that prediction-market access can vary by jurisdiction: German users face GlüStV-related restrictions on unauthorised gambling-style offerings, while US-facing venues must consider CFTC reach where contracts are treated as swaps or event-based derivatives. A “no-KYC up to $1,500” model typically means smaller participation is allowed before identity verification is required, which can make this specific market easier to enter at low size but does not remove geo-blocking, tax reporting, or local compliance constraints. Traders should also watch for late-day forecast updates around Guangzhou weather, airport observation timing, and any platform-side settlement clarifications, because the market resolves from the station’s recorded daily maximum on the relevant date, not from citywide averages.[12][18]
