Highest temperature in Chengdu on July 31?

Platform comparison

Market context

The event is the **highest temperature recorded at Chengdu Shuangliu International Airport Station** on 31 July 2026, measured in Celsius and resolved against Wunderground’s daily history page. The current crowd-implied **0% YES** suggests the market is pricing the listed outcome as effectively unavailable at present, but that should be read against the fact that Chengdu routinely sees late-July daytime highs in the low-to-mid 30s °C, with some forecasts putting the day near 33–35°C and occasional hotter spikes in the broader regional weather record. [2][3][8][10]

Historically, Chengdu’s July weather is shaped by heat, humidity and frequent rainfall, which can cap maxima but does not prevent short-lived warm breaks; several weather sources still show highs around 33–38°C for late July in the city. That matters for reading a temperature-range market because a single airport observation can settle into a different bracket from the broader city forecast, especially if cloud cover or showers trim the afternoon peak. In regulatory terms, access can vary: a German-facing user may find GlüStV rules relevant if the market is treated as gambling-like locally; in the US, the CFTC’s reach is broader where derivatives-style event contracts are offered to US persons; and “no-KYC up to $1,500” usually means a user can transact or withdraw up to that cumulative value before identity checks are required, which makes the market easier to access but not unrestricted. [3][7][16][19]

For traders, the main catalysts are the day’s live weather evolution at Chengdu Shuangliu: morning rain, afternoon clearing, wind shifts and humidity all affect the eventual high, and the settlement source is the airport station rather than a city average. Weather forecasts for Chengdu on 31 July 2026 have varied across providers, with some showing light rain and highs near 30–33°C, while others show warmer intraday peaks, so a late change in cloud cover or convective rain remains the key dependency.

FAQ

Do I need to KYC for Polymarket Legal UK?

Not for lifetime trading volume under $1,500. Above that threshold, a quick KYC flow kicks in — ID, selfie, approximately 5-10 minutes. The threshold matches FATF travel standards for unregulated crypto platforms.

Can I trade anonymously?

Pseudonymously, yes — up to the KYC threshold. Polymarket Legal UK stores an email address and wallet addresses rather than a legal name. Over $1,500 lifetime volume triggers KYC, after which identity is no longer anonymous.

What happens during a tax audit?

You're responsible for documenting your trades. Polymarket Legal UK exports a full transaction history (CSV/PDF) for tax reporting. In an audit you'll need to present these documents.

Is there a withdrawal cap?

No platform-side cap. You can withdraw any amount provided KYC is complete. SEPA bank withdrawals over €15,000 trigger additional anti-money-laundering checks (statutory obligation for all platforms).

What if regulation changes?

If regulation changes in your jurisdiction (e.g. prediction markets are banned), Polymarket Legal UK would geo-block the affected region and continue processing withdrawals. Your funds remain withdrawable at any time.
