Highest temperature in Wuhan on August 11?

Platform comparison

Market context

On 11 August 2026, the highest temperature recorded at Wuhan Tianhe International Airport will determine this market's outcome. The settlement hinges on data from Weather Underground's Daily Observations table—the granular station-level readings rather than the rounded Day High & Low summary—ensuring precision in what is otherwise a straightforward meteorological measurement.

Wuhan's August climate is among China's most extreme. Historical data shows daily maxima routinely exceed 35°C during mid-August, with peaks near 40°C not uncommon. The 0% crowd probability suggests traders are either absent from this market or treating it as a certainty that temperatures will fall within a specific range. Comparable August forecasts for Wuhan over the past decade show little variance in whether heat thresholds are breached; the variance lies in which bracket—typically 35–37°C, 37–39°C, or 39°C+—captures the day's peak.

From a regulatory standpoint, this market's accessibility depends on jurisdiction. Under German GlüStV rules, prediction markets require licensing; traders in Germany face restrictions on unregulated platforms. US CFTC oversight extends to binary weather derivatives offered to US persons, though many platforms operate under exemptions for small-value contracts. The "no-KYC up to $1,500" threshold common on decentralised platforms means traders can participate without identity verification below that stake, though this does not exempt the underlying market operator from compliance obligations in their domicile. Wuhan's meteorological data is publicly available and uncontroversial as a settlement source, removing ambiguity that might otherwise trigger regulatory scrutiny.
