Highest temperature in Taipei on August 18?

Platform comparison

Market context

On 18 August 2026, the highest temperature recorded at Taipei Songshan Airport Station will fall into one of several defined ranges measured in degrees Celsius. The market resolves using the Daily Observations table from Weather Underground rather than summary figures, a distinction that matters when intraday peaks diverge from reported highs. The settlement window closes at 12:00 UTC on that date, meaning traders must account for the full calendar day's temperature swing across Taiwan's capital region.

Taipei's August climatology shows consistent heat stress, with historical daily maxima typically ranging from 32–35°C during this period. The 0% crowd probability suggests either extreme confidence in a specific temperature band or sparse trading activity. Comparable August temperature markets in East Asian cities have resolved across narrow ranges; Taipei's monsoon season variability and urban heat island effects mean afternoon peaks often exceed morning forecasts. Recent years' data from the Central Weather Administration indicate occasional excursions above 36°C during heat waves, though such events remain minority outcomes.

From a regulatory standpoint, this market's accessibility depends on jurisdiction and stake size. Under German GlüStV rules, prediction markets require licensing; UK-domiciled traders face no blanket prohibition but must verify their platform's regulatory status. US CFTC oversight applies to derivatives on event outcomes if US persons participate; many platforms enforce geo-blocking. The "no-KYC up to $1,500" threshold cited by some operators means traders can place modest stakes without identity verification, though this varies by operator and does not override CFTC or local financial crime rules. Traders should confirm their platform's compliance posture before committing capital.
