Highest temperature in Taipei on August 20?

Platform comparison

Market context

On 20 August 2026, the highest temperature recorded at Taipei Songshan Airport Station will fall within 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 headline highs. Taipei's August climate is characterised by monsoon influence and urban heat effects; historical August maxima at Songshan typically range between 33 and 37 degrees Celsius, though extremes have occasionally exceeded 38 degrees.

The 0% crowd probability reflects genuine uncertainty about which specific temperature band will capture the day's peak. August in northern Taiwan sits within the summer monsoon season, when afternoon thunderstorms can suppress temperatures or, conversely, when high-pressure systems drive sustained heat. Comparable August days at Songshan over the past decade show considerable variance: some years peak near 35 degrees amid cloud cover and precipitation, whilst others reach 37–38 degrees under clear, stagnant conditions. No single outcome dominates the probability space, which explains the flat distribution across available ranges.

From a regulatory standpoint, this market operates under differing frameworks depending on trader jurisdiction. UK-based traders should note that prediction markets fall outside FCA direct regulation if structured as peer-to-peer wagering; however, German traders face scrutiny under GlüStV (Glücksspielstaatsvertrag) rules, which classify weather derivatives as gaming unless they meet specific financial instrument criteria. US CFTC reach extends to binary options on weather indices if marketed to US persons. Most platforms offering no-KYC access up to $1,500 USD do so under exemptions for small-value contracts; this market's accessibility without identity verification depends on the hosting platform's jurisdictional registration and whether the contract size remains below relevant thresholds.

UK Frequently Asked Questions

Is Polymarket legal in my country?

Polymarket is geo-blocked in the US/UK/EU. Actual usage via the Polymarket interface is not possible there. The legal status itself varies — many countries treat prediction markets as a gray area. Polymarket Tax UK has a different geo footprint.

Is Polymarket regulated by the UKGC?

No. Polymarket is not licensed by the UK Gambling Commission (UKGC). It is a decentralised prediction market operated under US regulation. UK traders can use it but do not benefit from UKGC dispute resolution or player protection requirements.

What are the HMRC tax rules on Polymarket profits for UK traders?

Polymarket profits are treated as cryptocurrency disposal events by HMRC. Each USDC settlement is a taxable event subject to Capital Gains Tax (CGT).
