Highest temperature in Guangzhou on August 15?

Platform comparison

Market context

Guangzhou's weather on 15 August 2026 will be assessed by the highest temperature recorded in the Daily Observations table at Baiyun International Airport Station, measured in degrees Celsius. The market currently shows 0% probability, suggesting traders expect temperatures to fall outside the upper range bands being offered. August represents peak summer in Guangzhou, with the city experiencing its most intense heat during this month, making extreme temperatures historically common rather than exceptional during this period.

Historical data from Guangzhou's meteorological records demonstrates that mid-August temperatures consistently exceed 33°C, with readings frequently reaching 35–37°C during typical summer conditions. The city's location in southern China's subtropical zone, combined with its proximity to the South China Sea, creates predictable heat patterns that have remained relatively stable across decades. Traders should note that the 0% probability reflects either the specific temperature thresholds being offered in the resolution brackets or a market expectation that August 2026 will deviate significantly from established norms—a scenario requiring either unusual atmospheric conditions or data recording anomalies.

The resolution methodology depends entirely on Weather Underground's Daily Observations table rather than summary figures, introducing a technical dependency that traders must verify independently. No scheduled weather events or climate anomalies have been forecast for August 2026 that would substantially alter Guangzhou's typical summer temperature range. Traders should monitor actual readings as the date approaches and cross-reference multiple meteorological sources to validate the specific temperature brackets offered, given the market's reliance on a single data source for settlement.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

What resolution source is used for elections?

Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.

Why do Polymarket and Kalshi differ on elections?

Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
