Highest temperature in Guangzhou on August 14?

Platform comparison

Market context

Guangzhou will experience peak summer heat on 14 August 2026, with the market seeking to predict whether the highest temperature recorded at Baiyun International Airport will fall within a specific range. The resolution hinges on Weather Underground's Daily Observations table rather than summary figures, establishing a precise measurement standard that eliminates ambiguity between different reporting methods.

Guangzhou's August temperatures have historically clustered in the 32–35°C range, with occasional peaks exceeding 36°C during particularly intense heat waves. The city's subtropical monsoon climate produces consistent summer highs, though year-to-year variation remains modest. August 2023 saw daily maxima between 31–34°C, whilst August 2024 recorded peaks of 33–36°C. This historical pattern suggests traders should anchor expectations around the 33–35°C band as baseline, with extreme outcomes (below 30°C or above 37°C) representing genuine departures from typical conditions rather than routine variation.

The primary catalyst affecting this market's outcome remains atmospheric conditions in the weeks preceding mid-August 2026. Tropical cyclone activity in the South China Sea, monsoon intensity, and upper-atmosphere pressure systems will determine whether Guangzhou experiences typical summer heat or anomalous conditions. Traders should monitor meteorological forecasts from the China Meteorological Administration and international weather models approximately one to two weeks before the settlement date, as medium-range forecasts become sufficiently reliable for temperature prediction at that horizon. The current 0% probability assigned by the crowd likely reflects either an extremely narrow or implausible temperature range rather than genuine meteorological impossibility.

UK Frequently Asked Questions

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.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

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.

Are political prediction markets legal in my country?

It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.

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.
