Highest temperature in Guangzhou on August 1?

Platform comparison

Market context

Guangzhou’s airport temperature on 1 August will be set by the day’s *actual peak reading*, not by any citywide average or monthly norm, so the market is really asking whether the station posts an unusually hot afternoon rather than whether the day feels broadly summerlike. August is climatologically the hottest month in Guangzhou, with typical highs around 32–34°C and very humid conditions, so the settlement outcome will most likely sit in the upper part of the usual seasonal range rather than in a cooler band.[4][15][20]

That historical frame matters because Guangzhou’s summer heat is persistent but not flat: daily highs in August commonly cluster around 33°C, while especially hot spells can lift temperatures into the mid-30s and beyond.[1][4][20] That makes the current 0% YES pricing look less like a weather forecast than a statement about how the market has been framed, since a single hot afternoon is ordinary in this climate and historical comparables suggest the relevant question is whether conditions are merely seasonal or briefly extreme.[1][2][4]

The main catalyst traders should watch is the short-range forecast for Guangzhou Baiyun International Airport and any sign of a heat ridge or afternoon shower pattern, because cloud cover and rain can cap the day’s maximum while clear, humid air can push it higher. AccuWeather’s August 2026 outlook for Guangzhou points to daily highs mostly in the 89°F to 93°F range, which supports a warm baseline but leaves meaningful room for whether the airport touches the top end of the resolution bands.[12] For this market, the key dependency is the airport station’s reported daily maximum on Wunderground, so late updates in the local forecast carry more weight than broader province-level weather commentary.[13]

FAQ

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.

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.

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.

Which political events have the biggest volume?

US Presidential election, party nominations (DNC/RNC), Senate majorities, individual state outcomes (Pennsylvania, Michigan, Wisconsin), and major European elections. Peak markets reach $50-500M per event.
