Highest temperature in Shenzhen on July 27?

Platform comparison

Market context

Shenzhen Bao’an International Airport is in a hot, humid phase of the year, with current readings around 28–31°C and the broader July climate typically producing daytime highs near 32°C, alongside frequent rain and thunderstorms.[1][2][4][5] In that setting, the highest temperature on 27 July is more likely to land in the low-30s Celsius than to produce an extreme outlier, which helps explain why the market is still leaning towards the lower bands rather than a very hot tail outcome.[2][5]

The 0% crowd-implied YES price looks most consistent with a market that is being treated as a narrow temperature-range call rather than a directional weather bet, especially with the settlement tied specifically to the *day’s maximum* at the airport station and not to city-wide conditions.[2] Comparable Shenzhen July cases usually hinge on whether showers break up afternoon heating or allow a brief warm spike; with rain common and humidity high, the ceiling often depends more on short-lived clear spells than on any broad seasonal trend.[2][5]

For traders, the main catalyst is the live sequence of hourly observations and any shift in convective rainfall around the afternoon heating peak, because that is what determines the recorded daily maximum at Shenzhen Bao’an International Airport Station.[2] Short-range weather services currently show warm, humid, partly cloudy conditions with scattered shower risk, which supports watching whether the temperature briefly clears the low-30s Celsius or remains capped by cloud and precipitation.[3][6]

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.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

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.
