Highest temperature in Shanghai on August 3?

Platform comparison

Market context

Shanghai’s outcome depends on the **highest recorded temperature at Shanghai Pudong International Airport Station on 3 August**, not the citywide average, so a brief midday spike or a localised hot spell is what matters most. Seasonal context points to a very warm early-August profile: AccuWeather shows Shanghai’s August highs typically around **82–92°F** (about **28–33°C**), with WeatherSpark putting the usual daily high nearer **85–90°F** and noting that extremes can still reach the mid-90s Fahrenheit. [1][11]

The current **0% YES** crowd price looks like a market that is treating a very hot reading as unlikely, but comparable Shanghai August forecasts often sit in the low-to-mid 30s Celsius, and some forecast services already show **33–35°C** for 3 August, with thunderstorm risk not necessarily capping the daytime maximum. [2][8][9] For a temperature market like this, the practical read is whether the airport station can print above the range implied by the broader forecast rather than whether Shanghai is simply “hot”; a one-degree shift can move the settlement band.

From a market-access perspective, the regulatory frame matters. In Germany, prediction markets can intersect with the GlüStV’s gambling perimeter if they are treated as games of chance rather than pure financial speculation, so availability may depend on how the operator classifies and localises the product. In the US, CFTC reach is the relevant issue if the market is offered to American users or resembles a derivatives contract on weather outcomes. If the venue advertises **“no-KYC up to $1,500”**, that usually means small deposits or withdrawals can be used with lighter identity checks, improving entry for casual users, but it does not remove geo-blocking, platform limits, or enhanced verification once thresholds are crossed.
