توقع: Highest temperature in Shanghai on August 8?

Platform comparison

Market context

Shanghai’s 8 August reading is usually a hot, humid one, with August norms clustered around the low 30s Celsius and daytime highs commonly in the 32-35°C range. Recent historical guides for the city put the monthly average high at about 32.5°C, while day-specific climate tables for 8 August commonly show a normal high around 33°C, with recorded extremes stretching into the high 30s[1][3][8]. That makes a settlement band above 35°C plausible in a strong heat spell, but the market’s current 0% YES price implies traders are not expecting an extreme enough reading to land in the top bucket.

For comparison, Shanghai’s August record highs have reached around 40°C in some datasets, but those are outliers rather than the base case[1][2]. The key trading point is that the market resolves off the Weather Underground Daily Observations at Shanghai Pudong International Airport, not the headline day-high summary, so small intraday differences matter if the station briefly spikes after the summary figure is posted[5][12]. With the settlement window ending at 12:00 UTC, the relevant watchpoint is the final observed maximum on Weather Underground rather than any later city-wide estimate or forecast.

Catalysts are limited this late in the day, so the main drivers are whether Shanghai gets deeper sunshine, a weaker sea breeze, or convective cloud and rain that caps the airport maximum. Weather Underground’s history page already shows the airport site and the daily record format that will decide the market, and current historical context places early-August Shanghai in a heat-prone part of the monsoon season[5][10][16]. If the morning starts close to 30°C and humidity stays high, a modest rise into the mid-30s is feasible; if cloud or rainfall develops, the highest temperature can be pinned nearer the low 30s and keep the settlement away from the upper ranges.

What's the difference between match odds and outright odds?

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
