Highest temperature in Wuhan on August 10?

Platform comparison

Market context

Wuhan’s **highest temperature on 10 August 2026** will be judged from the Weather Underground **Daily Observations** table for the Wuhan Tianhe International Airport station, so the market is about the day’s peak reading rather than the summary “Day High & Low” figure. The current crowd-implied **0% YES** sits against a city where August is typically the hottest month, with average highs around **33–35°C** and historical daily highs often landing in the low-to-mid 30s Celsius. [4][5][6][10]

For comparable cases, Wuhan’s August weather history suggests that outcomes below **30°C** are possible but not the norm, while spikes into the **mid-30s°C** occur in hotter years; one historical set shows August highs of **36°C** in 2022 and 2024, alongside cooler August days closer to **31–33°C**. That makes the market’s current near-zero pricing look like a strong sceptical view on heat, not a statement that low temperatures are common. On Polymarket, the displayed market splits into discrete Celsius bands with implied probabilities; on Kalshi or Smarkets, the same weather idea would usually appear as a binary or price-quoted contract, so the same expectation can look very different once you convert between odds, probabilities, and fees. [7][9]

The main catalysts are the actual Wuhan airport observations through the settlement window, plus any shift in the local forecast from rain, cloud cover, or monsoon-type convection that can cap daytime heating. At 09:00 local time, one weather feed showed Wuhan at **27°C** with **patchy rain nearby**, a forecast high near **29°C**, and substantial cloud cover, which would matter if it persists into the afternoon. For platform comparison, Polymarket’s headline percentages can move sharply on small order flow, while Betfair and Smarkets usually show decimal prices and build in different commission or fee structures; KYC access also differs, with Polymarket, Kalshi, Betfair, and Smarkets all operating under different geographic and identity checks.
