Highest temperature in Taipei on August 10?

Platform comparison

Market context

Taipei’s hottest reading on 10 August will be set by a single station value at Songshan Airport, and the market resolves from Weather Underground’s *Daily Observations* table rather than the summary high/low box, so late-afternoon spikes matter more than the headline forecast. Recent forecast pages put Taipei around the low-to-mid 30s Celsius for the day, with one source showing 32.6°C and another 34°C, while climatology for early August commonly sits near 33°C, which is consistent with the market’s current crowd view being concentrated in the mid-30s rather than extreme heat.[2][5][10][11]

That makes the present 0% YES pricing on Polymarket hard to read as a true meteorological call; on the exchange-style book it reflects the absence of support at the listed strike, whereas on Kalshi or Betfair the same event would typically be expressed as a contract price or decimal odds, making a “0%” display less comparable across venues. The broader weather record also points to a wide but not exceptional distribution: Taipei’s August highs usually cluster around 33–34°C, with record highs well above that, so a 35°C-plus outcome is plausible but needs a strong daytime heating run or a brief break in cloud and showers.[2][3][11][15]

Traders should watch for the day’s actual convective-rain timing, because afternoon thunderstorms can cap the station maximum even when the morning starts hot; AccuWeather currently flags a thunderstorm around the afternoon, and Timeanddate shows a showery, humid profile with high humidity and only modest wind.[7][10] On platform mechanics, Polymarket charges no spread but does require on-chain settlement access, while Kalshi’s regulated US access and fee structure differ from Betfair or Smarkets, where commissions and KYC availability vary by jurisdiction; for a niche temperature market like this, those frictions can affect liquidity more than the weather itself.
