Highest temperature in Taipei on August 1?

Platform comparison

Market context

Taipei’s outcome will be set by the highest temperature logged at Songshan Airport on 1 August, and the crowd currently prices the market as if an extreme reading is unlikely: Polymarket shows 36°C as the leading bucket at 51%, with 37°C next at 32% and 38°C only 6%.[4] That distribution fits the local August climate, where Taipei typically sits in the low-to-mid 30s Celsius and can spike higher on very hot, humid days.[2][12][19]

For comparison, the more recent guide-style sources point to August highs around 33–34°C, but they also note that Taipei can reach the mid- to high-30s, and one reference cites a 38°C August peak in the past decade.[8][10][17] For this kind of market, Polymarket is quoted in implied probabilities, while Kalshi and Smarkets typically show market prices in their own contract formats and Betfair uses decimal odds, so the same weather view can look different even when the underlying expectation is identical; fees and access also vary, with KYC and geographic eligibility usually more restrictive on regulated books than on crypto-native venues.

The main catalysts are the day’s actual heat evolution, cloud cover, rainfall, and any typhoon-related disruption, because Taiwan’s August weather is often described as hot, wet, and storm-prone.[2][12][17] Traders should also watch the official forecast cadence from Taiwan’s Central Weather Administration and the final Wunderground history updates, since this market resolves off the day’s recorded maximum and Polymarket notes that revisions are only considered until the first datapoint for the following date is published.[4]
