Highest temperature in Taipei on August 10?

Platform comparison

Market context

Taipei’s afternoon high on 10 August is the relevant live variable here, with the market resolving from Weather Underground’s **Daily Observations** for Taipei Songshan Airport Station rather than any headline “Day High & Low” figure. Seasonal baselines put early August in Taipei around the low-30s Celsius, with common forecasts clustering near 32–34°C and occasional higher spikes; AccuWeather and other climate guides show today’s forecast broadly in that band, which makes the upper-30s outcomes the key tail risk rather than the central case.[1][2][3][5][7]

On comparable summer days, the market has tended to price a heat-up rather than a cooling surprise because Taipei’s urban heat, humidity, and late-day convective thunderstorms can push the official daily maximum after a hot morning. That is why a 0% crowd-implied price can be misleading on a platform comparison: on Polymarket, the quoted probability is the market’s own share price; on Kalshi, the same event would usually be expressed as a contract price; Betfair and Smarkets instead surface decimal-style pricing, and their net return is further shaped by commissions or fees. Access also differs materially, since KYC and jurisdictional reach vary across these books, which affects who can trade and at what speed.

The main catalysts are the day’s actual temperature path and the timing of any thunderstorm or rain band, because a brief afternoon storm can cap the maximum even after a hot morning. AccuWeather’s Taipei forecast points to a p.m. thunderstorm risk today, while timeanddate and other forecast services also show a showery, humid setup, so traders should watch whether the airport station reaches its peak before cloud cover and rainfall develop.[7][10]

Which platform has the deepest liquidity?

Polymarket — by a wide margin. Top markets reach $50-500M volume, Kalshi ~$200M cumulative, Betfair similar. Deeper liquidity means your trade moves the quote less.
