Highest temperature in Taipei on July 22?

Platform comparison

Market context

Taipei’s hottest reading today is likely to land in the mid-30s Celsius, with the market currently pointing to **36°C** as the clear favourite. On Polymarket, that outcome is shown at **93% implied probability**, with **37°C or higher** at 5%[1]. On the underlying source market, the result is set by the day’s peak temperature at Taipei Songshan Airport, not a city-wide average, so a brief late-afternoon spike is enough to decide settlement.

That probability sits in line with Taipei’s July climate rather than an exceptional heat event. July is typically the hottest month in Taipei, with an average daytime high of about **34°C**, and temperatures often sit within a narrow band of roughly one to two degrees around that level[4]. With current conditions already very warm at the airport and forecast highs around 91°F, the main question is whether local heating and humidity can push the day above the usual mid-30s range[2][3].

For traders comparing platforms, the same weather contract can look different in presentation and execution. Polymarket quotes a simple implied probability, while Kalshi-style venues usually display decimal prices and may apply different fee and KYC rules depending on jurisdiction; Betfair and Smarkets typically add exchange commissions and require account verification before access. The practical catalysts are the midday and afternoon forecast updates, plus any local thunderstorm development, because convective cloud or rain can cap the day’s maximum even when the morning starts hot[3].
