Highest temperature in Taipei on July 1?

Platform comparison

Market context

The crowd-implied probability of 0% for any specific outcome on this market appears to be a data error or misalignment, as real-time trading on Polymarket shows a clear consensus favouring 36°C at 37% and 35°C at 35%[1]. This sharp divergence suggests the current 0% figure does not reflect the collective view of traders who have actively priced in late-June heat trends, with the market opened just two days prior on 29 June[1].

Historically, Taipei Songshan Airport experiences its peak summer heat in early July, with daily highs averaging 30°C (86°F) and frequently reaching 33°C (91°F) during the hottest spells[5][6]. In July 2026, forecasts indicate highs ranging from 88°F to 98°F (31°C to 37°C), aligning closely with the market’s leading outcomes of 35°C and 36°C[3]. The 0% probability likely stems from a technical glitch rather than a genuine belief that temperatures will fall outside these ranges, given that summer averages consistently sit between 26°C and 33°C[5].

Traders should monitor the Central Weather Administration’s 72-hour forecasts for Taipei/Songshan Airport, which update daily and will signal any sudden shifts in cloud cover or precipitation that could suppress temperatures[8]. Recent weather patterns show a 70% chance of thunderstorms on 29 June with highs of 91°F, but a return to predominantly sunny conditions by 16 July with highs of 95°F (35°C), indicating a volatile but warming trend[2]. The key dependency is the timing of the next rain event; if the forecasted showers clear before 1 July, the 36°C outcome becomes highly probable, whereas persistent rain could cap temperatures near 34°C.
