Highest temperature in Taipei on July 31?

Platform comparison

Market context

Taipei is already trading like a **favourite** to post a very hot reading, but the market’s **0% YES** implies the crowd is effectively pricing in an outcome below the settlement band rather than a normal July peak. The real-world reference point is the highest temperature at Taipei Songshan Airport on 31 July 2026, and the consensus weather backdrop is for late-July heat rather than any meaningful cool-off; Taipei’s July averages sit around the low 30s Celsius, with typical highs near 33°C and historical extremes reaching about 38°C[2][4][6][10][11].

That makes the underdog case harder to defend unless rain, cloud cover, or a sea-breeze change knocks the day down sharply. Recent reporting shows Taipei has already been running above 36°C this week, with Focus Taiwan saying temperatures topped 36°C for a third straight day on Friday, which reinforces the warm-side bias rather than a surprise downside break[1]. From a handicapper’s angle, the consensus appears to be that heat is the default; the value question is whether the market has overreacted to a strict resolution source and range structure, since a single airport station reading can differ from citywide conditions. The contrarian angle is any afternoon convection or storm activity near Songshan that caps the day’s high before the settlement window closes, while the value spot remains on the warmest bands if the current heat holds through midday and early afternoon[1][2][6].
