Highest temperature in Taipei on July 27?

Platform comparison

Market context

Taipei’s hottest reading on 27 July will be set by the maximum temperature logged at Taipei Songshan Airport Station, so the practical task is to map the day’s thermal ceiling rather than the afternoon average. In late July, Taipei is normally a hot, humid summer environment, with July highs often around the low 30s Celsius and frequent rain, so a finish in the 33–36°C band is the natural comparison range for this contract.[2][3]

The current crowd price is concentrated around **35°C** and **36°C**, with 35°C leading at 31%, which implies traders expect a fairly warm but not extreme outcome.[1] For a programme trading this market, the useful framing is to model it as a threshold problem: ingest the airport station’s hourly observations, watch the daily high as it updates, and compare any forecast shift against nearby buckets rather than treating the market as binary.[1] A zero-priced YES on the market as a whole would be a data anomaly in this setup, because the contract resolves to one of eleven temperature outcomes rather than a single yes/no event.[1]

The main catalysts are routine meteorological ones: cloud cover, rainfall timing, and whether a hot inland air mass or afternoon convection suppresses the peak at the airport site. July in Taipei is typically wet and changeable, so traders usually watch the morning sounding, local radar, and any forecast updates that affect the odds of a brief spike above 35°C before storms or sea-breeze effects cap the high.[2][3] For automated execution, the key dependency is the resolution feed itself: once the Wunderground station record prints a final maximum for the day, the market should be compared directly against the published Celsius bracket.
