Highest temperature in Taipei on July 22?

Platform comparison

Market context

Taipei Songshan Airport is already in a hot, humid regime, so the question is whether the day’s peak lands in the low-to-mid 30s or breaks higher. At 9am UTC, AccuWeather had the airport at 88°F with a RealFeel of 103°F, 71% humidity, and cloudy skies, which fits a live environment where the official maximum can still move materially with afternoon sun and local sea-breeze effects.[2]

The crowd is pricing a very specific outcome: 36°C at 93%, with 37°C or higher at 5%.[1] For programmatic traders, that means the cleanest approach is to map each Celsius bucket directly to the Wunderground daily high for RCSS and treat the market like a threshold problem rather than a point forecast, because the settlement depends on the single highest observed temperature on the day rather than the noon reading or a daily average. July is also Taipei’s hottest month on average, with daytime highs around 34°C, so 36°C is already close to the seasonal centre of gravity and 37°C requires only a modest overshoot from typical summer conditions.[3]

For catalysts, the key inputs are the afternoon heating profile, cloud break-up, and any change in wind or convection around Songshan Airport, all of which can change the final reading even if the morning looks uniform. A practical workflow for bots or conditional orders is to watch the Wunderground station page through the afternoon, compare it with nearby official observations, and update exposure only when the intraday trend shows whether the day is tracking below or above the 36°C band; with the settlement window ending at 12:00 UTC, the final print is likely to be set by Taiwan daytime conditions already in progress rather than late-night drift.
