Highest temperature in Taipei on July 12?

Platform comparison

Market context

Taipei Songshan Airport is currently overcast with rain showers and an 88°F reading, creating a stark contrast to the market’s 0% implied probability that the day’s peak will breach typical July extremes. July is Taipei’s hottest month, averaging a 92°F high at this station, yet today’s cloud cover and 100% precipitation probability suggest the heat dome has collapsed [1][2]. Historical patterns show July 12s often hit 35–37°C, but the immediate weather system—rain showers forecast through 08:00 local time—acts as a natural thermostat, suppressing peak temperatures well below the 38°C threshold that would trigger a YES outcome [6].

The consensus leans heavily toward a cool, wet day, but value may sit in contrarian positions if the rain clears by afternoon, allowing solar heating to spike temperatures unexpectedly. Traders should monitor the Central Weather Administration’s hourly updates, particularly the apparent temperature reading of 35°C reported at 09:30 local time, which hints at residual heat despite the overcast [7]. A sudden drop in cloud cover or a wind shift could act as the catalyst for a late-day temperature surge, though current forecasts indicate persistent rain and 20 m/s winds limiting such a breakout [10]. The settlement window closes at 12:00 UTC, meaning any afternoon spike must occur before then to resolve the market.
