**Trader consensus at 100% implied probability for a 30°C high in Taipei on September 16 reflects real-time observations and model runs showing a daytime peak of exactly that value.** Central Weather Administration and international forecasts (including hourly data from sources like Yr) indicate temperatures climbed to 30°C around midday under partly cloudy skies with light easterly winds and moderate humidity, consistent with late-summer subtropical conditions and no significant frontal activity or enhanced convection to push readings higher or lower. Historical September averages for Taipei hover near 30–32°C, providing climatological support. Because the market resolves on official maximum readings, scenarios that could still alter the outcome remain limited to post-peak measurement revisions, station-specific microclimate differences, or rare data adjustments, though current convergence across models makes these low-probability events.
