**Trader consensus strongly favors 21°C as the lowest temperature in Taipei on September 17, 2026, at 99% implied probability.** This reflects convergence across official forecasts and observational data pointing to a minimum near that threshold under stable subtropical conditions. September climatology for Taipei typically features overnight lows in the low-to-mid 20s °C, with radiative cooling under clear or partly cloudy skies allowing temperatures to reach 21–23°C before dawn. Current Central Weather Administration guidance and model runs show mostly clear to partly cloudy skies, light easterly or southwesterly winds, low precipitation probability (under 20%), and minimal moisture advection, supporting efficient nighttime cooling without significant cloud insulation or warm-air advection. Hourly trends from multiple sources indicate the daily minimum occurring in the pre-dawn hours around 21.4°C, consistent with historical analogs for similar synoptic patterns. Scenarios that could realistically shift the outcome include unexpected persistent low cloud cover or fog that limits radiative cooling, or a late-model revision showing stronger onshore flow. However, with multiple independent forecasts aligned and the day well underway, the market-implied odds capture the high-confidence scientific consensus on the likely minimum.

This market will resolve based on the lowest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the lowest temperature recorded at the Taipei Songshan Airport Station in degrees Celsius on 17 Sep '26.
The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day for the Taipei Songshan Airport Station, available here: https://www.wunderground.com/history/daily/tw/taipei/RCSS.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.**Trader consensus strongly favors 21°C as the lowest temperature in Taipei on September 17, 2026, at 99% implied probability.** This reflects convergence across official forecasts and observational data pointing to a minimum near that threshold under stable subtropical conditions.
