Recent ensemble forecasts from Taiwan's Central Weather Administration and global models such as ECMWF and GFS indicate peak daytime temperatures in Taipei on May 18 will likely reach 31–32°C, driven by a strengthening subtropical ridge promoting clear skies, strong solar insolation, and efficient boundary-layer heating amid moderate southeasterly flow. These conditions align with mid-May climatology, where typical maxima hover near 29–30°C but can exceed 32°C under suppressed convection. Key uncertainties differentiating nearby outcomes include the timing and extent of afternoon sea-breeze advection or localized cumulus development, which could cap readings at 30–31°C, versus drier mid-level air allowing brief excursions to 33°C or higher. Updated model runs and official observations through evening will refine these thresholds ahead of market resolution.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Taipei Songshan Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/tw/taipei/RCSS.
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 can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
