This market will resolve to the temperature range that contains the lowest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 15 Apr '26. The resolution source for this market will be information from Wunderground, specifically the lowest temperature recorded for all times on this day by the Forecast for the Tokyo Haneda Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/jp/tokyo/RJTT. 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.Trader consensus on Polymarket has locked in 100% implied probability for a lowest temperature of 15°C in Tokyo on April 15, 2026, backed by Japan Meteorological Agency (JMA) observational data and forecast models showing the pre-dawn minimum holding steady at that level amid mild spring conditions. Overnight partial cloud cover and southerly flows under a weakening high-pressure ridge limited radiative cooling, keeping temperatures above the mid-April climatological normal of about 11°C, with no sharper drop observed at official stations like Tokyo or Haneda. Model ensembles from JMA and global forecasts align on this, with current midday readings already climbing to 20°C+. Realistic challenges would require an anomalous late-night measurement revision or station-specific microclimate anomaly, both highly improbable given the day's progression and consistent hourly data. JMA's final daily summary, expected soon, will confirm resolution.
