Trader consensus assigns a 100% implied probability to a lowest temperature of 17°C in Tokyo on May 3, driven by Japan Meteorological Agency (JMA) observational data confirming an early-morning minimum of 17°C at key stations amid a stable high-pressure system. Partly cloudy skies, light winds around 5-10 km/h, and urban heat island effects have prevented further radiational cooling, with afternoon temperatures climbing to 23°C. This aligns with above-normal May patterns, where historical daily minima average 14-15°C but current model ensembles from JMA and global forecasts like ECMWF show consensus for mild overnight conditions. Realistic challenges include an unexpected late-evening cold air advection or station-specific measurement anomaly, though diurnal heating and proximity to resolution make shifts improbable; final JMA daily summary expected soon.

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.
