Trader consensus overwhelmingly favors 13°C as Tokyo's highest temperature on March 17, driven by the latest Japan Meteorological Agency (JMA) forecasts projecting a daytime high of exactly 13°C under partly cloudy conditions with light northerly winds and no significant warm air advection. This aligns with seasonal norms—Tokyo's March averages hover around 12-14°C—and recent cool fronts suppressing temperatures, as confirmed by surface observations and ensemble model outputs from ECMWF and GFS showing low variance around this value. Realistic challenges include an unforeseen shift in upper-level ridge patterns causing adiabatic warming or urban heat island amplification pushing toward 14-15°C, though such deviations occur in under 10% of similar setups historically.

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 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.
