Trader consensus overwhelmingly favors a Tokyo high of 13°C on March 25, driven by Japan Meteorological Agency forecasts projecting exactly that amid persistent cool northerly winds following a recent cold front. Ensemble models from ECMWF and GFS align closely, showing low-level stability and cloud cover capping daytime heating, consistent with late-March climatology where historical maxima average 12-14°C. Urban heat island effects provide minimal uplift in these conditions. Realistic challenges include an unforeseen ridge of high pressure introducing southerly flow or adiabatic warming from foehn-like downslope winds off the mountains, though current upper-air patterns make such shifts improbable before 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 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.
