Japan Meteorological Agency's latest short-term forecast pins Tokyo's lowest temperature on May 2 at 16°C amid sunny intervals and low precipitation risk (10-30%), promoting radiative cooling under light winds. Yet trader consensus clusters around 14°C (27%) and 15°C (23.5%), reflecting ensemble spreads from global models like ECMWF and GEFS, which show variability due to subtle differences in cloud cover persistence and upper-air patterns over the Kanto region. Early May climatology supports this range, with historical lows averaging 13-16°C influenced by urban heat island effects mitigating deeper cools. Key differentiators include overnight humidity and southerly flow strength; watch JMA's daily updates tomorrow for refined guidance as resolution nears.

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.
