This market will resolve to the temperature range that contains the highest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 12 Apr '26. 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.Trader consensus on Polymarket heavily favors a Tokyo high of 21°C (40.5% implied probability) on April 12, closely trailed by 20°C (30%) and 22°C (25.5%), driven by the latest Japan Meteorological Agency (JMA) forecasts indicating mild daytime maxima under a persistent high-pressure ridge promoting clear skies and moderate solar heating. Recent observations confirm this positioning: Tokyo recorded unseasonably warm highs near 27–28°C on April 10–11 amid early-season heat warnings, but incoming cooler northerly flows and reduced insolation potential signal a dip to 20–22°C, aligning with JMA model ensembles showing tight spread around these values. April climatology averages ~19°C, underscoring the slightly above-normal outlook, though sea breezes or unexpected clouds introduce uncertainty; watch JMA's evening update for refined guidance ahead of resolution based on official Haneda Airport measurements.
