This market will resolve to the temperature range that contains the highest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 29 Jun '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Tokyo Haneda Airport Station, 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 until the first data point for the following date has been published on the resolution source. 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. Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent Japan Meteorological Agency forecasts indicate mostly cloudy skies over Tokyo on June 29, with scattered showers possible earlier in the period, which limits daytime heating and supports maximum temperatures near seasonal norms of 25–27°C. Above-average temperature trends for the month, driven by broader atmospheric patterns and long-term warming, keep 26°C and 27°C as the closely matched market leaders, while reduced solar radiation from persistent cloud cover caps upside potential above 28°C. Official guidance shows minimal model divergence for this short-range period, with historical late-June baselines reinforcing the narrow 25–27°C range amid the ongoing rainy season. Traders are monitoring any last forecast updates on cloud breaks or frontal timing ahead of market resolution.
