Recent Japan Meteorological Agency forecasts for Tokyo on August 24 project a minimum of 25°C under partly cloudy skies with highs near 34°C, aligning closely with climatological norms of 24–25°C driven by the persistent subtropical high, elevated humidity above 70%, and Tokyo’s urban heat island effect that restricts nocturnal radiative cooling. Ensemble model guidance shows minor divergence on overnight cloud cover and wind patterns, which can shift the low by 1°C and explain the tight market split favoring 25°C at 52.5% implied probability over 26°C at 43.5%. Traders weigh these variables against historical late-August observations where minima cluster tightly around seasonal baselines, with limited downside risk for 24°C or below given current atmospheric conditions. Updated JMA briefings and NOAA observational data ahead of resolution will refine this assessment.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rjtt
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
