Cloud cover and breezy northerly winds are suppressing daytime solar heating across the Tokyo region on June 5, positioning the daily maximum near 20–21 °C according to current observational data and short-range models. Early June climatology typically features highs of 25–26 °C under clearer skies, yet persistent overcast conditions and moderate humidity are limiting radiative warming and keeping surface temperatures several degrees below average. Official forecasts from monitoring agencies highlight these factors as the dominant controls on peak readings, with minimal expected variability from localized heating or sea-breeze effects. As the day concludes, final station measurements will determine resolution, though the present atmospheric setup strongly favors outcomes clustered around the lower end of the seasonal range.

This market will resolve to the temperature range that contains the highest temperature recorded at the Tokyo Haneda Airport Station in degrees Celsius on 5 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.Cloud cover and breezy northerly winds are suppressing daytime solar heating across the Tokyo region on June 5, positioning the daily maximum near 20–21 °C according to current observational data and short-range models.
