Japan Meteorological Agency forecasts position Tokyo’s May 17 maximum near 28–29 °C at the Otemachi station, driven by a high-pressure ridge fostering southerly warm advection and strong afternoon insolation. This synoptic pattern favors peak readings in the upper 20s to low 30s, keeping the 29 °C and 30 °C-or-higher outcomes nearly even in trader pricing while 28 °C remains close behind. Ensemble model consensus shows modest spread in boundary-layer heating and wind speeds, creating the tight probability clustering; any late-day cloud increase or slight steering shift could cap the high at 28 °C, whereas sustained clear skies would push it to 30 °C or above. The next JMA update and afternoon satellite trends will refine these thresholds before resolution.

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.
