Trader consensus on 27°C as the highest temperature in Busan on September 10 reflects real-time observational data and model outputs showing a daytime peak near that level under partly cloudy skies with moderate northeasterly flow. Korea Meteorological Administration stations and ensemble forecasts indicate afternoon readings stabilizing around 26–28°C, consistent with seasonal norms for early September in the region where solar heating and sea-breeze moderation typically cap extremes. Minor probabilities for 28°C or higher account for possible localized urban heat effects or brief model run variations, while lower outcomes remain improbable absent rapid cooling from unexpected cloud build-up or wind shifts. Final resolution hinges on official daily maximum verification, with any measurement revisions capable of altering edge cases near the threshold.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=rkpk
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
