Recent forecasts from multiple models indicate clearing skies and a warming trend in Busan after rain and cooler conditions on September 18, positioning 28–29°C as the most probable maximum on the 20th under trader consensus. Seasonal norms for late September feature daytime highs near 25–27°C, with the current setup reflecting a shift toward higher pressure and reduced cloud cover that favors greater solar heating during peak afternoon hours. Official Korean Meteorological Administration guidance and ensemble runs show minimal precipitation risk and light northeasterly winds on the 20th, limiting cooling effects while supporting modest daytime rises above recent baselines. Model agreement remains strong on these thresholds, though minor revisions in timing or marine influence could adjust the exact peak. Updated guidance ahead of the date will provide the next key data point for resolution criteria.

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.
