**Forecast models and real-time observations point to a nighttime low in the mid-20s Celsius as the dominant driver of trader positioning, with 26°C and 25°C holding the highest implied probabilities amid closely matched sentiment.** Persistent cloud cover, scattered thunderstorms, and elevated humidity from recent regional moisture patterns are limiting radiative cooling, keeping minimum temperatures above the long-term September 21 average of 23.7°C. Official guidance highlights light winds and dew points near 25–26°C, which support overnight stabilization around these levels rather than sharper drops. Historical analogs show occasional cooler outliers below 22°C under clearer, drier conditions, but current atmospheric setup favors the narrower 25–26°C range. Traders are monitoring updated model runs and local station readings through the night for any late shifts in precipitation or wind that could alter the final recorded minimum.

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=zggg
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.
