**Southerly winds following a frontal passage are the main driver capping Wellington's maximum temperature on September 23 around 10–11 °C.** Multiple model runs and official guidance show a cool maritime airmass advecting northward, with daytime highs forecast near 50 °F (10 °C) under partly cloudy skies and a 50–60 % rain chance. This aligns with the market-implied odds favoring 11 °C (56 %) over 12 °C (34.5 %), reflecting tight clustering of ensemble outputs around the seasonal average adjusted for the post-frontal regime. Historical September maxima average 13–14 °C, but the current steering pattern and dew-point suppression limit upside risk, keeping lower outcomes (≤10 °C) at modest probability while still allowing minor model spread for 12 °C. Updated NWP runs and local observations over the next 24–48 hours will refine the exact peak.

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=nzwn
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.
