Recent forecasts from MetService and global models indicate mostly clear skies and light northerly winds for Wellington on September 24, favoring moderate overnight radiative cooling after daytime highs near 12–13°C. Southerly flow earlier in the week has kept conditions near seasonal norms, but the building high-pressure ridge limits cold-air advection while preventing calm conditions needed for sharper drops below 5°C. Marine influence and variable cloud cover introduce uncertainty in minimum readings, with some ensemble members supporting lows near 7°C and others cooler if winds ease further. Trader consensus reflects this narrow range of outcomes, balancing historical spring variability against current model consensus. Updated guidance from the New Zealand MetService remains the key near-term catalyst.

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=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.
