Recent official forecasts for Wellington indicate a daytime maximum near 13–14°C under southerly winds and partly cloudy skies, moderating solar heating during early spring. These conditions align with climatological norms for September, where average highs hover around 12–14°C, and model consensus shows limited diurnal warming amid consistent airflow from cooler southern latitudes. Updated runs from regional agencies have stabilized expectations without major shifts from prior days, though minor variations in cloud cover or wind gusts could nudge the peak by 1°C. This scientific context underpins the market-implied odds clustering tightly on 13°C and 14°C as the most probable resolution thresholds.

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.
