Northwesterly winds are the main driver positioning 17–18°C as the leading outcomes for Wellington’s maximum temperature on September 4, transporting milder air masses northward ahead of a front and producing above-average spring values. Multiple guidance sources, including Met Office and regional models, converge on daytime peaks of 16–18°C (roughly 61–64°F) amid partly cloudy skies, scattered showers, and gusty conditions, with historical early-September averages near 13–14°C providing climatological context. Strong wind warnings and model consensus on limited solar heating from cloud cover support the market’s heavy weighting toward these levels, though any late-day clearing or wind shift could alter the exact peak before resolution.

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.
