Current forecasts for Wellington on September 7 point to a daily high near 10°C, with 11°C a close second, as a low-pressure system drives persistent southerly to southeasterly winds of 20–30 knots, heavy rain, and thick cloud cover that limits solar heating. Official guidance from MetService and aligned models emphasize cool maritime air advection and minimal diurnal rise under overcast skies, keeping temperatures below seasonal averages. Recent model runs show little disagreement on these thresholds, with only modest warming possible if rain clears earlier than expected. Traders have priced the market accordingly, reflecting consensus around these values ahead of final observations.

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.
