**Forecast models from MetService, GFS, and ECMWF consensus point to a daytime maximum of 14–16 °C in Wellington on 19 September under northwesterly flow ahead of an approaching southwesterly change.** Spring conditions remain unsettled, with a recent cold front bringing rain and strong winds across New Zealand; northerlies have allowed mild air to reach the lower North Island while southwesterlies are expected to arrive later in the period. Historical September maxima average near 12–15 °C, so the current guidance sits slightly above normal. Traders assign the highest implied probability (63.5 %) to 16 °C because multiple model runs cluster there, with lower odds on 15 °C (19 %) and 17 °C (9.5 %) reflecting residual spread in wind timing and cloud cover that could trim or boost the peak by a degree. Updated official forecasts and any late model shifts before resolution will be the key near-term catalysts.

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.
