This market will resolve to the temperature range that contains the highest temperature recorded at the Wellington Intl Airport Station in degrees Celsius on 18 Jun '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Wellington Intl Airport Station, available here: https://www.wunderground.com/history/daily/nz/wellington/NZWN. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve until the first data point for the following date has been published on the resolution source. 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.Recent forecast models from sources like MetService and international ensembles indicate a daily maximum near 12–13°C for Wellington on June 18, driven by typical mid-winter southerly flows and stable high-pressure influence keeping temperatures close to the June climatological average of 12–13°C. Trader consensus favoring 13–14°C (over 80% combined implied probability) reflects slight upward revisions in recent model runs accounting for possible northerly wind shifts or reduced cloud cover that could add 1°C, while lower outcomes remain discounted given limited cold-air advection signals. Seasonal outlooks from NIWA reinforce near-average conditions without strong anomalies, though short-term model spread on exact timing of any frontal passage introduces the modest tail risk priced into 15°C and above.
