This market will resolve to the temperature range that contains the highest temperature recorded at the Wellington Intl Airport Station in degrees Celsius on 17 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Wellington Intl Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.MetService's latest forecast, updated April 16 afternoon, projects Wellington's highest temperature on April 17 at 18°C under fine skies and northwesterlies, anchoring trader sentiment with 40.5% implied odds for that outcome while 19°C trails closely at 34.0%. This tight race reflects model ensemble spread—NIWA indicating potential for 21°C amid warm air advection—versus baseline uncertainties from Wellington's variable microclimate, including gusty winds reducing insolation and sea breezes capping peaks. April climatology averages 16°C highs, but a stabilizing high-pressure ridge favors mild conditions; southerly shifts or added cloud could favor 17°C at 20.5%. Evening model runs and early April 17 observations will refine resolution based on Wellington Airport measurements.
