Trader consensus on Polymarket mirrors the narrow spread in official forecast models for Wellington, New Zealand, where MetService and ensemble guidance from ECMWF and GFS project a maximum temperature of 18–20°C on March 29, with 19°C edging ahead due to recent model runs favoring mild high-pressure influence over the region. Southerly winds and coastal cooling introduce uncertainty, potentially capping peaks at 18°C, while brief ridging could push toward 20–21°C; historical March averages hover at 20°C amid neutral ENSO conditions. Local topography amplifies variability through sea breezes and katabatic flows. Daily forecast updates from MetService, expected through late March, will refine these probabilities as resolution nears.

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.
