Trader consensus favors a 21°C high in Wellington on March 28 at 34% implied probability, propelled by recent MetService and ECMWF ensemble forecasts centering maxima at 20-21°C amid a building high-pressure ridge fostering warm northerly flow. This narrowly outpaces 20°C (25%) and 19°C (24%), with differentiation hinging on wind shear and cloud forcing: persistent northerlies enable 1-2°C warm air advection above climatological norms (March average ~20.5°C at Wellington Airport), while encroaching southerlies or marine stratus could suppress peaks via boundary-layer cooling. Model spread reflects uncertainty in geopotential height anomalies, with 12Z updates likely to sway positions ahead of the event.

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.
