MetService's latest forecast, issued April 15, pegs Wellington's high temperature at 18°C on April 17 under initially fine skies with morning showers and northwesterlies strengthening to gale force, driving trader consensus toward 18°C (34% implied probability) over 19°C (31%). This closely matched positioning reflects model ensemble spreads in the 17–19°C range, where warm northwesterly advection from the Tasman Sea could elevate peaks if clouds dissipate quickly, while persistent showers and strong winds might suppress them toward 17°C (22%). Short-range uncertainty persists due to evolving frontal dynamics; updated National Weather Service guidance expected April 16 morning could shift odds further as observations refine the outlook. Historical April highs average 17°C, contextualizing the tight race.
