MetService's latest forecast holds the highest temperature in Wellington at 19°C on April 13, driving trader consensus with 34% implied probability, as a post-frontal pattern features strong westerlies easing to northerlies, promoting mild above-average conditions typical for autumn. Closely trailing outcomes at 18°C (29%) and 20°C (26%) reflect model ensemble uncertainty around shower timing and cloud cover, which could reduce insolation and cap peaks, or allow northerly flow to boost highs amid clearing skies. Historical April highs average 16°C, but current wind regime favors the 18–20°C cluster; watch for Sunday evening updates from NZ's national forecaster as resolution nears.
