MetService's latest extended forecast, updated early April 2, projects Wellington's highest temperature on April 4 at 19°C amid mainly fine conditions, strengthening northerlies, and a chance of showers into evening, driving near-even trader consensus with 31.5% implied probability for 19°C and 30.5% for 20°C. This tight split stems from GFS and ECMWF ensemble spreads highlighting uncertainty in shower timing and cloud cover—light rain odds around 60% could suppress peaks, while afternoon clearing or warmer northerly bursts might push to 20-21°C. Slightly above early-April climatological averages of 17-18°C under neutral ENSO patterns, daily model updates and MetService revisions through April 3 will sharpen resolution odds based on Wellington International Airport observations.
