MetService's latest forecast, issued late on April 11, projects a high of 20°C in Wellington on April 12 amid occasional rain turning persistent and heavy from midday before easing, accompanied by strong northeasterlies shifting to gale-force southerlies gusting to 90 km/h in exposed areas. This positions 19°C (38.5% implied probability) and 20°C (28.5%) as leading outcomes, reflecting trader consensus on cloud cover and precipitation capping peak afternoon heating despite initial northerly flow favoring above-average warmth—seasonal April highs average around 17°C per NIWA climatology. Heavy Rain and Strong Wind Watches signal potential upgrades, introducing uncertainty in exact peak timing; next model updates at 10am April 12 could refine trajectories as the frontal system approaches.
