MetService's latest forecast, issued early on April 16, projects Wellington's highest temperature on April 18 at 17°C amid gale-force northerlies and periods of rain with heavy falls, driving trader consensus toward 17–19°C outcomes with near-even implied probabilities around 27–30%. These closely matched odds reflect inherent short-range forecast uncertainty from a frontal system bringing warm northerly airflow—typically boosting highs above the April climatological average of 16–17°C—but capped by extensive cloud cover and precipitation, as seen in recent stormy conditions from Subtropical Storm Vaianu earlier this month. Model ensembles show slight divergence, with some runs edging toward 18–19°C if clearing occurs midday; watch for afternoon updates from MetService before resolution based on official airport observations.
