MetService and NIWA forecasts, updated as of April 11 afternoon, project Wellington's highest temperature on April 12 at 19-20°C, driving trader consensus with 19°C at 41% implied probability, closely followed by 20°C (24%) and 18°C (22%). A low-pressure system will bring northerlies turning to strong easterly then southwesterly winds—potentially gales gusting 90 km/h—along with heavy rain (Heavy Rain Watch from 11am-11pm), capping daytime heating under increasing cloud cover. Today's observed max of 16.1°C at Wellington Airport aligns with this cooler autumn pattern, below the April average of 17°C, though dry breaks could nudge toward 20°C; monitor evening model updates for shifts ahead of resolution based on airport station data.
