MetService's latest forecast, issued late April 4, projects a daytime high of 20–21°C at Wellington International Airport on April 7 under mostly cloudy conditions with a chance of afternoon showers and strong easterlies, driving trader consensus toward 21°C or higher (54.5% implied probability) and exactly 20°C (26.5%). This above-average outlook—historical April highs average 16–17°C—stems from a lingering high-pressure ridge delivering mild air amid ENSO-neutral conditions, as per NIWA's seasonal guidance. Cloud cover and onshore winds introduce uncertainty, potentially capping temperatures at 19–20°C if showers intensify, while clearer intervals could push beyond 21°C. Updated model runs expected April 6 may refine probabilities as resolution nears.
