Recent forecast model consensus from MetService and international numerical weather prediction runs points to a daytime high of 14–15°C for Wellington on May 18, driven by a stable southerly airflow and clear to partly cloudy skies over the Cook Strait. This setup aligns with typical May climatology, where mean daily maxima hover near 14–16°C under maritime influence that limits rapid warming despite light winds and good solar insolation. Recent observations from the prior week show similar settled conditions yielding peaks of 13–15°C, reinforcing trader positioning on these two outcomes. Minor model spread exists around cloud cover timing, but no significant front or northerly shift appears likely before resolution based on the latest guidance.
