Forecast models from MetService and international agencies converge on a daily maximum of 18°C for Wellington on June 5, driven by a northwesterly flow bringing mild air under partly cloudy skies with light showers possible. This aligns with early-winter climatology for the region, where average highs hover near 14–16°C but recent warm anomalies earlier in the month have kept temperatures elevated. Official resolution relies on the highest reading at Wellington International Airport, and current guidance shows little deviation expected before the close of the observational period. A shift in wind direction toward stronger southerlies or increased cloud cover could cap the peak below this level, while clearer conditions or stronger northerlies might allow a brief spike to 19°C.
