Recent MetService guidance and supporting ensemble model runs project a maximum of 14°C for Wellington on August 12 under fine but increasingly cloudy conditions with light winds, aligning closely with the city's climatological August average high near 12–14°C. NIWA's seasonal outlook reinforces near-average temperatures for the Wellington region through the winter period, with no strong warm or cold anomalies expected to shift the outcome. Trader consensus, reflected in the heavy weighting toward 14°C and 15°C outcomes, incorporates these official forecasts while accounting for typical model uncertainty ranges of 1–2°C and the potential for minor diurnal warming under variable cloud cover. Upcoming MetService updates and any revised model runs in the next 48 hours represent the primary near-term catalysts that could refine these implied probabilities.
