Recent forecasts from MetService and international models indicate a high of around 10°C for Wellington on August 18 amid persistent southerly flow and lingering effects from a recent polar air outbreak, positioning 9°C as the market leader. August climatology shows typical daily maxima near 12°C, but cooler-than-average conditions this month—driven by strengthened high-pressure systems and cold advection—have shifted trader consensus toward lower outcomes. NIWA’s seasonal outlook assigns the highest probability to near-average temperatures overall, yet short-term model runs highlight uncertainty in exact maximums due to variable cloud cover and wind strength. Updated guidance expected from national forecasters over the next 48 hours will likely refine these implied probabilities ahead of resolution.
