Wellington's mid-winter maritime climate typically produces daily maximum temperatures of 12–14°C in mid-August, shaped by prevailing westerly to southerly flows and frequent cloud cover that limit daytime heating. Current short-range model guidance from MetService and AccuWeather points to a maximum near 13–15°C for August 15, with light winds and possible morning showers keeping readings close to seasonal norms. NIWA’s June–August outlook assigns the highest probability to near-average temperatures across the Wellington region, consistent with the market’s leading 14°C outcome at 51.5% implied probability. Recent observations show highs fluctuating between 12°C and 15°C, and any late adjustment in steering flow or cloud timing could shift the exact peak by 1°C. Updated model runs and official briefings over the next 48 hours will provide the clearest signals for resolution.
