Latest MetService, NIWA, and international model consensus project a daily maximum of 14°C at Wellington International Airport on August 12, 2026, under moderating northerly flow that tempers cool maritime air masses typical of August climatology (average highs near 12–13°C). Recent southerly episodes kept prior maxima at 10–12°C, but a developing high-pressure influence and reduced wind chill now favor modest warming while elevated cloud cover and gusts limit further rises. Trader consensus at 100% on 14°C reflects this narrow forecast spread; small shifts in frontal timing or wind direction could still produce a 13°C or 15°C outcome before official observations finalize resolution.
