Official meteorological observations from New Zealand's MetService confirm Wellington's maximum temperature reached 14°C on September 12, driving the market's near-certain consensus on that outcome. Springtime conditions featured typical westerly flows with moderate onshore influences moderating daytime highs, consistent with seasonal baselines around 13–15°C for the capital. Forecasters noted stable atmospheric patterns with limited cloud cover allowing brief warming but no significant advection of warmer air masses. This aligns with real-time station data and model consensus. Only an unprecedented late revision to official records or instrumentation anomaly could shift the result, though such events remain historically rare for verified daily maxima.
