**Trader sentiment locks in 19°C** as Wellington, New Zealand's highest temperature on March 23, propelled by MetService's official forecast capping the max at 19°C amid partly cloudy conditions and light southerly winds. Supporting evidence from ECMWF and GFS ensemble models shows tight clustering around this value, with minimal spread due to a dominant high-pressure ridge stabilizing the region—historical late-March averages sit at 20°C, but cool air masses have shaved 1–2°C off recent days. Upside risks like a sudden northerly airflow or enhanced insolation from clearer skies could push toward 20–21°C, though model probabilities price this below 1%, reflecting low forecast uncertainty.
