Recent observations and forecast models from MetService indicate Wellington reached a daily maximum of 20°C on October 10 under northerly flow, partly cloudy skies, and springtime solar heating that supported above-average warming for the season. This aligns with historical October variability, where highs occasionally touch the low 20s when high pressure allows clear intervals despite typical coastal influences. Trader consensus at 100% for 20°C reflects convergence across official stations and real-time data, with skin-in-the-game incentives favoring precise measurement over broader ranges. Resolution hinges on the designated station's verified maximum; stronger southerly winds, increased cloud cover, or localized cooling could realistically keep the peak at 19°C or below if conditions shift before final recording.
