Recent forecasts from MetService, NIWA, and international models indicate mild conditions for Wellington on August 27, driven by persistent northwesterlies that limit radiative cooling and suppress cold air advection from the south. Overnight lows are projected in the 9–12 °C range, consistent with near- or slightly above-average temperatures for late winter, when the climatological mean minimum sits near 8 °C. The absence of strong southerly changes or clear-sky radiative nights in the latest model runs supports the market’s clustering around 8–10 °C as the most probable outcomes, while the modest probabilities for 7 °C or lower reflect the limited window for any late intensification of cooling. Updated guidance through the next 48 hours will refine these probabilities as the event window approaches.
