Forecasts for Wellington on August 28 indicate a high near 13–14°C under partly cloudy skies with showers and strong northerly winds, aligning with recent observed maxima of 14–15°C amid a broad trough moving eastward across the Tasman Sea. Northerly flow typically advects milder air masses from subtropical regions, elevating daytime peaks above the late-August climatological average of roughly 12°C, while variable cloud cover and precipitation introduce uncertainty in surface heating and boundary-layer mixing. Model consensus from agencies like MetService and ECMWF supports this range but can shift with updated runs on wind strength or frontal timing, factors that directly influence peak temperature resolution criteria for the market. Trader sentiment remains balanced across bins due to these narrow margins and inherent forecast variability near the 48-hour horizon.
