Current forecast models from sources including MetService and international ensembles point to a maximum temperature near 14°C in Wellington on August 28, driven by a trough approaching from the Tasman Sea that will deliver northerly flows advecting milder maritime air while a cold front introduces showers and gusty northwest winds up to 30 knots. This setup follows recent warmer anomalies, with daily maxima reaching 17°C on August 25 amid a brief high-pressure influence, but the approaching system introduces uncertainty in exact peak values through variable cloud cover, precipitation timing, and local orographic effects around the capital's hills and harbor. Ensemble spreads highlight how small shifts in front speed or wind direction could push the daily high across the 13–15°C range, consistent with climatological August averages of 13–15°C and the narrow historical variability at this coastal site. Traders appear to weigh these dynamic factors evenly across bins, reflecting the limited divergence among short-range guidance two days ahead.
