Recent forecast consensus from MetService and global models positions a 13–15°C high for Wellington on August 24 as the most likely outcome, driven by a northwest flow advecting milder maritime air after earlier fronts clear. Northwesterly winds of 15–30 km/h under mostly sunny or clear skies support modest diurnal warming above seasonal averages near 12°C, while stable high pressure limits cloud cover and precipitation that could suppress maxima. Trader emphasis on 15°C reflects model agreement on peak readings in this range, with limited upside to 16°C or higher unless winds strengthen further. Final model updates and observational trends through August 23 will refine these probabilities ahead of resolution.
