Recent MetService forecasts and model guidance indicate a shift toward cooler southerly airflow over Wellington by August 16, supporting the market’s strong consensus around a 10°C daily maximum. This reflects typical mid-August variability, where the city’s long-term average high sits near 12°C but daily outcomes often range 9–14°C depending on wind direction and cloud cover. Recent days have seen warmer readings of 13–14°C under lighter northerly influences, yet the developing southerlies are expected to cap temperatures, aligning with the 64% implied probability for 10°C and secondary support for 9–11°C outcomes. Updated official guidance ahead of the weekend will likely refine these probabilities further.
