Latest MetService forecasts indicate a high of 21°C for Wellington on March 28, aligning with trader consensus at 40% implied probability, as a lingering cool southerly airflow suppresses temperatures amid partly cloudy skies and moderate winds. Ensemble model runs from global systems like ECMWF and GFS show tight clustering around 20–22°C, reflecting stable upper-air patterns and sea surface temperatures near seasonal norms of 18–19°C offshore. Recent observations—yesterday's high of 19°C and minimal overnight warming—bolster the 20°C (23%) and 21°C leads, while low odds on 23°C or higher (6.6%) account for limited solar insolation potential. Updated hourly data from Wellington's monitoring stations expected throughout the day could refine these market-implied odds.
