Latest MetService ensemble forecasts peg Wellington's March 25 high at around 19°C, driving trader consensus with 27% implied odds on that outcome amid tight clustering for 18–21°C, reflecting model convergence from ECMWF (19.2°C) and GFS (19.8°C). Partly cloudy conditions and light northerlies favor mild warmth, but southerly sea breezes could cap peaks at 18°C, while brief晴 intervals might nudge toward 20°C, per historical late-March averages of 19.3°C and low-volatility coastal meteorology. Key differentiator: afternoon cloud development uncertainty, with hourly updates from NIWA monitoring stations likely to sharpen odds before resolution based on official airport observations.
