Trader sentiment clusters tightly around 18-19°C for Wellington's March 25 high temperature, mirroring MetService's latest ensemble forecasts averaging 18-20°C under a stabilizing high-pressure ridge that curbs southerly gusts. Differentiating factors include model spread—ECMWF leans 19°C with clearer skies, while GFS variants hint at 18°C or 17°C if coastal sea breezes and partial cloud enhance cooling. March historical highs average 20°C, but lingering La Niña cool anomalies and urban heat island moderation in windy Wellington add downside risk, pricing 31.5% on 19°C versus 28% on 18°C. Watch evening model updates for frontal timing shifts.
