Trader consensus on Polymarket tilts toward a 19°C high in Wellington on March 26 at 33.5%, narrowly ahead of 20°C or higher (28%) and 18°C (23%), reflecting ensemble forecasts from ECMWF and GFS models clustering tightly around 19°C amid a high-pressure ridge ushering northerly winds. Differentiation hinges on wind strength and timing: sustained northwesterlies above 20 knots could push advection of subtropical air to 20°C+, but prevailing sea breezes and afternoon cloud buildup—common in Wellington's coastal microclimate—favor moderation to 18-19°C per MetService guidance. Historical March maxima average 20°C, but model spread underscores 1-2°C uncertainty from evolving synoptic patterns.
