Trader consensus on Polymarket clusters tightly around 20–22°C for Wellington's highest temperature on March 27, driven by MetService's latest forecast pinpointing a 21°C peak amid northwesterly winds and partial sun, corroborated by ECMWF and GFS ensemble means hovering at 20.5–21.5°C. Differentiating these close outcomes are model divergences on wind persistence—sustained northwesterlies could advect warmer subtropical air to nudge toward 22°C, while early cloud-up or sea-breeze intensification might cap at 20°C—against Wellington's March historical average high of 20.3°C. Minimal odds beyond this range reflect low ensemble spread and no tropical influences, with official observations resolving via NIWA stations by midnight.
