Highest temperature in Wellington on August 6?

Platform comparison

Market context

Polymarket is pricing this Wellington airport temperature range contract at **0% YES**, which means the market is effectively saying no USDC is currently assigned to the outcome that the day’s high will fall in the specified band. On Polymarket, that price reflects trading in conditional tokens on Polygon rather than a view on the weather itself, so the key issue is whether the highest reading at Wellington Intl Airport on the settlement day lands in the exact range used by the market’s resolution rules.

August in Wellington is typically cool, with recent weather guides putting average highs around 11–12°C and lows around 8–9°C, while airport observations commonly sit in single digits to low teens and can be influenced by wind and passing rain bands.[2][4][7] That seasonal backdrop makes a very warm maximum less common, which helps explain why a contract tied to a particular high-temperature band can trade near zero when the market thinks the day will stay close to normal winter levels rather than spike upwards.

For traders, the main catalysts are the intraday forecast updates, the exact airport observation reported by Wunderground, and any short-lived weather changes from northerly winds, showers or clearing skies that can lift the daytime peak by a degree or two.[7][11][16][17] In practical terms, this is a narrow-data market: the settlement depends on the highest temperature recorded at Wellington Intl Airport Station by the cut-off, so Polymarket holders are watching for the airport’s hourly evolution more than the city-wide forecast headline.
