Highest temperature in Wellington on July 24?

Platform comparison

Market context

Polymarket is pricing the Wellington airport high temperature contract with **14°C** as the clear front-runner at 63¢, while **13°C** sits at 22¢ and the rest of the curve is thinner. In Polymarket terms, that means traders holding the correct Celsius band would receive **USDC** on **Polygon** if the conditional token resolves in their favour, with settlement tied to the recorded daily maximum at Wellington Intl Airport Station rather than a generic city forecast.[1]

That pricing fits Wellington’s July climatology, where mid-winter highs are usually in the low teens rather than the mid-teens, and July is also a wet month with frequent rain and cloud cover that can cap daytime warming. For a market already implied at 0% YES for an unspecified side, the practical read is that the contract is being treated as a narrow temperature-range trade: small shifts of 1°C matter, but the distribution is still clustered around the 13–14°C bins rather than any warmer outcome.[2][1]

The main catalysts are the same factors that move any airport-temperature market: overnight cloud, wind strength, and the timing of the day’s warmest hour. Traders will usually watch local forecast updates, especially any late change in sun break timing or southerly flow, because those can push the eventual maximum up or down by a single degree and flip the winning band. Resolution will ultimately depend on the daily high reported by Wunderground for Wellington Intl Airport Station, so the only on-chain reality that matters at expiry is which conditional token maps to that exact recorded maximum.[1]
