Highest temperature in Wellington on August 3?

Platform comparison

Market context

Wellington’s **3 August 2026** high will be the figure that matters here: the market resolves to the temperature band containing the day’s maximum at Wellington Intl Airport Station, as reported by Wunderground. August is normally a cool month in Wellington, with average highs around **12–13.6°C** and monthly lows near **4–9°C**, so the current **0% YES** crowd view implies traders are pricing in a reading that lands outside the market’s chosen band or a day that fails to reach a comparatively warm outcome.[1][3][8][13]

Historically, Wellington’s August weather is fairly compressed, which matters for reading this contract. Comparable climate datasets put typical August highs in the low teens Celsius, but the city has still produced materially warmer spikes, with one August record cited at **61°F / 16.1°C** in recent historical summaries, showing that tail outcomes are possible even in winter.[7][13] On platforms such as Polymarket, the price is usually shown as an implied probability; on Kalshi and Betfair, traders more often see contract prices or decimal odds, so a small move in the book can look different even when the same weather expectation is being expressed. Fee treatment also differs: exchange-style venues typically net fees or commissions differently, and access can vary by jurisdiction and KYC rules, which affects who can trade this kind of local weather event.

For catalysts, the key variables are the day’s actual airport observations, the timing of the warmest part of the afternoon, and any synoptic shift from fronts or southerlies that caps the maximum temperature early. Wellington can be highly changeable, and airport readings may differ from city-centre feel because of wind and coastal exposure; that makes the Wunderground airport feed the operative source, not broader Wellington forecasts. At 05:27 UTC on settlement day, traders should watch forecast updates, the hourly airport trend, and any change in cloud, wind or precipitation that could pin the day’s high below the expected band.
