Highest temperature in Wellington on July 24?

Platform comparison

Market context

Polymarket is pricing the Wellington airport temperature contract at **0% YES** today, which means the market is assigning no probability to the day’s high landing in the contract’s specified range. The event is a single-day temperature print at Wellington International Airport, settled in **USDC** on **Polygon** through conditional tokens, with the outcome taken from Wunderground’s daily history page rather than from a subjective forecast.

The current setup fits Wellington’s July climatology more than a sharp warm-up story. Typical July highs are only around **12°C**, with average lows near **9°C**, and the month is usually wet and breezy, with more than **23 rainy days** and average wind speeds around **29 km/h**[1]. That makes materially warm outcomes uncommon, which helps explain why traders may be treating the upper temperature bands as remote.

For a Polymarket user, the main live inputs are the same-day weather evolution and any late shift in the airport reading before the settlement cutoff. AccuWeather’s hourly feed currently shows **49°F** at Wellington, with a **20%** precipitation chance and cloudy conditions, which is consistent with a cool start rather than an immediate spike[2]. The practical watchpoints are the airport’s actual midday heating, cloud break-up, and wind direction, since the market resolves on the highest observed temperature at the station, not a citywide average.
