Highest temperature in Wellington on July 21?

Platform comparison

Market context

The market tracks the peak temperature recorded at Wellington International Airport on 21 July 2026, with settlement tied to Wunderground’s daily high for that specific station. Current crowd-implied probability sits at 0% for the YES outcome, yet Polymarket data shows the frontrunner outcome is 12°C at 100% probability, suggesting the market has effectively priced in a mid-range winter temperature rather than an extreme outlier [1]. This divergence between the binary YES probability and the specific temperature range implies traders view the event as a standard winter day, with 7°C or below holding negligible backing at 0% [1].

Historical winter patterns in Wellington typically see highs between 10°C and 15°C, aligning with the current 12°C consensus and the BBC’s recent observation of 15°C conditions at the same airport [2]. The 0% YES probability likely reflects a binary structure where the “YES” condition requires a temperature outside this normal band, making the current pricing a rational assessment of seasonal norms rather than an anomaly.

Traders should monitor the official Wunderground daily history release for NZWN on the settlement date, as this is the sole resolution source [1]. No external regulatory announcements or weather forecasts will alter the outcome, given the market’s reliance on post-event empirical data. For accessibility, the “no-KYC up to $1,500” threshold permits participation without identity verification, though German GlüStV and US CFTC frameworks may still impose jurisdictional limits on where such wagers are legally executable, regardless of the platform’s internal thresholds.

FAQ

Is Polymarket legal in my country?

Can I trade anonymously?

What if regulation changes?
