Highest temperature in Wellington on July 1?

Platform comparison

Market context

The underlying real-world event is straightforward: what will be the highest temperature recorded at Wellington International Airport on 1 July 2026, measured in degrees Celsius. Today, Polymarket prices the YES outcome for any temperature range above freezing at 0%, reflecting the market’s certainty that July in Wellington is cold. This aligns with historical data showing July is the coldest month in Wellington, with average highs of only 53°F (11.7°C) and average lows of 45°F (7.2°C)[4]. The all-time maximum for Wellington (Kelburn) reached 30.3°C, but this occurred on a different date and under exceptional heatwave conditions, not in early July[1]. Even New Zealand’s national record of 42.4°C was set in Lincoln, Canterbury, far from Wellington’s coastal climate[6].

Traders should monitor the National Institute of Water and Atmospheric Research (NIWA) for any unusual heatwave announcements or southerly wind shifts that could temporarily elevate temperatures, though such events are rare in July[1]. The settlement depends entirely on Wunderground’s daily high for Wellington Intl Airport, and no other station data will resolve the market. While Wellington’s historic hottest day hit 34.2°C in 2013, that occurred in mid-July, not early July[7]. Given the on-chain mechanics using USDC on Polygon and conditional tokens, the 0% price suggests no credible catalyst exists to push temperatures above freezing on this specific date. The market’s resolution window ends 2026-07-01T12:00:00Z, leaving little time for late-weather surprises.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
