Pronóstico: Highest temperature in Wellington on July 7?

Platform comparison

Market context

The underlying real-world event is the highest temperature recorded at Wellington International Airport on 7 July 2026, measured in degrees Celsius. Current crowd-implied probability sits at 0% for the YES outcome, reflecting the market’s view that the temperature will not fall within the specific range being traded. On Polymarket, this contract is priced using conditional tokens on the Polygon network, with USDC as the settlement currency, and the current pricing suggests traders are betting against the temperature hitting the target threshold.

Historically, July is Wellington’s coldest month, with average minimums near 9°C and daily highs typically around 13–14°C (53°F), rarely exceeding 14°C [7][9]. The all-time maximum for Wellington (Kelburn) reached 30.3°C during a recent heatwave, but such extremes are exceptional and not typical for midwinter [4]. Given this pattern, the 0% probability aligns with long-term climate data showing that temperatures in early July seldom breach higher thresholds, making the current market reading consistent with comparable historical cases.

Traders should monitor upcoming weather forecasts from NIWA and local meteorological services for any anomalies, such as unseasonal heatwaves or cold snaps, which could shift probabilities [4]. While no specific announcements are scheduled for 7 July, dependencies include real-time data from Wunderground, which will serve as the official resolution source. A sudden spike in temperature—though unlikely—would be the primary catalyst to watch, but current seasonal trends suggest stability around the 13–14°C range.
