Highest temperature in Wellington on July 14?

Platform comparison

Market context

On 14 July 2026, Wellington International Airport will record a daily maximum temperature, and this market settles based on which range that figure falls within. The current 0% YES probability reflects the market's assessment of a specific temperature band—likely an extreme upper threshold—rather than scepticism about whether a reading will occur at all. Polymarket's conditional token structure on Polygon means traders are staking USDC against discrete outcomes; the crowd has priced one particular bracket as effectively impossible.

Wellington's winter climate in mid-July typically produces daily highs between 10–13°C, with extremes rarely exceeding 15°C. Historical records show that temperatures above 18°C on this date are exceptionally rare; the airport station has recorded only isolated instances of such warmth during July's coldest month. The 0% pricing suggests the market is testing an upper-range bracket—possibly 20°C or higher—which would require either an unusual warm front or a data anomaly to materialise.

Traders monitoring this contract should track MetService forecasts released in early July 2026, which will clarify whether any unusual pressure systems or warm air masses are expected to affect the region. Southern Hemisphere winter patterns, including the position of the polar vortex and any blocking highs over the Tasman, will determine whether conditions deviate from Wellington's typical July baseline. Settlement depends entirely on the Wunderground historical record for NZWN station, making data availability and sensor calibration the final arbiter once the day concludes.
