Highest temperature in Wellington on July 6?

Platform comparison

Market context

On 6 July 2026, the real-world event at hand is the highest temperature recorded at Wellington International Airport, measured in degrees Celsius and resolved via Weather Underground. In prediction markets, a YES share pays out if the temperature falls within the specified range, while a NO share pays out if it does not; here, the crowd currently assigns 0% probability to the YES outcome, implying strong confidence the temperature will exceed the lowest bracket.

Historical patterns and current forecasts frame this near-zero probability. July is Wellington’s coldest month, with average highs around 14°C (54°F), yet multiple numerical weather models and agency guidance issued within the past 48 hours cluster the likely maximum between 12°C and 13°C, creating a tight market split of 41.5% for 12°C and 33.5% for 13°C [1]. This aligns with NIWA’s seasonal outlook, which notes temperatures are equally likely to be near or below average in the South Island, with occasional cold snaps possible under persistent high pressure [3].

Traders should monitor short-term weather updates and atmospheric shifts, particularly southerly-quarter flow anomalies and rising high-pressure systems that may trigger fog or frost. The BBC’s 14-day forecast for Wellington International Airport currently predicts a high of 11°C with showers and a fresh breeze [4], while NIWA emphasises medium forecast confidence for temperatures and a drier lean that may intensify as the season progresses [3]. These dependencies will directly influence whether the day’s peak temperature lands in the lowest bracket or higher.
