Wellington, New Zealand's capital city, experiences variable temperate weather patterns throughout the year. April sits in the autumn season, typically characterized by mild temperatures and increasing rainfall. This market predicts whether the highest temperature recorded in Wellington on April 20, 2026 will be exactly 13°C. At current odds of 5%, traders assess this outcome as highly unlikely, suggesting they expect temperatures to either exceed or fall short of this specific threshold. Temperature markets depend on official meteorological readings from sources like New Zealand's MetService, making them objectively resolvable. The specificity of this prediction—requiring the precise high temperature to match exactly 13°C rather than a range—explains the low probability assessment. Wellington's autumn weather often fluctuates between 10°C and 18°C depending on weather systems and seasonal patterns. The odds trajectory reflects incoming weather models and historical daily temperature variability. Traders can adjust positions until market close on April 20 at 00:00 UTC, after which official weather data determines the final outcome.
