Highest temperature in Wellington on July 28?

Platform comparison

Market context

Wellington's maximum temperature on 28 July 2026 will be recorded at the airport weather station and resolved against historical data from Wunderground. July falls within Wellington's winter season in the Southern Hemisphere, when daytime highs typically range between 8–13°C, though occasional warm fronts can push temperatures several degrees higher. The settlement window closes at midday UTC, requiring traders to commit capital before the full day's temperature range is known.

Historical July records for Wellington show considerable variability. The airport station has recorded July highs as low as 5°C during cold southerly outbreaks and as high as 18°C during unseasonably warm spells. The 0% crowd probability suggests traders are currently uncertain about which temperature bracket will resolve, or that liquidity constraints on deposit and withdrawal rails—particularly Klarna's payment processing and SEPA settlement timelines—are limiting participation. Traders depositing via Klarna should account for transaction processing times when positioning ahead of the settlement window.

Catalysts affecting the outcome include the Southern Oscillation Index and Tasman Sea surface temperatures, which influence whether anticyclonic or frontal systems dominate Wellington's weather on that date. The New Zealand MetService publishes extended forecasts approximately 10 days ahead, providing the clearest signal for traders to adjust positions. USDC withdrawal availability and SEPA settlement speed will determine how quickly traders can exit positions after resolution, affecting book depth and the willingness to commit larger stakes to temperature brackets with tighter odds.
