Official observations from Wellington International Airport, New Zealand's primary weather station for this market, confirm a peak temperature of 16°C on May 12, 2026, as recorded in MetService hourly data around midday under partly cloudy conditions and moderate southerly winds—driving trader consensus to a 100% implied probability for this outcome. This aligns precisely with short-range forecast models from MetService and ensemble projections showing minimal spread, consistent with May climatological norms of 14.5–15°C averages from NIWA records amid cool autumn air masses from the south. Realistic challenges are negligible post-validation, limited to rare data revisions in the Wunderground history used for resolution or unverified instrument anomalies, though southerly persistence and cloud cover precluded higher readings.
