Official MetService observations from Wellington International Airport—the market's resolution station—confirm the highest temperature on April 11 reached 20°C mid-afternoon, amid a mild autumn day with increasing high cloud cover and light northerlies limiting further warming. This aligns with seasonal climatology, where Wellington's April average highs hover around 18°C, and model consensus had projected 19–21°C before observations locked in the peak. Trader sentiment reflects near-certainty at 100% implied probability for 20°C, backed by real-time data showing subsequent cooling into the evening. Realistic challenges would require a rare data revision uncovering a higher unlogged peak, though station reliability and the day's progression make this improbable. Final MetService summaries expected shortly.
