Trader consensus on Polymarket assigns a 100% implied probability to a highest temperature of 16°C at Wellington International Airport station on April 19, driven by official MetService observational data confirming this peak amid cloudy conditions, heavy showers, and a wind shift from northerlies to cooler southerlies. Initial forecasts from late April 17 projected up to 17°C, but persistent precipitation and cloud cover—evident in real-time radar and current readings around 13–16°C—have capped warming, aligning with April climatological norms of 16–18°C daily highs. Model consensus from MetService supports no further intensification, with unsettled weather prevailing. A realistic challenge would require unexpected clearing and sustained northerlies before sunset, though current atmospheric conditions make this improbable; final daily observations will confirm resolution.
