Trader consensus on Polymarket has locked in a 100% implied probability for a highest temperature of 15°C at Wellington International Airport on April 30, 2026, backed by official MetService observations and Weather Underground archives confirming the daily maximum peaked at exactly 15°C. This aligns precisely with MetService's pre-dawn forecast projecting a 15°C high amid a cool southerly airflow replacing yesterday's warmer northwesterlies, which had pushed temperatures to 17°C; mainly fine skies and a chilly 6°C overnight low further capped daytime warming potential. April climatology typically sees Wellington highs near 17°C, but today's stable high-pressure ridge and light winds limited solar heating. Scenarios challenging this would require a rare post-finalization data revision uncovering an overlooked peak, though MetService verification processes make this improbable as the day concludes.
