Trader consensus on Polymarket assigns a near-certain implied probability to a 19°C high temperature at Wellington International Airport on May 10, 2026, driven by real-time MetService observations showing peak readings of 19°C during midday under partly cloudy skies and lingering effects of strong northerlies that advected warmer air southward. MetService's latest afternoon forecast confirms this positioning with an 18–19°C range for the Wellington region, aligning with model consensus from short-range numerical weather prediction outputs that factored in post-shower clearing and reduced cloud cover. This exceeds May climatological averages of 15°C due to the frontal passage's warm sector. Scenarios challenging this include an improbable late-afternoon heat burst pushing to 20°C before evening southerlies and showers dominate, though official hourly data through 4 p.m. already locks in the maximum. Final airport readings expected by midnight.
