Trader consensus on Polymarket has locked in 86-87°F at 100% implied probability for Miami's highest temperature on April 30, 2026, driven by official National Weather Service observations at Miami International Airport (KMIA), the market's resolution station. Hourly data confirmed a peak of 87.1°F around 1 p.m. EDT amid partly cloudy skies, sea-breeze moderation, and typical late-April climatology with average highs near 85°F. This aligns with NOAA's preliminary climate summary, showing no extremes like heat advisories. Realistic challenges are minimal post-event—only a rare data audit or sensor recalibration by NWS could revise the record, but finalized reports rarely shift by more than 0.1°F. Traders await no further updates as the market nears resolution.
