The National Weather Service's official climatological summary for April 9, 2026, confirms a maximum temperature of 79°F at Miami International Airport (KMIA), measured by the automated surface observing system (ASOS) amid a stalled frontal boundary over South Florida. Persistent stratus cloud cover, fog, light rain totaling 0.67 inches, and gusty onshore winds sharply curtailed solar insolation, preventing the typical convective heating seen in early April—yielding a high 4°F below the 83°F climatological normal. Trader consensus at 100% on 78-79°F reflects this verified observation, with negligible odds elsewhere. Realistic challenges would require rare NOAA data revisions from quality control audits, though historical precedents show such adjustments occur in under 1% of daily records.
