Official measurements from the National Weather Service confirm that Miami International Airport recorded a minimum temperature of 78°F early on June 16, 2026, placing it squarely in the 78-79°F bin now trading at full implied probability. This outcome aligns with typical early-summer climatology for the region, where overnight lows in mid-June commonly settle near 76-79°F under light winds and high humidity that limit radiational cooling. Forecasters noted stable atmospheric conditions with no significant cold-air advection or unusual cloud cover to drive temperatures lower. A data revision by the NWS or use of an alternate station reading could theoretically alter the official figure, though such changes are rare once preliminary climatological reports are issued.
