Official observations from the National Weather Service recorded a daily maximum temperature of 90–91°F at Miami International Airport on August 4, underpinning the market’s full consensus on that narrow range. Subtropical summer conditions, including typical Gulf Stream moderation and afternoon sea-breeze effects, produced standard late-summer readings consistent with long-term August climatology near 90°F. Forecast models had converged on this outcome days earlier, and no heat-wave or anomalous high-pressure setup altered the pattern. While final quality-controlled data releases could theoretically shift a preliminary value by a degree, such revisions remain rare for primary airport stations.
