Recent forecasts from NOAA and AccuWeather point to a high near 86–88°F in Miami on May 17, driven by a steady southeast flow of subtropical air under high pressure with partly cloudy skies and minimal afternoon convection. This setup aligns with May climatology—when average highs reach 84–85°F—but current model consensus shows slight warmth from lingering warmth after early-month heat, without a strong sea breeze or thunderstorm cooling expected until evening. Trader emphasis on the 86–87°F bin reflects the tight range in latest runs, with 88–89°F as the secondary outcome if mixing strengthens. Resolution will hinge on the official Miami International Airport reading, which typically peaks between 2–4 p.m. local time.
