Trader consensus on Polymarket heavily favors 78-81°F highs at Miami International Airport today, with 78-79°F and 80-81°F each implying near-40% probabilities, reflecting tight clustering in National Weather Service guidance and ensemble model outputs from GFS and ECMWF around 79-80°F. Persistent moderate easterly winds—15-20 mph from the Atlantic—promote onshore flow that moderates daytime heating despite mostly sunny skies and highs starting from overnight lows near 71°F, keeping temperatures slightly below the April 1 climatological normal of 83°F. Scientific uncertainty stems from variable sea breeze timing and potential afternoon cumulus clouds, which could cap peaks at 78°F or allow slight inland warming to 81°F; real-time observations and late-day updates will sharpen resolution as the market nears close.
