The National Weather Service's latest forecast for Miami projects a high temperature near 83°F on March 27 under clear skies and light winds, anchoring trader consensus on the 82-83°F outcome at 38.5% implied probability, narrowly ahead of 80-81°F at 32.5% amid model ensemble variations. Recent GFS and ECMWF runs average 82°F, boosted by post-cold-frontal warming, dry mid-level air aloft, and subdued sea breeze effects that allow afternoon peaks before evening cooling. March climatology at Miami International Airport typically sees highs around 79°F, but this week's above-normal trend has elevated expectations. Key differentiators include precise sea breeze timing and urban heat island influences, with new soundings and 12z model updates expected to narrow the 2°F spread driving tight odds.
