Miami is waking Friday under clear skies and temperatures around 82 degrees, but the calm start will give way to a hot, breezy afternoon. The high is expected to reach 89 degrees, with the heat index climbing as high as 105. The heat may make outdoor plans more challenging as the day wears on.

Southeast winds will run 13 to 16 mph, with gusts up to 20 mph.

High Tides Bring A Coastal Flooding Concern

A Coastal Flood Statement remains in effect for coastal Miami-Dade County through Saturday morning, with isolated minor flooding possible during high tide. Drivers should not attempt to cross flooded roadways, according to the National Weather Service Miami-South Florida office.

The coastal flooding risk is tied to unusually high tides, while southeast winds may push additional water toward the shoreline. Residents in flood-prone coastal areas should keep an eye on rising water around the high-tide cycle and avoid leaving vehicles in spots that routinely flood.

Beach And Boating Conditions Turn Rougher

Beachgoers should also be cautious as onshore winds strengthen. The forecast calls for a moderate rip-current risk along Atlantic beaches in Miami-Dade and Broward counties, while the Palm Beaches face a high risk. Swimmers should stay near lifeguards and avoid entering the water when flags or local officials indicate dangerous conditions.

Swells are spreading toward the Gulf Coast. The boating forecast calls for seas of 3 to 4 feet, occasionally 5 feet.

Weekend Heat Holds

Saturday looks much like Friday, with a high near 89, heat index values up to 105 and a 40% chance of showers and thunderstorms. South winds should be around 14 mph, with gusts to 22 mph. Sunday should be mostly sunny after a small early shower chance, but temperatures will still rise to about 89 degrees.

Monday remains warm, with a high near 89 and only a slight chance of afternoon storms. Storms are expected to arrive Tuesday and Wednesday.
