Miami residents can expect to bask in sunny skies and experience heat well into the 90s well into the coming week. Forecasts from the National Weather Service predict high temperatures near or above the 90-degree mark with sustained sunny conditions due to a strong ridge of high pressure in the upper atmosphere.

Starting the day off with temperatures in the mid and upper 70s, Miami is in for another "hot and humid day," according to NBC Miami. Today’s high is anticipated to hover around 90 degrees, with southeastern winds gently picking up to a slight 5 mph in the afternoon. The weekend shows a similar pattern, with highs inching towards 91 degrees on Sunday and humidity, are set to make it feel even warmer.

A persistent high-pressure system over South Florida is doing more than just bringing sunshine and heat—it's acting as a protective shield, keeping storm systems impacting other parts of the country at bay. As a result, the forecast remains dry through the weekend and into early next week, with no rain in sight. This stretch of calm weather offers clear skies for now, even as the region quietly approaches the start of hurricane season, now less than two weeks away.

Adding to the clarity of the sun-soaked days, NBC Miami anticipates no significant changes until late next week, remarking, "Next best chance for rain isn’t until the end of next week, and even then it’s a low chance."

Overnight temperatures in South Florida are expected to stay warm, only dropping to the high 70s. While light southeastern winds may provide a slight breeze, the high humidity will push the heat index even higher, potentially reaching the mid-90s, making it feel even hotter than the actual temperature.
