The heat is cranking up in Miami with a sizzling forecast that has both locals and tourists reaching for their water bottles and sunscreen. According to the National Weather Service, today Miami is spotted with just a few clouds and a balmy 78°F, as humidity clings at 69% creating a sticky atmospheric embrace that's all too familiar for this time of year.

It's not just the sunshine state's typical rays beaming down; an easterly wind is pushing through at 12 mph, offering only a slight relief from what is gearing up to be a steamy day with temps reaching the mid-80s, hot sunshine is expected to dominate on this Cinco de Mayo Sunday, and for those heading to the beach, keep an eye out for the high rip current risk, the wind is kicking up more than just sand, gusting as high as 20 mph at times, the chance of rain is slight enough that outdoor activities, including the Formula 1 event, should face no rainy interruptions, the NBC Miami reports.

Moving into the evening, Miami nights are expected to be partly cloudy with lows comfortable at around 75°F. The week ahead calls for a continuation of the heatwave, with a slight chance of morning showers giving way to a pattern of hot, humid afternoons and highs persistently sticking in the mid-80s.

As we march into the later part of the week, the thermostat is set to climb even further reaching the upper 80s, by late week South Florida might be hitting the season's first 90-degree afternoon, shaking up weather records with potentially the warmest mornings on record for the time of year, with overnight temperatures hovering around the balmy 75-degree mark, as locals and visitors alike might contend with this swelter that beckons for air-conditioned refuges and the cooling waves of South Florida's beaches.
