Miami, FL – As South Florida faces a scorching heat advisory with feels-like temperatures soaring to 108 degrees, residents are preparing for a Labor Day weekend unlike any other. While other regions of the country begin to cool off, Miami’s weather is set to remain hot and humid, with daily highs in the low 90s accompanied by significant chances of rain and thunderstorms throughout the holiday.
From Wednesday through Labor Day Monday, Miami-Dade and Broward counties can expect a mix of steamy temperatures and pervasive wet weather, prompting locals and visitors alike to reconsider their outdoor plans. Here’s what you need to know to stay safe and comfortable this long weekend.
Expect Both Heat and Rain: What Miami’s Weather Has in Store
Meteorologist Chuck Caracozza of the National Weather Service in Miami explains that a stalled weather boundary just north of the area will pull additional moisture into South Florida, elevating the chances of afternoon and evening rain showers and thunderstorms along the East Coast metro areas, including Miami and Fort Lauderdale.
“That is going to shift the showers and thunderstorms pretty much towards the east coast metro areas,” said Caracozza.
Despite the wet weather, the National Hurricane Center confirmed on Tuesday that there are no new tropical disturbances expected in the coming week, meaning that the rain is stemming from local atmospheric conditions rather than tropical storms.
Rain Chances Throughout Labor Day Weekend
Here’s a detailed forecast of rain probabilities during the upcoming days in Miami-Dade and Broward counties:
- Thursday: 50% chance during the day, 40% at night
- Friday: 40% to 70% chance – the start of the long weekend and a key travel day
- Saturday: 70% chance
- Sunday: 70% chance
- Labor Day Monday: 70% chance reducing to 50% by nighttime
- Tuesday: 70% chance of rain and thunderstorms as many return to work and school
Caracozza suggests that this soggy weather pattern may start to ease up after Tuesday but emphasizes that it’s still too early to predict exact conditions for next Wednesday.
Key West Labor Day Forecast: Slightly Drier Skies for the Festivities
For those heading to Key West’s “Just a Few Friends: Key West Favorite Son Celebration”—a nod to the late Jimmy Buffett with parades, concerts, and book signings—rain chances remain consistently at 40% from Friday through Tuesday. While not entirely rain-free, the Keys will likely see less rainfall than Miami’s metro areas, with no weather advisories as of Wednesday ahead of the festivities.
Will the Rain Bring Relief from the Heat?
Despite the increased rain chances, South Florida’s heat is expected to persist. Caracozza shares that while there will be a slight cool-down compared to previous weeks, temperatures will still hover in the high 80s to around 90 degrees due to persistent southeasterly winds and substantial cloud cover.
“We probably will be cooler, whatever cooler means in September, early September, but we’ll be cooler,” Caracozza said. “But still summertime heat.”
Key Takeaways for Labor Day Weekend Activity Planning
- Expect hot and humid conditions with feels-like temperatures up to 108°F.
- Bring umbrellas and plan for rain showers and thunderstorms, especially from Friday through Monday in Miami-Dade and Broward.
