Expect storms and large amounts of rainfall during September. Miami usually gets 5.7 inches of rain, 3-9 inches on average during this month. The rainfall will start to slowly decrease as the month goes on, but the rainy season isn’t finished yet.

💡 Hurricanes and tropical storms are prevalent this month as it is peak season, so expect heavier rains during this time at least until mid-September.

Can it rain the whole day? Rainfall won’t spoil your trip in September, as it usually doesn’t last long. We usually experienced an hour or two of precipitation on most rainy days during this month. However, it is the rainy season, so you might still expect a few long rainy afternoons that turn into night.

Heat/Humidity

Summertime lingers a little longer in Miami, including high humidity levels. In fact, September tends to bring the highest humidity levels of the year in the southern part of Florida, including the city of Miami.

The morning hours tend to have humidity levels of 88%, and the late afternoons have humidity levels on average of 66%. As The month goes on, levels will start to decrease by about 4%.

Tip: It is important to stay hydrated. When we explored the Miami area, we always brought a refillable water bottle to keep with us throughout the day.

September tends to stay consistent throughout the day, mainly being hot and muggy the majority of the time. It tends to cool off in the evenings or after rainfall, and winds start to become stronger in the evening hours as well.

Typical daily temperature progression in September:

  • Early Morning (6 AM): 79°F

Evenings: It is finally cooling off, and winds start to pick up later in the early evenings. Humidity stays low until around 4 am.

Water Temperature

This month tends to be the hottest and most humid month in Miami, and water temperatures follow.

Miami’s coastline brings warm waters during September that average around 85°F. These temperatures are ideal for water sports. and lucky for you, Miami has an abundance of options to choose from.

Hurricanes and tropical storms love warm water just as much as we do; keep this in mind when planning a beach vacation to Miami. It is important to take hurricane warnings seriously and be sure to take the necessary precautions to ensure safety in case of an emergency.

Packing Tips | September Outfit Guide

As Miami is such a free-spirited city, almost any style is acceptable and you will see a wide range of summer attire, especially around South Beach. Miami gives you a chance to wear the trendiest outfits and some of your favorite ‘go-to’ pieces.

During September, mornings and early afternoons are ideal for wearing shorts and t-shirts. Be sure to keep a raincoat handy or pack an umbrella for afternoon rain showers.

Summer tends to linger around a little longer down in Miami, so it’s still the season for flip flops, shorts, and shades.

Dressing for unpredictable weather in Miami tends to be difficult. From our personal experience with traveling around the Miami region during this time of year, keep an umbrella on hand at all times.

💡 September is still very hot and muggy, so try to stay away from tight-fitting clothing and wear loose-fitting items. Pack shorts, t-shirts, tanks, light sweaters for the evenings, and a raincoat. Bring shoes that you are comfortable getting wet in since rain showers happen daily.

During the month of September, the clothing items in your suitcase should consist of:

  • Shorts
  • Capris & Bermudas
  • T-shirts & Tanks
  • Sundresses
  • Light sweater (evenings)
  • Bathing Suits / Cover-up, Swim Trunks
  • Raincoat or Poncho

Wearing jeans will not feel great during the high daytime temperatures and extreme humidity. While your favorite jeans might make you feel sticky as you experience your day in Miami, we recommend choosing shorts or capris.

If you choose to wear jeans throughout the day, stay away from tight, skinny cuts and pack a looser and more breathable style instead. This will reduce your risk of heat-related illness and keep you comfortable.

Styling tip: Pair your loose boyfriend jeans with a thin tank or crop top and a flowy button-up top. This will give you a cool summer look while also protecting more of your skin from the sun.

Comfortable shoes are a must, no matter where you go. Don’t underestimate the amount of walking you’ll be doing.

Restaurant / Evening Tip

When visiting Miami, we always keep a sweater or light jacket handy throughout the day for dining out in indoor restaurants. Since the temperature outside is very hot, the air conditioners are on full blast.

If you are someone who tends to get cold easily, this is a great tip to keep in mind. But even if you are a perpetually warm person and always find yourself sweating, we suggest packing a sweater or cardigan – don’t underestimate the strong indoor air conditioning!

💡 Tip: If you get cold easily, you should absolutely pack a sweater. I personally never need a sweater when I’m indoors, and while many restaurants and stores will blast the air conditioning, sometimes places will be so busy or the doors will open so frequently that it won’t always be freezing inside.

But my mother, for example, is someone who is constantly cold and needs a sweater everywhere she goes, even in the height of summer!

Headache Meds

A travel tip that we have learned from traveling to the Miami area is to always bring some medicine for a headache. The Florida heat is no joke, and if you aren’t used to a warm climate, this could really bring a damper to your visit.

Another great solution for a heat-induced headache is to drink electrolytes like Liquid IV powder, which is portable and works fast to hydrate your body. You should drink it during the day to stay hydrated and prevent a headache in the first place.

Make sure to pack a fanny pack or small backpack in your luggage for your Miami trip. This is a good idea to keep your hands free and your belongings on your person whether you’re having a beach day or spending some time at the theme parks.

Before starting each day on your trip, make sure you stock your bag with a refillable water bottle, poncho, sunscreen, a phone charger, and hand sanitizer.

Tip: If you don’t plan on returning to your hotel for most of the day, pack your bag with a swimsuit, a similarly styled change of clothes, and spare flip-flops to be ready for whatever the afternoon brings.

Sun Protection Is Important

Remember that Florida is the southernmost state in the USA. This means that the sun’s rays strike the state at a higher angle, which increases its ability to heat in the summer and winter.

A strong sun combined with staggering humidity levels can be particularly shocking for people who aren’t used to it, and increases the risk of heat-related illness.

Avoid tight, compressive, and non-breathable clothing, especially during the daytime. Fall clothes like layers and jackets should stay out of your suitcase.

UV ray protection is just as important as heat protection. If you plan on wearing clothing that reveals a lot of skin to keep as cool as possible, remember to apply and reapply sunscreen with an SPF of 30 or higher to prevent burning. Also, keep a hat and sunglasses handy!

Tip: Applying sunscreen in the morning before your Florida excursions won’t be enough if you plan on being out all day. Reapply at least every two hours, especially if you are sweating or getting your skin wet.

Personal Experiences and Tips

Check your SPF: Make sure you don’t buy sunscreen with low SPF and wear it all day when staying outside.

I didn’t notice the SPF on the bottle, thinking any sunscreen would do. My skin was so red and sensitive by nighttime after my first day walking around the parks. I couldn’t understand why I was so burnt until I looked it up and realized the SPF I used was half the recommended amount.

The next day, I had to cover up with a hat and a thin long-sleeved shirt to protect my raw and peeling skin. It was very warm and uncomfortable but I had no choice – I won’t be making that mistake again!

Prepare your hair for humidity: If you have long hair, bring extra headbands or hair ties. The humidity will make it feel like your hair is glued to your neck and forehead, and I couldn’t believe how frizzy my curls got no matter how much product I put in them.

I needed to keep my hair in a bun or in a ponytail most of my trip, and I don’t know what I would have done without extra scrunchies and some gel in my suitcase.

Pack more than one bathing suit and cover up, since the warm weather will be great for multiple beach and pool trips.

Beach tip: If you visit the beach and have plans in the area afterwards, most establishments in close proximity to a beach are swim-attire-friendly.

Always double-check, but you shouldn’t have any problems if you want to grab a bite to eat after the beach in a swimsuit and cover-up or T-shirt and swim trunks.

Essential Packing List for Women
  • Tank tops
  • Loose shirts
  • Sundresses
  • Loose or sweat-wicking shorts
  • A light jacket or sweater
  • Comfortable walking shoes
  • Flip flops for the beach
  • Strappy sandals or heels for a night out
  • Sunglasses

Chic sunglasses can add an extra “wow” element to any outfit. Bring a hat that is stylish but practical in keeping your face protected from the sun. If you want to keep it more casual, a baseball cap can work just fine.

Jewelry

As for jewelry, less is more during the day. Stick to simple chains with a secure clasp, especially if you plan on going in the ocean or on theme park rides. Avoid rings, earrings, or other pieces of jewelry that can get lost or caught on something.

At night, feel free to dress up your bling, especially if you’re exploring one of Florida’s big, bright cities!

💡 In Miami, no piece of jewelry is too much. Bring out your bold rings, statement necklaces, and fill your ears with bright studs and hoops!

Prepare Well for Your Night Out

If you plan to wear heels on a night out, bring a thick pair of socks in your bag. Since it won’t make sense to bring a pair of sandals in your clutch for your dinner outfit, this will give your feet a break and keep you from walking around barefoot.

This is especially true if you’re doing a lot of walking in the evening, like bar hopping or going to a concert.

Essential Packing List for Men
  • T-Shirts
  • Button-up shirts
  • Trousers
  • Khakis or cargo shorts
  • A light jacket
  • Comfortable walking shoes
  • Flip flops for the beach
  • Dress shoes for a night out
  • Sunglasses
  • A hat or baseball cap

A baseball cap or other hat would go well with such a casual outfit and protect your face from the sun. And don’t forget your sunglasses!

Safety Tip

Like with any area that is popular for tourists, keep your wits about you and be aware of your surroundings, especially if your bag, jewelry, or other belongings are easy to snatch.

Pay attention to where you are, who is around you, and keep track of your belongings at all times. You don’t want to put a kink in your vacation by having your things lost or stolen!

Conclusion

September can bring unpredictable weather in Florida, but you can definitely count on strong sunshine and stifling humidity. This means you should pack a poncho or small umbrella and one or two spare changes of clothing in case you get wet unexpectedly. Also make space in your suitcase for sunscreen and summer-appropriate clothing to stay safe and cool.

Beach Guide

A trip to Miami in September isn’t complete unless you spend a day or two at the beach. Miami has some of Florida’s warmest waters and most beautiful coasts. Depending on your preferences,  Miami offers a variety of possibilities for everyone. South Beach and Miami Beach are the two most popular beaches in the Miami area.

South Beach

This is one of the most popular beaches in the country and is loaded with restaurants, attractions, shops, and sights. It is a very welcoming, energetic, and trendy/upbeat city, so visitors shouldn’t be surprised by anything.

It is known for its thriving nightlife and abundance of bars and clubs on the strip.

Miami Beach

For visitors wanting a more relaxing and peaceful vibe on the beach, head north to Miami Beach. It is ideal for travelers who want to enjoy their time in Miami without all the craziness and upbeat energy that comes along with South Beach.

Crowds

Although South Beach and Miami Beach are the most popular beaches in Miami, there are numerous lesser-known and less-crowded parts of the shore in the Miami Beach area.

Thus, if you need some relaxation, you can often find a quiet location away from the crowds.
