Miami is the biggest city in South Florida. It has a subtropical climate, which means the summers are hot and humid, the winters are mild and slightly chilly, and it's the perfect temperature for palm trees to grow all year round. The weather in Miami doesn't vary much from season to season unlike in the rest of the United States. 

South Florida is typically a sought-after destination during the winter when it's warmer than most of the country and has very little rain.

Although Floridians may find it chilly, vacationers during the winter can still enjoy sunny beach days, dining alfresco and a whole slew of outdoor activities. Summer's humidity and high temperatures tend to be a drawback for tourists to travel to Florida, let alone South Florida, but Miami's picturesque beaches always attract a crowd. 

The lowest recorded temperature in Miami is 30 F, although it rarely falls below 40 F at night. Much of the winter sees daytime highs between 65 and 75 F, and it doesn't get more perfect than that. The average low temperature in January, the coldest month, is 59.5 F. Summer is hot and humid, with daily highs in the upper 80s to low 90s F, with the temperature rarely falling below 75 F at night.

Miami receives about 60 inches of rain annually, most of that during the rainy season from May through September, with the wettest months June, August, and September.

The driest are December, January, and February.

The warmest ocean temperature along the U.S. coast during the winter is in Miami, where the water temperature is a pleasant 71 F in January.  In July, it's 86 F. You can swim in the ocean no matter what time of year you visit Miami.

What to Pack

You essentially need the same type of clothing no matter when you travel to Miami: Short-sleeved tees and shirts, shorts, beachwear, sunglasses, lightweight pants, sandals, and closed canvas shoes. If you visit during the winter you should also take a lightweight sweater, jacket, or pashmina for evenings, along with closed-toes shoes that are a bit dressier than canvas for evenings out. You should take an umbrella, rain jacket, or rain poncho if you are planning a summer visit when you can expect thunderstorms more days than not.
