Weather InformationMiami has warm weather year-round; highs are almost always in the 70s and 80s. Even on cloudy days, a hat and sunblock are a must to prevent sunburn. Humidity is worse in the summer months and can be oppressive, especially to travelers used to dry heat. June has the least desirable weather, as it traditionally sees the most rainfall. All of Florida is located within the hurricane belt, so Miami is at risk for hurricanes and tropical storms between June 1 and November 30. To prepare for travel during these months, purchase travel insurance that covers you in the event of a hurricane and keep a close watch on the weather forecast prior to departure.
Crowd InformationThe entire city feels crowded during peak season, making the winter months best for people watching and worst for getting dinner reservations. Although hotels may sell out on summer weekends, you won't find crowds on the beach or at area attractions. South Beach operates on a late-night clock, so if you want to beat the rush at eateries and clubs, opt for an early entrance. The nightlife tends to heat up close to midnight; arrive any earlier and you're likely to be drinking alone.
Closure InformationThe beach is open for business year-round, as are hotels, restaurants, and attractions. However, hotels are constantly upgrading their properties, and you can expect they'll try to schedule any closures for renovations during the slow season.
When to SaveThe low-season summer months are the least expensive time to visit Miami, and at hotels, weekdays are usually cheaper than weekends. In the peak season, you may find small price breaks by traveling midweek rather than on the weekend, but prices tend to be high regardless. Dining and attraction prices fluctuate less with the seasons, but occasionally you'll find summer discounts or coupons intended to drum up business.
When to BookMany hotels sell out in advance on winter weekends, while in the summer, some hotels post hopeful "Vacancy" signs on Collins Avenue. The best rule of thumb is to book as far in advance as you can, especially if you have a specific property, location, or price range in mind. You might be able to get away with a last-minute booking in the off-season, but it's vital to book several months in advance during the winter. Also, room prices rise as the hotel fills up, so the earlier you book, the cheaper the room rate you'll pay.
