MIAMI · JULY · THE MONTH GUIDE
You have already picked Miami. July sets the shape of each day: a morning in the water, a middle spent in the shade or indoors, and an evening back outside once the sky has cleared. Summer humidity in South Florida runs between 85 and 90 percent, and afternoon thunderstorms come with the season. Plans that leave the hours from lunch to late afternoon flexible hold up best.
In return you get a warm sea and long, bright evenings. Miami Beach, home to South Beach and Lummus Park, is a separate city from the City of Miami across Biscayne Bay. Free transit runs on both sides, and $2.25 buses cross the causeways between them. Our Florida getting-around guide covers the routes in full.
MIAMI IN JULY · AT A GLANCE
Go for the water: an 88.2°F sea, long evenings and less rain than June or August, as long as the midday hours move indoors and the booking stays refundable.
HURRICANE SEASON: JUN 1–NOV 30 · SEA 88.2°F · SUNSET 8:15 P.M. ON JULY 15
Go for: morning and evening swims, free Thursday evenings at the Perez Art Museum Miami, and a sea that stays in the upper 80s.
Think twice before: booking non-refundable inside the hurricane season, or planning long midday walks at a 90.6°F average high.

July sits inside the Atlantic hurricane season. NOAA’s National Hurricane Center dates it from June 1 to November 30, puts the peak on September 10 and places most activity between mid-August and mid-October, so July falls early in the window. Book rates you can cancel, watch the tropics in the week before you fly, and read our Florida safety guide for storm preparation.
Miami weather in July: average highs, lows and rain days
| July normal (1991–2020) | Miami International Airport |
|---|---|
| Average high | 90.6°F (32.6°C) |
| Average low | 77.5°F (25.3°C) |
| Precipitation | 7.36 in |
| Days with 0.10 in or more | 11.1 |
| Days with 1 in or more | 2.2 |
| Daylight, July 15 | About 13 h 38 min |
| Sunrise / sunset, July 15 | 6:38 a.m. / 8:15 p.m. EDT |
Every air figure here comes from the official 1991–2020 normals that NOAA’s National Centers for Environmental Information publish for station USW00012839, the thermometer at Miami International Airport. July averages a high of 90.6°F (32.6°C), a low of 77.5°F (25.3°C) and 7.36 inches of rain. That is a real station on the mainland, not a reanalysis grid cell, and beaches on the barrier islands across Biscayne Bay can read slightly differently. We found no station normal for Miami Beach itself, so we give none.
On 11.1 days of an average July, the airport gauge records at least a tenth of an inch of rain, a little more than one day in three. A proper downpour of an inch or more comes about twice a month, on 2.2 days. Summer rain in Miami tends to arrive as an afternoon thunderstorm, so put the beach in the morning and keep an indoor option ready for mid-afternoon.
Only 13.1°F separates the average high from the average low. A night that bottoms out at 77.5°F calls for no sweater outdoors. Pack light, breathable clothes, a compact rain shell or umbrella for the storms, one thin layer for air-conditioned museums and restaurants, and a refillable water bottle.
On July 15 Miami gets about 13 hours 38 minutes of daylight, according to sunrise-sunset.org. The sun rises at 6:38 a.m. and sets at 8:15 p.m. Eastern Daylight Time. A beach walk at dawn and a swim after 7 p.m. both happen in full light, and an 8 p.m. dinner reservation still starts before sunset.
Can you swim in Miami in July? Sea temperature
Open-Meteo’s Marine service puts the sea surface off Miami at 88.2°F in July, averaged over 2015 to 2024. The figure is a mean of daily maxima: each day’s warmest reading, then averaged. A 24-hour mean comes out a shade lower, so a sea-temperature site quoting a slightly cooler July number is measuring a different thing.
Getting in at 88°F involves no shock, since the water sits only 2.4°F below the air’s 90.6°F average high. A noon swim cools you less than a winter one, so use the water as a morning and evening habit, with shade and drinking water on the sand in between. Stick to lifeguarded beaches such as Lummus Park, and treat the midday sun as the limit on a beach day.
We found no wind or swell data for July, so we give no wave or surf figure. The hurricane season is the variable we can date: a tropical system offshore can change sea conditions within a day. Check the marine forecast each morning and follow the lifeguard flags.
How busy is Miami in July? Crowds and prices
Hotel-market data relayed by travel guides puts Miami’s highest room rates in February through April and the lowest in August through October. July sits between those two windows. The trend comes from market reporting and is not an official statistic, and we found no monthly rate or occupancy series, so we put no ranking on July beyond that.
We found no series on booking lead times, so we give no count of weeks. Two choices shape the booking instead: the airport and the base. Miami International is about 12 miles from South Beach, 20 to 45 minutes by road depending on traffic. Fort Lauderdale-Hollywood is about 25 miles away, 35 to 50 minutes on I-95. Both drive times are indicative. Our Florida flights guide compares the airports, and where to stay covers the bases.
Miami-Dade County levies a 6.0% transient rental tax, filed and paid together with Florida’s 6% state sales tax, so those two lines add 12% to the room rate. We could not verify any further municipal levy, so we give no other percentage. Miami Beach hotels also commonly add a nightly resort fee. Published amounts diverge sharply, from about $25 on average to $35 to $95 at some properties, so read the fee line before you pay. Our Florida trip-cost guide builds a full budget.
A refundable room is the upgrade that changes a July trip. Paying extra for free cancellation keeps the option to move the dates if a storm forms in the Atlantic during the June 1 to November 30 season. Check how many hours before arrival the free cancellation ends, and apply the same test to the flight.
Things to do in Miami in July
In July the sea is warm enough for a swim at 7 p.m., and there is still light to walk back from it. That pairing disappears in winter, when the sea off Miami averages about 72°F by the sources we read, with January values ranging from about 72°F to 76°F depending on the table. The evening swim is the July habit to build a trip around.
Vizcaya Museum and Gardens stands in north Coconut Grove, inside the City of Miami, overlooking Biscayne Bay, a few minutes’ walk from the Metrorail station of the same name. It opens Wednesday to Monday at 9:30 a.m., takes last admission at 4:30 p.m. and closes on Tuesdays. Adults pay $20 during restoration work (usually $25), children 6 to 12 pay $5 and under-6s enter free. South Pointe Park is free to enter, with a public lot from $2 an hour and a $20 flat rate on weekends and holidays. Crandon Park on Key Biscayne charges $7 to park on weekdays and $10 at weekends.
The gardens at Vizcaya are open-air, so the 9:30 a.m. opening beats the early afternoon, when summer thunderstorms tend to build. Beach parking follows the week: South Pointe’s lot switches to its $20 flat rate on Saturdays and Sundays, and Crandon adds $3 at weekends. A weekday beach day keeps both bills down. More ideas across the state live in our Florida things-to-do guide.
Lummus Park, the beach fronting Ocean Drive between 5th and 15th Streets, is free and open 24 hours, with lifeguards, public restrooms and picnic tables. The Perez Art Museum Miami is free from 5 to 9 p.m. every Thursday, a window that opens more than three hours before the 8:15 p.m. sunset and closes about 45 minutes after it. It is also free all day on the second Saturday of each month, with art-making from 11 a.m. to 3 p.m. The Metromover in Downtown and Brickell and the Miami Beach trolley, running 8 a.m. to 11 p.m., cost nothing.
Miami in July: a two-day itinerary
Day one stays on Miami Beach. Be in the water at Lummus Park soon after the 6:38 a.m. sunrise. From 8 a.m. the free trolley runs about every 20 minutes on five routes, including the Collins Express along Collins Avenue. Spend late morning to mid-afternoon indoors or in shade, the stretch when storms tend to form. Around 6 p.m., head to South Pointe Park (free entry, lot from $2 an hour) for a second swim, and stay for the 8:15 p.m. sunset.
Day two crosses the bay. Take the Route 120 Beach MAX over the MacArthur Causeway to the Downtown Bus Terminal ($2.25, with free transfers to Metrorail) and ride to Vizcaya station for the 9:30 a.m. opening. On a Tuesday the estate is closed, so swap the two days. Give the gardens the morning and move indoors for the early afternoon. If storms settle in, finish at the Perez Art Museum Miami, free from 5 to 9 p.m. on Thursdays. If the sky clears, drive to Crandon Park on Key Biscayne ($7 to park on weekdays, $10 at weekends) for the evening swim.
Miami in July vs June and August
| Normal | June | July | August |
|---|---|---|---|
| Average high (NOAA 1991–2020) | 89.3°F | 90.6°F | 90.7°F |
| Average low (NOAA 1991–2020) | 76.3°F | 77.5°F | 77.7°F |
| Precipitation | 10.51 in | 7.36 in | 9.58 in |
| Days with 0.10 in or more | 12.6 | 11.1 | 13.3 |
| Sea surface, mean of daily maxima | 85.4°F | 88.2°F | 88.3°F |
Air temperature barely moves across the three months: the average high climbs from 89.3°F in June to 90.6°F in July and 90.7°F in August, and the low goes from 76.3°F to 77.5°F to 77.7°F. July has the least rain of the three. Its 7.36 inches compare with 10.51 in June, the wettest month of the year at the airport gauge, and 9.58 in August. Its 11.1 days of measurable rain also sit below June’s 12.6 and August’s 13.3. The sea warms from 85.4°F in June to 88.2°F in July, then holds at 88.3°F in August.
Moving four weeks earlier into June brings 3.15 more inches of rain, 1.5 more wet days and a sea 2.8°F cooler, for highs just 1.3°F lower. Moving four weeks later into August adds 2.22 inches and 2.2 wet days for the same sea, and it enters the August-to-October stretch that hotel-market reporting names as the lowest-rate period. Late August also falls inside the mid-August to mid-October window when NOAA’s National Hurricane Center records most activity. Our Miami in June and Miami in August guides go month by month.
Is July a good time to visit Miami?
Yes, if the trip is about the water: a sea averaging 88.2°F, long evenings and less rain than June or August. No, if the plan is long days on foot through Wynwood, Little Havana or Coconut Grove, where you face a 90.6°F average high, humidity of 85 to 90 percent and afternoon storms. Families tied to school dates can make July work by moving outdoor time to the morning and the evening.
If the answer is no, aim for December through April, the warm, dry stretch in South Florida, when temperatures run roughly 65°F to 80°F. Statewide the dry season starts in November, but Miami’s comfortable window opens a month later. Hotel-market reporting puts the highest rates in February through April, and December and January sit outside that peak. Our Florida best-time guide weighs all twelve months.
Of June, July and August, only July pairs a sea above 88°F with a rain total under 8 inches at the Miami International gauge.
The last word
Book the refundable room, put the beach at both ends of the day, and the rest of a July trip follows. Arriving at MIA, you can reach the sand without a car: Route 150, the Miami Beach Airport Express, leaves the airport Metrorail station about every 30 minutes from about 5 a.m. to midnight, seven days a week. It crosses the Julia Tuttle Causeway to Mid Beach for $2.25, and its buses carry luggage racks.
