The Georgia Aquarium opens at 10 a.m. most days, but hours shift by season
The Georgia Aquarium in Atlanta opens at 10 a.m. on weekdays and weekends during peak season (roughly March through August), though closing time varies between 5 p.m. and 7 p.m. depending on the day. During slower months, the aquarium may open at 10 a.m. but close earlier, sometimes at 5 p.m. The exact schedule changes several times a year, so checking the official website or calling ahead before you go is the fastest way to confirm hours for your specific date.
Hours also shift around holidays. The aquarium stays open most major holidays but may adjust opening or closing times. Some special events or maintenance days can close the building entirely, though these are announced weeks in advance on the aquarium's website and social media.

Peak season versus off-season hours
From March through August, the Georgia Aquarium typically operates from 10 a.m. to 7 p.m. on most days, with some variation depending on whether it is a weekday or weekend. This is when school is out or about to be out, and attendance is highest. Weekend hours during this period are usually the longest.
From September through February, hours contract. Opening time remains 10 a.m., but closing time often drops to 5 p.m. or 6 p.m. on weekdays. Weekends may stay open until 6 p.m. or 7 p.m. even in the slower months. January and February tend to have the shortest hours of the year.
How to check hours before you go
The Georgia Aquarium's official website has a calendar where you can click any date and see that day's opening and closing times. This is the most reliable source because it updates when ready if hours change due to weather, special events, or other reasons.
You can also call the main aquarium number to speak with someone directly. If you are planning a visit more than a few weeks out, the website calendar is faster. If you are going within the next few days, a phone call confirms whether anything unexpected has shifted the schedule.
Holiday and special event hours
The aquarium remains open on most major holidays, including Thanksgiving, Christmas, New Year's Day, and Independence Day. However, hours on these days are often different from the regular schedule — sometimes shorter, sometimes longer depending on expected crowds. The website calendar marks holiday dates clearly and shows the specific hours for each one.
Special events like summer camps, evening programs, or temporary exhibits may extend hours on certain days or require separate tickets. These are announced on the aquarium's website and social media accounts weeks in advance, so you will see them when you check the schedule.
What to know about last entry and closing time
The closing time listed on the website is when the aquarium stops admitting new visitors, not when everyone must leave. Last entry is typically 30 to 60 minutes before the posted closing time, depending on the day. If the aquarium closes at 7 p.m., you may not be able to buy a ticket after 6 p.m. or 6:30 p.m.
If you plan to spend several hours inside, arrive at least two hours before closing. This gives you time to see the major exhibits without rushing. During peak season weekends, arriving early in the day is also wise because the aquarium can reach capacity and temporarily stop selling tickets.
Seasonal patterns and best times to visit
Spring and summer bring the longest hours and the most crowds. If you prefer shorter lines and a quieter experience, visiting on a weekday in fall or winter means you can still see everything, but you will have more space to move through exhibits. The trade-off is that you have less time in the building because hours are shorter.
Rainy days and weekday mornings are typically slower. If you check the weather forecast and see rain predicted, a weekday visit during that time often means shorter waits at popular tanks and exhibits. The aquarium is indoors, so weather does not affect your experience once you are inside.
Frequently Asked Questions
Does the Georgia Aquarium ever close completely?
Yes, but rarely and only for scheduled maintenance or severe weather. These closures are announced at least two weeks in advance on the website and social media. The aquarium has not had unplanned closures in recent years except during the pandemic.
Can I stay inside after closing time if I am already there?
No. Staff begin clearing the building before the posted closing time. If you are still inside, you will be asked to leave. Arriving at least an hour before closing gives you time to see what you came for without being rushed out.
Are there different hours for members versus general admission?
Members sometimes get early entry on certain days, but closing time is the same for everyone. Check your membership details or the website to see if early access is included with your membership level.
What time should I arrive to avoid crowds?
Weekday mornings right at opening (10 a.m.) are usually quietest. Weekends and afternoons after 2 p.m. tend to be busier. During summer, arriving before noon gives you the best experience with shorter lines at popular exhibits.
Do hours change for school holidays or spring break?
Yes. During spring break and other school holidays, hours extend to match peak-season times even if they fall outside the normal March-August window. The website calendar reflects these changes, so check it for the specific week you plan to visit.
