A quick guide to Aquarium of the Pacific operating hours

Weekdays are comparatively less crowded than weekends but there's still a chance that you'll see a huge number of visitors at every exhibit. Arrive in the later evening if you want to avoid school kids on their school trips as they usually happen on weekday mornings. During holidays and school vacations, you can expect to have a packed house even on the weekdays.

Weekends are filled with locals and tourists, especially families with school-going kids. You might avoid the worst of it if you arrive as soon as the aquarium opens, around 9 am. However, expect it to be quite a tight fit throughout the day.

The peak times for the Aquarium of the Pacific are the Summer months, the holiday seasons, and school vacation times, although it is a very popular spot throughout the year. June, July, and August tend to be the most crowded due to summer vacations, leading to longer wait times and more limited parking. However, with 5 acres of space, the aquarium can still accommodate visitors without feeling overly crowded.

There is hardly any low season but the wet months in California curbs some crowds in the aquarium, especially because of the frequent thunderstorms. October to February are, therefore, relatively quieter, with the exception of December due to the holiday season.
