Seattle is on Pacific Time, currently UTC-8 in winter and UTC-7 in summer

Seattle observes Pacific Standard Time (PST) from early November through mid-March, which is 8 hours behind Coordinated Universal Time. From mid-March through early November, the city switches to Pacific Daylight Time (PDT), which is 7 hours behind UTC. The exact dates shift slightly each year because the United States changes clocks on the second Sunday in March (spring forward) and the first Sunday in November (fall back).

If you're calling the Seattle Aquarium or planning a visit, knowing the current time there matters for ticket purchases, show times, and reaching staff during business hours. The Aquarium is open daily from 9:30 a.m. to 5 p.m. Pacific Time, though hours may vary seasonally or for special events.

Key Takeaways

  • The Seattle Aquarium operates from 9:30 a.m. to 5 p.m. Pacific Time daily, though you should confirm current hours before visiting.

How to find the exact current time in Seattle

The simplest way is to search "current time in Seattle" on any search engine, which displays the live time in Pacific Time. Your phone's clock app also has a world clock feature—on iPhone, open the Clock app and tap the World Clock tab, then add Seattle; on Android, open the Clock app, go to World Clock, and tap the plus sign to add a new city.

If you need to call the Aquarium directly, their main number is (206) 386-4300. Staff can confirm whether they're currently open and answer questions about visiting hours or special programs. Calling during business hours (9:30 a.m. to 5 p.m. Pacific Time) gives you the fastest response.

Time differences between Seattle and other US regions

Seattle is three hours behind the East Coast (Eastern Time), two hours behind the Central Time zone, and one hour behind Mountain Time. So when it's noon in Seattle, it's 3 p.m. on the East Coast, 2 p.m. in Chicago, and 1 p.m. in Denver. These differences hold whether daylight saving time is in effect, because all US time zones shift on the same dates.

If you're coordinating with someone in another time zone—say, booking a video call with family on the East Coast—subtract or add hours accordingly. A helpful trick: when Seattle switches to daylight time in March, all other US zones do too, so the hour difference stays the same.

When Seattle observes daylight saving time

Every year, Seattle "springs forward" at 2 a.m. on the second Sunday in March, moving clocks ahead one hour. This means 2 a.m. becomes 3 a.m., and the day is one hour shorter. In fall, on the first Sunday in November, the city "falls back" at 2 a.m., moving clocks back one hour so 2 a.m. becomes 1 a.m., and the day gains an hour.

During the spring transition, some people find it harder to wake up for morning activities like visiting the Aquarium. During the fall transition, you gain an extra hour of sleep. Neither change affects the Aquarium's posted hours—they stay the same on the clock, just the sun rises and sets at different times.

Planning your Seattle Aquarium visit across time zones

If you're traveling to Seattle from another time zone, arriving a day or two early helps your body adjust. The Aquarium is located at Pier 59 on the Seattle waterfront and is busiest mid-morning and early afternoon. Booking tickets online in advance lets you choose your entry time and avoid lines.

When you book online, the website shows times in Pacific Time automatically if you're booking from Seattle's Aquarium site. If you're booking from elsewhere, double-check that you're reading the correct time zone—the confirmation email will show the time in Pacific Time, which is what matters for your actual visit.

Why Seattle's time zone matters for planning

Seattle's Pacific Time zone is one hour behind the Mountain West and three hours behind the East Coast, which affects everything from phone calls to live events. If the Aquarium hosts a live feeding demonstration or special talk, the posted time is always Pacific Time. Streaming events or virtual tours are also scheduled in Pacific Time unless otherwise noted.

For out-of-state visitors, setting a phone reminder for 30 minutes before your Aquarium entry time (in your home time zone) helps you stay on track. Many visitors forget to account for the time difference and arrive an hour late, which can mean missing reserved entry slots or paying for a later time.
