How Much Earlier Is Seattle Than Miami?

Miami is three hours ahead of Seattle.

Seattle follows Pacific Time, while Miami uses Eastern Time. In August 2026, Seattle observes Pacific Daylight Time (PDT, UTC−7) and Miami uses Eastern Daylight Time (EDT, UTC−4), producing a three-hour difference.

For example, 10:00 AM in Seattle = 1:00 PM in Miami

During standard time, Seattle switches to Pacific Standard Time (UTC−8), while Miami changes to Eastern Standard Time (UTC−5).

Because both cities normally change their clocks according to the same U.S. daylight-saving schedule, Miami remains three hours ahead.

The time-zone difference can make the journey appear longer when comparing the local clocks. A six-hour flight leaving Seattle at 9:00 AM, for example, could arrive in Miami at around 6:00 PM local time even though the actual journey has lasted about six hours.
