Ever tried driving from Boise to Lewiston and realized your watch is suddenly an hour behind? It’s a trip. You’re still in the same state, yet you’ve somehow "gained" an hour just by crossing a bridge in Riggins. Most people assume states stick to one time zone, but Idaho is famously stubborn about its boundaries.
The time in Lewiston Idaho is dictated by the Pacific Time Zone, while southern cities like Boise and Twin Falls operate on Mountain Time. It isn't just a quirk of geography; it’s a reflection of how this town has always looked toward the coast rather than its own state capital.
The Great Idaho Time Split
If you look at a map, the line dividing the state is messy. It follows the Salmon River—specifically the "River of No Return"—which acts as a natural barrier. In Lewiston, you’re on the same clock as Seattle, Portland, and Los Angeles.
Why? History.

Back in 1918, when the federal government started formalizing time zones to keep trains from crashing into each other, they realized Northern Idaho was economically tied to the Pacific Northwest. The timber, the river trade, and the railroads all flowed toward the coast. If Lewiston had been forced onto Mountain Time, it would have been out of sync with its biggest business partners.
Honestly, the people in the panhandle didn't want to change. When southern Idaho moved to Mountain Time in 1920, the folks up north basically said, "No thanks." They stayed put on Pacific Time, and they've stayed there ever since.
Current Time and Daylight Saving in 2026
Right now, Lewiston follows Pacific Standard Time (PST). Like most of the country, it still plays the "spring forward, fall back" game. For 2026, the dates are already locked in:

- March 8, 2026: Clocks move forward one hour at 2:00 AM (Pacific Daylight Time begins).
- November 1, 2026: Clocks move back one hour at 2:00 AM (Pacific Standard Time returns).
It’s kind of a hassle for locals who commute across the state, but you get used to it. The sun sets significantly later in the summer here than it does in the eastern parts of the state. In July, you can often see light on the horizon well past 9:00 PM.
The Banana Belt Effect
You can't talk about time in Lewiston without talking about the "Banana Belt." Because Lewiston sits at a much lower elevation than the surrounding Palouse or the mountains to the east, it feels like a different climate zone.
Winter days feel shorter because the sun drops behind the steep canyon walls early. However, because it's Pacific Time, that "extra" hour of evening light in the summer makes the 100-degree days feel even longer.

- Summer Solstice (June): Expect about 15 hours and 43 minutes of daylight.
- Winter Solstice (December): Daylight drops to just under 9 hours.
Navigating the Time Zone Bridge
The most famous spot for "time travel" is the bridge over the Salmon River in Riggins, Idaho. If you’re heading north toward Lewiston, you cross that bridge and instantly go back an hour.
If you have a meeting in Lewiston but you're coming from the south, you've basically got a built-in "oops" buffer. You can leave Boise at 8:00 AM, drive for five hours, and arrive in Lewiston before 1:00 PM local time. It’s a weird mental gymnastic every traveler has to perform.
Practical Tips for Managing Lewiston Time
If you’re planning a trip or doing business here, keep these things in mind:
- Check Your Phone: Most smartphones are pretty good at GPS-based time updates, but in the deep canyons between Riggins and Lewiston, cell service can be spotty. Your phone might get "stuck" on Mountain Time until you hit a tower closer to town.
- The "North Idaho" Identity: People here identify with the Pacific Northwest. When they say "noon," they mean Seattle noon.
- Shipping and Logistics: If you're shipping goods from Lewiston to Boise, remember the destination is an hour ahead. A "next day" delivery can feel a lot tighter when you lose that hour during transit.
Basically, the time in Lewiston Idaho is a permanent reminder of the town's history as a river port. It was the first capital of the Idaho Territory, but it has always marched to the beat of its own drum—and its own clock.
Actionable Next Steps:
If you're traveling through the region, manually set a "dual clock" on your phone for both Boise (Mountain) and Lewiston (Pacific) to avoid missing hotel check-ins or dinner reservations. For those moving to the area, verify that your digital calendar settings are set to America/Los_Angeles rather than Boise's timezone to ensure your virtual meetings sync correctly.
