Flight time & jet lag: Portland to Seattle

Portland to Seattle: Route overview

This short-haul route from Portland (PDX) to Seattle (SEA) covers 208 km in approximately 47m to 1h 09m. Since Portland and Seattle share effectively the same UTC offset, jet lag is not a factor, though the travel time itself can cause fatigue. Both cities sit at similar temperate latitudes, meaning daylight patterns will feel familiar upon arrival — a helpful factor for circadian adjustment.

What makes the Portland–Seattle route different

The specific combination of 208 km distance, 0-hour time difference, and north-south direction places this route in the light jet lag category. Compared to a same-distance route with fewer time zones crossed, the circadian challenge here is the dominant factor in post-arrival recovery.

Arrival strategy for Seattle

Arriving in Seattle without a time zone change means your body clock is aligned with the local schedule. Focus on staying hydrated during the flight, eating a meal on arrival at a local mealtime, and getting moderate physical activity to counter travel fatigue. Most people feel fully recovered after one good night's sleep.

Circadian rhythm analysis: Portland → Seattle

Your circadian rhythm remains synchronized with the local day-night cycle in Seattle since there is no time zone difference. The primary challenge is travel fatigue from the 47m to 1h 09m flight. Maintain your normal sleep schedule and prioritize hydration.

Pre-departure preparation

With minimal time zone change, no pre-departure sleep adjustment is necessary for this Portland to Seattle route. Focus instead on arriving well-rested: maintain your normal sleep schedule in the days before travel, stay hydrated, and avoid alcohol on the flight.

Your first 72 hours in Seattle

Day 1: Arrive in Seattle and follow local time immediately. Eat meals at normal local hours and get outside in daylight. Day 2: You should feel fully adjusted. Resume normal activities. Day 3: No residual effects expected.

Recovery timeline

No jet lag recovery needed for this Portland to Seattle route as both cities share the same time zone offset. Any fatigue should resolve after one night of good sleep.

Seasonal and climate factors

Short-haul flight times on this short-haul route are less affected by seasonal wind patterns, though winter weather can cause delays at both Portland and Seattle airports. Seattle at 47°N experiences moderate seasonal daylight variation. Summer offers longer evenings useful for westward adjustment, while winter's earlier sunsets support eastward adjustment schedules.

How the Portland–Seattle flight time is estimated

The 47m to 1h 09m estimate for Portland to Seattle is derived from the 208-km great-circle distance. As a short-haul route, a larger proportion of flight time is spent climbing and descending rather than at optimal cruise altitude, resulting in a lower effective speed of 650–750 km/h. An additional 30–50 minutes accounts for taxi, takeoff, climb, descent, approach, and taxi at both PDX and SEA. Actual routing through controlled airspace may add 3–8% distance beyond the great-circle path due to air traffic corridors and restricted zones along the way.

Wind patterns and flight duration

On this short 208-km route, wind effects are relatively minor compared to the fixed overhead of taxi, takeoff, and landing. The main variable in flight time is airport congestion and weather at PDX and SEA.
