What makes this route bumpy (or not)

This is a short hop, so a bigger share of the flight is spent climbing and descending through lower-altitude weather. Light bumps in the first and last twenty minutes are common and completely routine.

How the forecast works

RideScore reads the same global weather models professionals use (NOAA GFS / ECMWF via Open-Meteo), computes wind shear, jet-stream strength and storm energy at up to 11 points along the SEA–SFO great-circle, and turns it into a simple 0–10 bumpiness score for each leg of your flight — plus recent pilot reports from aircraft that just flew nearby. It's free, with no account and no tracking, and works up to 16 days ahead.

Common questions

Is the SEA to SFO flight usually turbulent?
It varies day to day with the winds aloft. This is a short hop, so a bigger share of the flight is spent climbing and descending through lower-altitude weather. Light bumps in the first and last twenty minutes are common and completely routine. Check the live forecast on RideScore just before you fly — it samples the actual forecast winds along the Seattle–San Francisco route at cruise altitude.
How long is the flight from Seattle to San Francisco?
The great-circle distance is about 1,093 km (679 miles), which works out to roughly 1h 47m in the air depending on winds and routing.
Is turbulence on this route dangerous?
No — turbulence is uncomfortable, not dangerous to the aircraft. Modern jets are built for far worse than anything encountered in normal service, and pilots route around the roughest air. Keep your seatbelt fastened and it is a non-event.
