What makes this route bumpy (or not)

On a long-haul flight like this, conditions change en route — a bumpy hour and a glass-smooth hour in the same trip is completely normal.

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–EZE 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 EZE flight usually turbulent?
It varies day to day with the winds aloft. On a long-haul flight like this, conditions change en route — a bumpy hour and a glass-smooth hour in the same trip is completely normal. Check the live forecast on RideScore just before you fly — it samples the actual forecast winds along the Seattle–Buenos Aires route at cruise altitude.
How long is the flight from Seattle to Buenos Aires?
The great-circle distance is about 11,130 km (6,912 miles), which works out to roughly 13h 36m 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.
