What makes this route bumpy (or not)

Part of this route runs through the tropics, where the main turbulence driver is convection — building storm clouds, especially in the afternoon and in the wet season. Crews routinely deviate around the buildups, so brief detours are 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 EZE–SJU 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 EZE to SJU flight usually turbulent?
It varies day to day with the winds aloft. Part of this route runs through the tropics, where the main turbulence driver is convection — building storm clouds, especially in the afternoon and in the wet season.

Check the live forecast on RideScore just before you fly — it samples the actual forecast winds along the Buenos Aires–San Juan route at cruise altitude.
How long is the flight from Buenos Aires to San Juan?
The great-circle distance is about 5,975 km (3,710 miles), which works out to roughly 7h 32m 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.
