Totally agree that "The Martian" would never happen in real life. Still, as other have pointed out, there are dust devils and "strong" winds.

"strong" is called a breeze.

Strongest martian storm can have wind speeds up to 100 km/h. Because low air density, the force of the wind would be equal to "Fresh breeze" in Beaufort Wind Scale. (8.5-10.5 m/s) "Small trees sway, waves break on inland waters."
