Bottas said Mercedes has suffered "quite a bit with graining" in the cooler conditions in the morning and late afternoon in testing.
While he believes other teams are encountering the same problem, he said it is "quite difficult to learn anything on the car" when that occurs.
"There's a very small window to get the tyres to work," Bottas added.
