The following text is from Frances Hodgson Burnett's 1911 novel The Secret Garden. Mary, a young girl, is outside trying her new jump rope.

The sun was shining and a little wind was blowing--not a rough wind, but one which came in delightful little gusts and brought a fresh scent of newly turned earth with it. She skipped round the fountain garden, and up one walk and down another.

As used in the text, what does the word "rough" most nearly mean?
