What effect does "a bit of rain" have on the grass courts of Wimbledon?

Question

Do these changes favor Nadal's or Federer's game?

Answer 1

the effect, the game was temporarily posponed of the game. maybe it is favor to roger federer to think what's he gonna want to do in finals. strategy to defeat nadal in this series.

Answer 2

As the court is shaved almost to the grass roots, a wet court tends to make footing quite insecure for a player -  a big, heavy player, in particular.    (Spikes used to be worn at one time, but I don't know if they are allowed nowadays.)

The ball tends to bounce a little lower after hitting a damp lawn court, and the bounce becomes less predictable, as well.    A vigorous 5 set match on a lawn court that is wet can do a lot of damage to the court, and it certainly endangers the players.

Because the air above such a court is generally quite 'heavy' (humidity!), a sliced or top-spun ball moves a lot in the air before it bounces.  

  In general, a wet court plays considerably 'slower' than normal.   Even so, perhaps because of the diffult bounce (?), a volleyer seems to do better on a damp court than a baseliner.   I would imagine that dampness might favour Federer.

Answer 3

The wet grass plays very fast. I assume you're talking about a little rain that wets the grass before they can put the covers on. The surface then gets lightning fast. We saw that in Fed vs Roddick 2004. Roddick's serve was going crazy off the surface.
