Not sure this "makes someone a better hitter", but it has started to heat up in Central VA with the temps in the upper 80's, and this has caused the ground to harden a little. Last night in one game (make up), our team had three hits bounce over a 315 fence for a ground rule double. The interesting thing that I don't know that I have seen before, was on a liner to left, the ball took one normal hop and then a +/-20' hop over the fielder and fence. There were multiple high hops in the OF that were above "norm" from past experience.
RE: Waiting on better pitches: That all depends on the league, your team mates and the ump. I can say that the instances of an ump calling a ball a foot off the plate a strike in order to try and "move along the game" when the pitchers are struggling with the new ball in the wind have increased substantially. It doesn't effect the better players in the top league, but I am surprised that we are over a month in and pitchers are still battling to throw consistent when the wind is up. After a number of generous strike calls, one ump said, "I get paid by the out"....LOL. It makes it difficult to wait on a better pitch when the umps are expanding the zone (and the good pitchers take advantage of this!).
