Just what happens with the rain load during the peak growing season. Later in the summer it will switch to a more drought condition though and there won't be so frequent mowing. But the peak parts, yeah, not much I don't think you can do via strain selection given the quantities of rainfall.
Go ahead and try and mow that after its flopped over. Mower is going to choke with how much grass you are putting into it. You may need to weed wack it down and rake or blow it out before you can mow.
