I live in NJ, my yard gets sun thru the day but trees create shade over the pool just at the time we get home from work, so any night swimming is in shade. The outside air gets a bit chilly when the sun is blocked - even on 90 degree days, it drops to the 70's in the shade. I can do some work to trim some branches and get a little more sun at night. My question is, should I??? Is it better to have the setting sun on the pool or is having shade an advantage??? Once I trim the trees, it can't be undone so I want to be sure it's the right move. I welcome any sun/shade feedback.
