IF AND WHEN HEALTHY...
If he can see the past, he can effectively predict the future.Two things come to mind that may imply he can see the future:
1. "I'm waiting for an old friend." He knew Jaime was on his way to Winterfell.
2. He gave Arya the Valyrian Steel dagger that she used to defeat the Night King.
Number one could just be he was watching where Jaime was in the present and happened to notice him on the road leading to Winterfell.
Number two could be random luck. Not really definitive either way.
