Interesting. I have been studying especially the tides and directions for the past months as I have become pretty good predicting conditions in a mix of webcams between 2 spots far apart on the island, websites and experience of past swells. But there is one thing thats for sure: If you want to be sure about the conditions you got to drive to the beach and take a look. And sometimes even that can fool you. It's one thing to watch it from the beach and another to step into the water and see the waves from sea level and closer to them. But as Surfline here said before me, I thought it must be common sense that an incoming tide is supposed to generate bigger and better waves since more water get pushed towards the land and when the tide is getting low, obviously the water goes back and the waves should get smaller. But every day and spot is different.
