The swell will change direction throughout and have the most north in it on Friday. Look at how the low moves and develops relative to our beloved home state. Where I live in NJ, an 8' NE swell will look about 2' because of our southern exposure.
I heard that Swellinfo has the best forecast and focuses more on the east coast than Surfline or MSW. I had the surfline app, used it for two days, then on the way to RI one morning I got all bummed because surfline said 2 ft. Then I got there and it was head high and strong offshore winds.
