No signs of our new NW swell on Buoy 01 yet and it looks likely that we’ll see small/slow surf for most of the morning. We expect the swell to start building by midday and really come on over the afternoon and evening hours. We still expect a peak overnight and a gradual fade on Tuesday, although we’ll refine the exact details as we see this swell build on Buoy 01 in the next 12-24 hours. Monday afternoon is likely to favor Pipe on the building and longer period swell, with a mix of Pipe and Backdoor waves on Tuesday. Short-period ENE tradeswell will also be in the mix for some jumble, although that looks less problematic than the short-period N swell the past couple days.
Trades are expected to build on Monday as high pressure strengthens to the north of the islands. We expect strong ENE trades on Monday to continue Tuesday, although shifting to at least a slightly better direction (E to ENE). Trades should slacken a notch or two on Wednesday into the first half of Thursday and remain from a favorable E direction. Rebuilding ENE trades are likely Thursday afternoon/evening and Friday, becoming strong once again.
The next NW swell (305-330, peak energy around 315-325 degrees) for the end of the week is developing now and, thus far, the storm has actually out performed model guidance. We remain on track for another strong swell to build in through the morning on Thursday and likely peak in the afternoon before easing on Friday. Swell direction and period will favor Pipe Thursday morning, with Backdoor turning on more over the afternoon hours. As is noted above, it now looks like we could see a period of favorable to good wind Thursday morning, potentially the best of the week. It’s something we’ll continue to refine in the next day or two.
Friday is expected to see a fading trend in surf as strong ENE trades build.
