Hawai River Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are serving up for Hawai River.

Honestly, it’s a pretty lean run. The swell windows are there, but the conditions are going to fight you most of the time. We’ve got a bit of a gap to start, with no real surf on offer until later in the first week. Things start to flicker around the 8th, but it’s a real mixed bag.

For the first real standout, look to Tuesday afternoon, September 8th. We’ve got a 5ft swell rolling in from the NNW with a period of 9 seconds – that’s a solid groundswell with some grunt, and the combined wave energy is moderate at 387. The wind is swinging offshore from the south, which is going to keep things clean. This is your best chance for a proper session early on, but keep in mind Hawai River is an inconsistent point break, so you’ll need to be patient for the sets.

Wednesday the 9th is a write-off – glassy but with a tiny 2ft swell. The energy just isn’t there.

We then hit a long, frustrating stretch. From Thursday the 10th right through to the morning of Monday the 14th, it’s mostly small, onshore, or choppy. There’s a brief moment on the 13th with a 5ft swell and clean offshore winds from the southwest, but the wave quality is still just ordinary. The energy is only moderate (171). Not worth getting too excited about.

Tuesday the 15th is flat, and then we see a spike in size but not in quality. Wednesday and Thursday the 16th and 17th see the swell push up to 7ft to 7ft from the NW, but it’s accompanied by moderate cross-shore winds and chop. The energy is strong (315-429), but the conditions are poor. This is more of a kite-surfing setup than a clean paddle session.

The real highlight, and the one to circle on the calendar, is Monday, September 21st. This is the one. We’ve got a 8ft swell from the north with a very long period of 12 seconds. The combined wave energy is a powerful 1557 – that’s serious, deep-water energy. Now, a long-period groundswell like this can break a bit straight at a beach break, but at a point like Hawai River, it’s going to line up beautifully. The wind is a moderate cross-shore from the west, so it won’t be perfect, but the power in the water is undeniable. This is expert territory with that size – over 8ft it’s only for the experienced. This is a promising, but still a long-range call, so keep an eye on it.

Water temp is sitting at a typical 58°F, about average for this time of year.

Keep the stoke alive, check the forecasts, and be ready for that 21st.
