Kugenuma Rivermouth Surf Forecast and Surf Report

Alright surfers, Rusty here. Let's take a look at what's coming our way.

Right off the bat, I gotta tell ya, it’s going to be a pretty flat start. For the first week or so, from now through the 24th of August, the waves are just not happening at Kugenuma Rivermouth. We’re talking tiny, weak stuff with poor conditions—the kind of day you leave the board in the car. It’s a long, quiet gap of about 8 days with no real surf to speak of, so don't bother paddling out until things change.

Now, if you’re patient, there’s a light at the end of the tunnel. Things start to get interesting around Tuesday the 25th. The swell starts to pick up from the SSE, but the conditions are still messy with onshores. You might get a wave, but it won't be worth rushing for.

The real standout arrives on Wednesday the 26th. The morning is the pick of the whole forecast. We’ve got a solid 6ft of SSE groundswell, and the period is a juicy 14 seconds, so these waves will have some real punch. The wind will be blowing offshore from the NNE, keeping things glassy and clean. The energy reading is a strong 1277—this is proper surf. The rip at the river mouth will be working, so the waves will have some shape to them. At this size, it’s not for beginners; the experienced crew will have a ball. As the afternoon rolls on, the wind swings more NE and picks up to a moderate breeze, but it stays offshore and still clean.

If you miss that, don't worry. Friday the 28th is another big day. We’re looking at 8ft of SSE swell with a 14-second period. The morning is the go with a light offshore breeze—absolutely perfect, clean lines. This is big, powerful stuff with energy readings up near 3009. This is strictly for experts, folks. The afternoon will get a bit bumpy with a cross-shore wind, so get out early.

Saturday the 29th is the biggest of the whole run, with 10ft of swell. The morning offshore wind from the NNE will make for some epic, though heavy, conditions. This is massive wave energy (4250), and only the most experienced charger should even think about it. Beginners, stay well clear.

After that, the swell drops back down fast on the 30th and 31st, and the onshores return, so the window is short and sweet.

In short: It’s a flat start, but the last week of August fires up. Wednesday morning the 26th is your best bet for clean, fun, mid-sized surf. Friday morning the 28th is the real standout for the experienced surfer looking for solid groundswell and clean conditions.

Rusty.
