Kugenuma Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a real good look at what’s coming down the pipe for Kugenuma Rivermouth. This is a 16-day forecast, so we’ve got a bit of a slow start, then a serious pulse of energy, and then a long quiet spell before things might get interesting again.

The first few days are a bit of a write-off. We’re looking at Saturday the 1st and Sunday the 2nd with tiny, weak swell. The water is sitting at 82°F which is a touch warmer than normal for this time of year, so at least the dip will be pleasant. But the waves are just not there. Monday the 3rd sees a bit of a lift, but it’s still small. The real story starts to build on Tuesday the 4th. The swell is coming from the SE, and the energy is climbing. By Wednesday the 5th, we’re looking at a standout. That’s the day to circle on the calendar. We’ve got a solid 8ft swell from the SSE with a clean 16-second period, and the wind is blowing offshore from the NNE. That’s a recipe for beauty. The wave energy is very strong (3834) and the afternoon only gets better with 10ft waves. This is serious, powerful surf. It’s over 8ft, so this is strictly for the experienced crew. Beginners, stay on the sand and watch the show.

Thursday the 6th keeps that quality going with another 8ft morning from the S and light winds. The energy is still very strong (3588). However, the wind swings onshore in the afternoon, so the window is the morning. After that, the swell drops and the wind gets messy. Friday the 7th and Saturday the 8th are a write-off with onshore winds and poor conditions.

Then we hit a long, dry spell. From Sunday the 9th all the way through to Saturday the 15th, the surf is tiny. The combined energy drops to weak to moderate levels, with most days showing poor to marginal conditions. It’s a real frustrating stretch of ankle-snappers and non-existent waves. The wind is often offshore, but there’s just no swell to work with.

Finally, on Sunday the 16th, we get a flicker of hope. The morning shows a 6ft SE swell with a 14-second period and a clean offshore wind. The energy is strong (1208) and it’s a promising end to the run. But it’s a long way out, so treat it as a hopeful rumour for now.

The one true standout of this whole 16-day window is Wednesday the 5th of August. 10ft, clean, powerful, and offshore. That’s the one. It’s a river-mouth setup, so that long period groundswell will hold up well. Be aware, crowds are likely at this spot when it’s good, so get there early.

Rusty, signing off.
