Kugenuma Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a run of waves coming through for Kugenuma Rivermouth, but it’s a bit of a mixed bag. The water’s sitting at 75°, which is about a degree and a half colder than usual for this time of year – nothing too crazy, just a little nip in the air.

The first couple of days are looking marginal. Thursday afternoon kicks off with a 5ft swell from the SSE, but the wind is onshore at 12 mph, making it a bit bumpy. The wave energy is moderate though (1088). Friday morning sees a jump to 6ft from the S, with a long 15 second period, and lighter 9 mph onshore wind. The energy is building (1410), but it’s still got that onshore wind slop. Friday afternoon gets worse – 7ft from the south but the wind picks up to 16 mph, and the energy is strong (2105), yet the conditions are poor. Saturday morning is the best of this early run: 7ft from the SSW, 16 second period, and only 9 mph onshore wind. That’s a lot of water moving (2368), but the wind is still on it. Saturday afternoon, the wind bumps up to 19 mph, so it’s not worth it.

Now, Sunday is more of the same, with a morning of 6ft SSW swell and 9 mph onshore wind (1661), but the afternoon turns cross-onshore and choppy. Honestly, for the first four days, the wind is just not playing ball. The swell is there, but it’s messy.

The standout window is Monday, 13 July. That’s the one. Morning and afternoon both go glassy – wind drops to 3 mph. The swell drops to 3ft from the SSW, with a 13 second period, so the energy is low (222), but it’ll be clean and fun for a bigger board. The wind is glassy, so expect silky smooth faces. The river mouth setup will actually work well here with that light wind. It’s not a day for big waves, but it’s a day for perfect lines.

After that, Tuesday drops off quickly. 2ft and 1ft, with cross-offshore winds, but it’s just too small. The energy plummets (102 and 62). From Wednesday 15 July through to the end of the 16-day window, it’s mostly tiny, onshore, and poor. There’s a tiny window Sunday 19 July with a 2ft SSW swell and cross-offshore wind (130), but it’s very ordinary. Monday 20 July morning goes glassy again with 2ft, but it’s barely a ripple.

So, to wrap it up: the first week is all about waiting for Monday 13 July. That’s your best bet. After that, it’s a long stretch of flatness and small, windy junk until the very end of the period. The river mouth will be the place for that Monday glass-off.

Rusty out.
