Kugenuma Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cooking for Kugenuma Rivermouth over the next couple of weeks. First thing I gotta tell you – it’s a slow start. The first several days are pretty much a write-off for any proper surf, so don’t bother paddling out just yet.

The water temps are sitting at about 83°F, which feels a touch warmer than normal for this time of year. That’s a nice little bonus if you’re in the water, but you’ll be waiting a while for the waves to catch up.

From Tuesday the 1st right through to the 7th, it’s mostly tiny dribble – knee-high at best, with weak energy readings mostly under 100. Winds are all over the place, but even when it’s clean and glassy on the morning of the 2nd, there’s just nothing to ride. This stretch is a real flat spell, so save your energy.

Now, things start to perk up around the 8th. Tuesday the 8th brings a bit more size, with waves around 3ft to 5ft from the SSE. The wind is strong offshore from the north, which keeps things clean, but the energy is ramping up (303 to 639). Still, it’s more of a challenge than a treat – hard to paddle into when it’s that fresh out of the north.

The real standout window lands on Wednesday the 9th and Thursday the 10th. Wednesday afternoon we’re looking at solid 8ft swell from the SSE, with a long 14-second period. That’s proper groundswell energy, rating at 2064 – serious oomph. Wind is light and cross-off from the north, so it’ll be clean. This is for experienced surfers only – over 8ft is expert territory, and Thursday morning gets even bigger at 10ft (energy of 3354). That’s a big, powerful swell. The break is a rivermouth, so that long period swell should set up nicely. Crowds are likely here, but on days like these, it’ll be worth jostling for a wave.

After that spike, it gets a bit messy again. The 11th and 12th are blown out with onshore winds and choppy conditions. Don’t bother. There’s a small rebound on the 13th and 14th with clean offshore winds, but wave heights drop back under 3ft – more of a longboard roll than a proper session.

Looking further ahead, the 15th and 16th show another pulse of size. Tuesday the 15th morning has 8ft from the SSE again, but onshore winds spoil it. The real gem might be the morning of Wednesday the 16th – 8ft from the S, glassy conditions (light air, no wind). That’s a long way out, so take it with a grain of salt, but if it holds, it’ll be a beauty. Energy reads at 1280 – strong and clean.

So, if you’re an experienced surfer, circle Wednesday the 9th and Thursday the 10th as the best on offer. For the brave and skilled, Wednesday the 16th morning is a promising long-range call.

Rusty.
