The Lowdown
Right then, let’s have a look at what’s on the cards for Inamura Point. It’s a bit of a frustrating start, to be honest. For the first week, the waves are tiny and the conditions aren't really giving us much to work with. There's a long stretch of poor surf right through to the start of September, with the swell barely lifting a paddle. It’s going to be a real test of patience.
The first few days, from the 29th of August through to the 1st of September, we’re looking at ankle to knee-high junk, around 0.7ft to 1.3ft. The wind is mostly offshore or cross-off, which is clean, but there’s just no energy in the water. The combined energy is really weak, sitting between 18 and 42 units. Not worth getting wet for.
Things stay flat and poor right through the 2nd and into the 3rd of September, though on the 3rd we see a slight bump to 2.0ft from the SSW with a period of 11 seconds, and the energy ticks up to 123 units – still very weak, but it’s a hint of something. The wind is onshore and choppy though, so it’s a no-go.
Finally, on the morning of Friday the 4th of September, we get a pulse of 6.6ft swell from the south. That’s a proper increase, but it’s short-period windswell at 7 seconds. The wind is light cross-off from the NE, so the surface might look clean, but the waves will be lumpy and weak. It’s a marginal call at best. The afternoon turns into a mess with cross-onshore wind. The 5th and 6th drop back into the tiny stuff with strong offshore winds that just make paddling a chore.
Now, the real standout moment in this whole outlook is Monday the 7th of September. The morning session has got my attention. We’ve got a solid 3.9ft swell from the south, with a long period of 12 seconds, and the wind is dead glassy – zero, nothing, a mirror. The combined energy is a solid moderate 525 units. That’s going to offer up clean, lined-up waves with real push. It’s a reef break, so that long-period swell will wrap in beautifully and hold its shape. This is about as good as it gets for the whole forecast.
The 8th of September brings some serious size – 11.5ft – but it’s onshore and lumpy, so that’s for the crazies only, and the quality is poor. The 9th has some clean 8.2ft surf with a 12-second period, but it’s still got that “marginal” tag on it, likely due to the tide or shape. That’s a good option for the more experienced crew on a bigger board.
After that, the swell settles down again, with small to moderate surf through to the 11th. The 10th has a nice morning of 3.9ft from the south with a moderate offshore breeze – very surfable.
Then, the final mention for the period is Sunday the 13th of September. That morning is another potential gem. The swell bumps up to 7.9ft from the SSE, but with a very long period of 14 seconds. The water is glassy, no wind. That kind of energy, 2064 units, is strong and will punch through. At that size, it’s not a beginner wave, but for anyone who knows what they’re doing at Inamura Point, it’s going to be a special few hours. The afternoon gets a bit onshore and messy.
So, to wrap it up: the first week is a write-off. Don’t bother. Mark your calendar for the morning of Monday, the 7th of September for the best combination of clean glass and proper swell. The morning of Sunday, the 13th of September is the other big swinger, but that’s for the confident crew. The water temp is about 82.4°, which is a touch warmer than normal for this time of year.
Stay patient, lads. The waiting game pays off.

Information about the Inamura Point Surf forecast
The above surf forecast table for Inamura Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Inamura Point can be found by selecting the local surf guide option on the grey menu. Our Inamura Point surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Inamura Point) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Inamura Point may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
