The Lowdown
Alright, mate, Rusty here. Let's talk about what we’ve got coming down the pipeline for Inamura Point. This is a reef setup that needs a decent southerly direction to work its magic, and we've got a long wait ahead.
The next 16 days start off pretty flat and messy. There’s nothing worth paddling out for until at least the 19th of September. For over a week, we're looking at tiny, weak swell with poor conditions—cross-offshore breezes and clean faces on the 16th and 17th, but with swell barely reaching 2ft, it’s just not worth the effort. The water is a touch warmer than average for this time of year, sitting at 81°.
The real story begins to develop around the 19th of September. We get a pulse of solid groundswell from the southeast, with wave heights around 5ft to 5ft and a period of 14 seconds. The combined energy is massive—over 1100—and it’s showing as moderate wave energy. The wind is a fresh offshore from the north, which will keep things clean for the advanced crew. This swell is solid enough that it’s probably too much for beginners, but for the experienced surfer, it’s got potential.
The standout session looks to be on the 20th of September, Sunday afternoon. Swell from the SSE at 6ft, with a long 13-second period, producing strong wave energy (1361). With that strong offshore breeze, the waves should be well-shaped and powerful. Expect it to be a bit of a challenge to paddle into, but the reward will be there for those who can handle it. Remember, this spot is fairly consistent, but it can get crowded when the waves are on.
The following week sees a major pulse of southerly energy around the 22nd of September, with wave heights hitting a massive 21ft and combined energy over 14000. That’s very strong wave energy. However, the wind is from the ESE, creating choppy and messy conditions. This setup looks far more interesting for kite surfing than paddle surfing, so I’d give that a miss. By the 27th of September, we get a clean, glassy morning with 3ft swell from the SE and a solid 12-second period, offering some clean, fun waves for a brief moment.
In summary, if you’re an advanced surfer, your best bet is the 20th of September at Inamura Point. It’s not a guaranteed classic, but with the right tide and a bit of luck, it could be a good session. Keep an eye on the charts, as long-range calls are always a bit less certain.
Rusty.

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.
