The Lowdown
Right, let’s have a look at Inamura Point. This is a reef setup that likes a south swell, and it’s an advanced wave. Over the next couple of weeks, we’re staring down the barrel of a very slow start – a proper dry spell – before a little pulse of energy shows up later.
The entire first week is pretty much a write-off. From Sunday the 6th right through to the weekend of the 12th and 13th, the swell is tiny or non-existent to start, then when it does bump up a bit on Monday the 7th, it’s a messy, blown-out stormy mess with strong onshore winds and a combined energy of 649 (moderate) jumping to 1124 (strong) by the afternoon. That’s not surfable, just a washing machine. Tuesday the 8th morning has a little bit of life with 5ft from the south, but it’s a cross-off wind and a score that’s just not worth getting excited about. The rest of that week is a dribble of knee-high slop.
There is a notable gap of about five days with no real recommendations. Nothing worth paddling out for.
The one and only real standout in this whole 16-day window is Wednesday the 9th of September. The morning starts with a clean 4ft south-southwest swell, period around 10 seconds, and a light offshore wind from the north-northeast. The combined energy sits at 363 (moderate). The afternoon holds up even better – 5ft from the south, period of 9 seconds, and a gentle offshore wind from the north. That’s clean, lined-up reef waves. It’s the best on offer, and it’s a definite window for the advanced crew. Thursday the 10th is still surfable through the morning with 3ft from the south and a moderate offshore blowing, but it’s not as good. After that, it fades fast.
Water temperature is about average for the time of year, nothing wild.
After the 9th and 10th, we drop right back to flatness and tiny windswell until the very end of the run. On Sunday the 20th of September, there’s a late pulse of 6ft from the south-southwest, short period of 6 seconds, with a cross-shore wind. Combined energy of 257 (moderate). It’s a messy, bumpy option, more of a grovel than a proper session. For the rest of it, the energy is really weak – single-digit values – and the wind is all over the shop.
So, if you’re keen, circle Wednesday the 9th. That’s the session. The rest is a waiting game.

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.
