The Lowdown
G’day, I’m Rusty, and I’ve been staring at this stretch of coast for a long time. Let’s get real about what’s on the table for the next 16 days at Inamura Point. I’ll be straight with you – it’s a pretty grim outlook for any kind of decent paddle surfing. The first proper surf worth mentioning doesn’t show up until Monday the 7th of September, but it’s a raw, messy beast.
The overall pattern is one of very little quality. We’ve got a solid pulse of swell arriving Monday morning, with wave heights around 7 ft pushing from the south, but the wind is onshore and strong from the south at 22 mph. That’s a recipe for lumpy, blown-out conditions. The combined energy of all swells directed here is moderate to strong at 710, but with a fresh southerly wind, it’s going to be a struggle. By Monday afternoon, the swell is up to 7 ft, energy jumps to 1330 (strong to very strong), but the wind swings to SSW at 19 mph and goes cross-onshore, making it a lumpy, expert-only affair. The period is 9 seconds, so it’s a short-period wind swell, not the clean groundswell we’d hope for.
Tuesday the 8th of September sees the swell drop to 3 ft from the SSW in the morning, but the wind is still cross-onshore from the SSW at 12 mph, making for choppy, poor surf. The afternoon offers a slight glimmer: the wind turns offshore from the north at 9 mph, and the swell shifts to SSE at 3 ft with a period of 9 seconds. The combined energy is 237 (moderate), and the conditions are described as “good surf conditions.” That afternoon window is the best of a very ordinary bunch – clean, offshore wind, but the swell is small. It’s a true standout in this otherwise bleak run.
From Wednesday the 9th onward, things fall apart. The swell bounces between 1.0 ft and 6 ft, but the wind is generally cross-onshore, cross-offshore, or too light, and the combined energy rarely breaks 100 after the 10th. The period is short, often 7 to 9 seconds, and the water temperature is around 83°F, which is a touch warmer than normal for this time of year – about 3°F above average, so it’s notable but not extreme.
The gap after the Tuesday afternoon window is brutal. From Wednesday the 9th all the way through to Monday the 21st of September, there’s virtually nothing rideable. The swell is tiny, the energy is weak (single-digit and low double-digit figures), and the conditions are consistently poor. The only slight exception is Sunday the 13th of September, when there’s a 1 ft swell from the SSW with a longer period of 12 seconds in the morning, and 11 seconds in the afternoon, but the combined energy is only 51 and 64, respectively – weak. It’s described as “surfable waves but very ordinary conditions,” but with a cross-offshore wind, it’s clean but tiny. Not worth getting excited about.
Bottom line: if you’re a paddler, Tuesday afternoon the 8th of September is the only real option. The wind is offshore from the north, the swell is 3 ft from the SSE, and it’s clean. For the rest of the window, it’s a write-off. The setup is more interesting for kite surfing than paddle surfing on the bigger days with strong wind and lumpy conditions. The crowds at Inamura Point can be often, but on a day like this, you’ll likely have the place to yourself.
Rusty out.

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.
