The Lowdown
Alright, this is Rusty here, and I’ve been staring at the charts for the local zone. Let’s cut through the noise and talk swell.
First up, the water temp is sitting at about 83°, which is a touch warmer than normal for this time of year. Not a game-changer, but nice to know.
We’ve got a bit of a dry spell to get through. The first few days are pretty grim. Friday the 4th kicks off with some tiny 1.6ft S swell at Inamura Point, but it’s coming from the NE at 6 mph, which is cross-off, and the energy is weak (63). The conditions are just ordinary. Honestly, there’s nothing worth paddling out for on the 4th or 5th. The wind picks up strong on Saturday, and the swell drops further. Sunday the 6th is a write-off: strong offshore winds up to 28 mph but the swell is pitiful, around 0.7ft to 1.3ft. Clean, but impossible to surf.
The real action starts to build on Monday the 7th. A new S swell pushes in, hitting 5.9ft in the morning with a 10-second period and moderate wave energy (979). The wind is light and cross-shore from the W, so it’s a bit messy but rideable. The afternoon, however, gets a bit wild with a 9.8ft SSE swell, but it’s onshore and strong from the SSW at 19 mph, making it a total mess. That’s too big for beginners and the conditions are poor. Tuesday the 8th cleans up a bit with the swell holding around 5.2ft from the S, but the wind is cross-off from the NE, and the energy is moderate (693). It’s a possibility, but nothing special.
The standout is Wednesday the 9th, morning session. The swell drops slightly to 5.6ft from the S, period 10 seconds, and the energy is solid (569). But the key is the wind: it’s light offshore from the north at just 3 mph. That’s going to groom the face at Inamura Point beautifully. The rating says expect very good surf conditions. This is your window. The waves will be clean, with some punch, and the direction is straight out of the south, which is what this reef wants. It’s an advanced break, so this size is right in the sweet spot for skilled surfers. Crowds are possible, so get out early.
After that, we hit a long, slow fade. The swell drops below 3ft from the 10th onward, and the consistent onshore or cross-off winds keep things marginal. There’s a tiny pulse of glassy conditions on the 12th, but the swell is down to 1ft. Not worth it. The rest of the period through to the 19th is a desert of tiny, weak swells with poor energy readings (mostly under 40). The 16-day window ends with a tiny 2.3ft SSW swell on the 19th, but it’s onshore. No real hope in the second week.
So, if you’re itching for a wave, your only real shout is Wednesday morning, the 9th of September. Get on it.

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.
