The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for Inamura Point over the next couple of weeks.

To be straight with you, the next week and a half is pretty grim. We’ve got a long stretch of small, weak surf with lousy conditions. The water temp is sitting at 81°F, which is pretty normal for this time of year. From Wednesday the 2nd right through to the 8th, it’s mostly onshore or cross-onshore wind, tiny waves, and poor surf. The exception is Friday the 4th morning – you get a little 2ft S swell with a 10-second period and a light cross-offshore breeze, so the lines will look clean, but it’s still very ordinary. The combined energy is weak (86), so don’t expect much push.

Saturday the 5th and Sunday the 6th see fresh offshore winds but the swell is tiny – 1ft to 2ft – and the energy is barely there (56 to 28). Hard to get excited. Monday the 7th is even worse with strong offshore wind that makes paddling into anything a real battle.

Then on Tuesday the 8th, we get a jump in swell to 4ft from the south, with a 9-second period, but unfortunately the wind swings cross-offshore and it stays messy. Energy picks up a bit (266), but it’s still a pass.

The real standout window starts on Wednesday the 9th. The swell jumps big – 12ft from the south, 12-second period (long-period groundswell). Now, this is serious size: 12ft is expert territory. The combined energy is strong (3871). The wind is cross-on, so the surf will be a bit choppy, but there’s a lot of water moving. For a reef break like Inamura Point, that long-period groundswell from the south should wrap in nicely, but it’ll be heavy. This is for experienced crew only.

Thursday the 10th shapes up as the best day of the whole outlook. In the morning, we’ve got 6ft south swell, 10-second period, with a light cross-offshore breeze. The energy is solid (821). Then Thursday afternoon it gets even better – the wind goes glassy, dead calm, with 4ft south swell. The water will be like glass. That’s the one to circle. Still a decent-sized wave, not ridiculous, and clean conditions. It’ll be a very good session if you can get out.

After that, from Friday the 11th through to the 15th, it all drops off again. Tiny waves, mostly under 2ft, and the wind is either offshore or cross-off, but there’s just not enough swell to ride. The energy is weak (mostly under 60). There’s a little spike on Tuesday the 15th afternoon with a 2ft swell from south at a very long 19-second period (that’s a proper groundswell), but the wind is onshore and the energy is only moderate (197) – the period is too long for this beach to break properly with such a small wave.

The final days, Wednesday the 16th and Thursday the 17th, see another size increase – 6ft to 7ft south swell – but the wind is onshore and it’s messy. Thursday the 17th morning has 7ft south swell, 12-second period, with light onshore wind – could be okay for experts, but the wind direction is against it.

Best on offer: Without doubt, Thursday the 10th. The morning has 6ft south swell with a nice 10-second period and a light offshore wind. The afternoon goes glassy with 4ft south swell – that’s the gold. Second best is the big swell on Wednesday the 9th, but that’s only for the brave with the cross-on wind.

Overall, a tough start, a promising middle, and a fading end. Keep an eye on that Thursday the 10th.

Rusty.

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.
