The Lowdown
Alright folks, Rusty here. Let’s get into it. The next couple of weeks are a real mixed bag at Inamura Point, with a quiet, frustrating start before a couple of sessions that have me genuinely excited, especially for the experienced crew.
Right off the bat, we’ve got a long gap of nothing worthwhile. From now through to the morning of Sunday the 8th, it’s basically a write-off. The swell is tiny – we’re talking knee-high dribble at 1.0ft – and the wave energy is sad, sitting at just 29 (29). You’d be fighting an onshore breeze or strong winds for nothing. The morning of the 8th shows a jump in energy to 270 (270) with a 3ft SSE swell and clean offshore wind from the NNE, but it’s called marginal. It’s better, but not worth a special trip.
Now, let’s talk about the standout window. The real action kicks off on Wednesday the 9th. That morning, the ocean wakes up proper. We get a 7ft SE groundswell rumbling in with a long 14 second period. The wave energy is pumping hard at 1577 (1577). It’s got that cross-off wind from the East, keeping it clean. At 7ft, this is for advanced surfers only. That long period swell will wrap into Inamura Point nicely, holding its shape.
But the absolute gem, the best on offer, is the morning of Thursday the 10th. I’m getting a bit emotional just thinking about it. Glassy conditions – zero wind – and a solid 8ft S swell with a 14 second period. The energy is a massive 2578 (2578). It’s going to be flawless, powerful, and clean. This is big, strong groundswell. The size means it’s strictly for experienced surfers. The water temp is about average for this time of year.
After that peak, the swell stays solid through the 11th with a 10ft SSE swell, but the winds get more tricky. The following days into the second week are largely blown out by strong onshore southerly winds, with the swell dropping back down, making for messy conditions that just don’t offer the same quality.
So, to sum it up: the first week is a total bust. The absolute standouts are the morning of the 9th and especially the glassy morning of the 10th. If you’re advanced and can wait, those are your sessions.
Rusty.

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.
