The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming our way for Inamura Point over the next couple of weeks. Gotta be straight with you from the start: the next week or so is a write-off for any sort of decent paddle. It’s going to be a long, quiet stretch. From now right through until about the 23rd of August, we’re looking at tiny, weak waves and mostly onshore or cross-onshore wind. The odd morning might have a clean-ish look to it with light cross-off breezes from the ENE, but the swell is just paltry, coming in at 0.7ft to 1ft most days, with combined energy barely hitting 29 (weak). There’s nothing worth wetsuiting up for. You'd be better off finding something else to do. This break is a proper reef setup for advanced surfers, and it just isn't showing any love right now.
For the morning of Monday the 24th, things finally start to look interesting. We've got a building SSE groundswell coming in at 3ft with a very long period of 16 seconds. The combined energy jumps to 500 (moderate). The wind is a light offshore from the NNE, promising clean conditions. That said, this is a long-period groundswell, which can make reefs and points really come alive, but it also means longer waits between sets. Still, this is the first real glimmer of quality.
Now, the standout period is the middle of next week, and it's worth keeping an eye on. The morning of Tuesday the 25th of August looks solid: a 5ft SSE swell, with a period of 15 seconds and a combined energy of 1084 (strong). Winds are light and cross-off from the ENE, so it should be clean up there. It’s solid enough to push into the “expert” zone for this reef. That’s a serious window for the confident crew.
But if you had to pick one absolute winner from this whole forecast, it’s got to be the morning of Wednesday the 26th of August. This is about as good as it gets for Inamura Point. A 6ft S swell, 15-second period, combined energy of 1362 (strong), and the wind goes glassy. Dead calm. Offshore? No. Onshore? No. It’s glass. That’s a rare gift. The wave direction (S) is right in the optimum zone for this break, so expect those reef lines to be holding up and peeling beautifully. This is a high-performance morning for experts. The water temp is about average for this time of year, so no nasty surprises there. Even if the afternoons get messy with a southerly breeze, that morning session is a gem.
After that, the surf stays big for the rest of the period, but it gets increasingly tricky. Thursday the 27th, Friday the 28th, and Saturday the 29th see head-high to overhead-plus S swell (7ft to 8ft) with plenty of energy, but the wind swings onshore and gets howling, especially on that Saturday with a gale-force southerly at 43 mph. That’s kite-surfing territory, not surfing. It’s going to be messy and blown out. The swell is too big for beginners anyway.
Then, late in the run, we get another clean-up. The mornings of Sunday the 30th and Monday the 31st of August deliver a nice 4ft to 5ft SE groundswell with a 16-second period, and crucially, light cross-off winds from the NE. Combined energy is in the thousands (strong). That’s a more manageable size with clean conditions, and the SE direction is still a solid match for this spot. It’s a promising close to the month.
Into the start of September, the models are showing a massive spike - 25ft on Tuesday the 1st of September - but that is way, way too big for Inamura Point. That’s a no-go for anyone but the most extreme chargers with a death wish, and honestly, it’s probably too big for the break to handle. Keep an eye on it, but don’t plan around it.
So to sum it up: the first week is dead. The real action is that glassy morning on Wednesday the 26th of August – that’s your best bet. The mornings of the 25th and the 30th/31st are also solid, clean options.
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.
