The Lowdown

Alright folks, Rusty here. Let’s have a good, hard look at what the ocean’s got cookin’ for us over the next couple of weeks.

To be brutally honest, this is a pretty flat and bleak stretch for Inamura Point. We’re looking at a run of small, unremarkable surf with very little to get excited about. There are a lot of days where it’s just not going to be worth paddling out unless you’re desperate for a splash. The good news is, it's not all completely dead – there are a couple of tiny windows where it might be just about rideable for the most die-hard souls among us.

The water temp is sitting at 81°, which is about normal for this time of year, so at least you won't need a thick suit.

The first bit of hope comes on Sunday morning, the 9th of August. We’ve got a small 2ft SSW swell rolling in with a 10-second period. The wave energy is a weak 151, and while it’s small, it’s glassy with an ESE breeze at 3 mph. It’s surfable, but it’s going to be super ordinary – think small, crumbly shoulders, not much push. The afternoon sees the wind swing onshore from the S, and it just gets messy. Not the one.

Monday the 10th is more of the same – small and weak. A 2ft S swell in the morning is clean with a cross-offshore NE wind, but it’s weak and there’s just not enough juice. We’re at the lower end of the energy scale here. This pattern of small, weak surf continues through Tuesday and Wednesday. There’s a moment on Wednesday afternoon, the 12th, with a light N offshore wind, but with wave heights at 2ft and weak energy, it's still just a knee-to-waist high dribble. The lack of size is the main problem.

From Thursday the 13th onward, it really goes downhill. The swell drops to 1ft and even 1ft with energy numbers dipping into the 20s and 30s. The winds are mostly cross-offshore or offshore, so it’ll look clean, but there’s just no wave to ride. It’s a classic case of all dress and nowhere to go. This flat spell looks set to run right through the middle of the month. We’re talking a solid week or more with essentially nothing on offer.

There is a slight uptick in the ocean’s pulse around the 22nd and 23rd of August. The swell edges back up to 2ft with a longer 10-11 second period, and the energy climbs back into the low 100s. But, and it’s a big but, the wind is looking onshore, which will chop it up and make it poor. Still, it’s the only sign of life we see in the extended forecast, though it’s over a week away, so don’t hold your breath. It’s promising, but about as uncertain as it gets.

So, here’s the bottom line: the next 16 days are a test of patience. There’s no standout swell, no big groundswell, no quality waves to chase. The only technically surfable days in the near term are Sunday the 9th and maybe Wednesday the 12th, but they are so small and weak that they’ll only be worth it for a longboard and low expectations. The light winds are a positive, but they can’t make up for the lack of swell.

This is one of those times where you might be better off doing some maintenance on your boards or going for a paddle. The ocean is having a rest, and we have to respect that. Forecasts can change, though, so keep an eye out. It tends not to stay this poor for long.

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.
