The Lowdown
Alright folks, Rusty here with a look at what's coming down the line for Outside Corner. We've got a solid stretch of persistent, clean south-west groundswell on the horizon, so let's get into it.
The pattern for the next couple of weeks is all about that constant, clean offshore flow. We're looking at consistent ESE to SE winds keeping the surf smooth for the majority of the run. The water's sitting at a warm 80°F which is pretty much bang on average for this time of year, so you can leave the thick rubber at home.
The opening weekend, Saturday 18th and Sunday 19th July, sees clean but less-than-ideal 4ft to 5ft of SW swell. The combined energy is moderate, sitting around the 900 to 980 mark, and with a period of 13 to 15 seconds there's some good shape on offer. The problem? The forecast is calling this marginal due to tide or some other factor, so don't expect perfection.
Monday 20th July is when things start to get interesting. The swell bumps up to 5ft on the morning and then jumps to a solid 7ft from the SSW by the afternoon. That energy value shoots right up to 2299, so there's some real grunt in the water. The period stretches to 16 seconds, meaning proper groundswell lines. This is definitely more of an advanced wave with that size, but it's clean with offshore winds, so the standouts on the 20th and into Tuesday 21st July look like the best of the first week. Be aware that crowds are sometimes a thing here, so you might have some company.
The swell dips a little mid-week, with Wednesday 22nd and Thursday 23rd dropping to around the 3ft mark, and the energy winding back down. It's still clean, but much smaller. The wind does pick up to 22 mph from the ESE on Friday 24th, but it remains offshore and clean.
Now, the real standout window looks like it might be at the tail end of the run, but it's a long way off so keep the salt in your hair. Around Friday 31st July, we see a significant pulse of SW swell. We're talking 6ft to 6ft with a period of 18 seconds, and the combined energy is a powerful 2753 to 2976. That's strong wave energy, and the direction matches the optimum SW direction for Outside Corner perfectly. This is a high-quality groundswell, but it's for experts only at that size. Saturday 1st August looks to keep that energy very strong at 2735 with a 5ft SW swell, but then the wind shifts and the swell goes a bit wonky with a shorter period SE component dropping in.
So, to boil it down: keep your eyes on Monday 20th and Tuesday 21st July for a solid, clean groundswell that's good for the advanced crew. For the long-range punt, Friday 31st July is the one that has the *potential* to be the cleanest, strongest swell of the whole period, but it’s a two-week forecast, so it's all promise at this stage. The rest of the time, it’s clean but generally small or not quite firing on all cylinders, with the forecast rating it as marginal.
Stay stoked, and I'll see you out there.

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 Outside Corner 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.
