The Lowdown
Alright, let’s get into it. This is a classic Boneyards outlook, and it’s a bit of a mixed bag. The reef there needs a solid, clean swell to really fire, and we’ve got a few windows where the stars align. But there’s also a lot of wind and junk in the mix.
Overall, the pattern starts off pretty quiet and then builds into a proper swell window. There’s a gap of no good surf from the start of the period until the afternoon of the 15th. The first real chance is on Wednesday afternoon, July 15th, when a long-period groundswell starts to show. The swell is 10ft from the SW with a period of 15 seconds, which is a very long period, and the combined energy is strong (4806). That’s a lot of juice, but it’s a bit cross-shore with small wind ripples. It’s a heavy reef wave at that size, so really only for the experienced crew.
The standout of the whole run is Thursday morning, July 16th. The wind is dead calm, glassy conditions, and you’ve got 8ft of SW swell at 13 seconds. That’s clean, powerful, and the break (Boneyards) will be showing its best shape. The combined energy is moderate to strong (2494). It’s still a solid size, so it’s for intermediate to expert surfers only. Crowds are possible here, so you might have some company.
Another good one to circle is Sunday morning, July 19th. Glassy conditions again, with a 7ft WSW swell at 12 seconds. The water temperature is about 60°F, which is pretty normal for this time of year, so a spring suit is the call.
Looking further out, the second week has some serious size. Tuesday morning, July 21st, has a clean 10ft SSW swell at 16 seconds, with a light offshore wind, and the energy is very strong (4808). That’s a promising, but long-range, call. Then into the 23rd, Thursday morning, you’ve got a massive 13ft WSW swell at 14 seconds, with a cross-offshore wind and clean conditions. The energy is huge (8663). That’s for experts only, and the waves will be holding a lot of power. The 26th also has a clean 10ft WSW swell on Sunday morning with a light offshore.
The rest of the period is largely blown out, with strong winds and lumpy conditions, especially the 22nd, 24th, and 25th. The 25th afternoon has a 8ft SW swell with a very long 19 second period, but it’s cross-on and choppy, so it’s not going to be great.
So, bottom line: the best day to be in the water is Thursday, July 16th for the glassy, clean conditions. The Sunday the 19th is a close second. The later windows are promising but less certain, so keep an eye on the wind.

Information about the Boneyards Surf forecast
The above surf forecast table for Boneyards provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Boneyards can be found by selecting the local surf guide option on the grey menu. Our Boneyards 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 (Boneyards) 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 Boneyards 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.
