The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next stretch.

We’ve got a bit of a slow start, but once the swell kicks in, it’s gonna be a ripper of a run for anyone who knows what they’re doing. The early part of the week is a write-off – Monday the 20th is flat and messy, so save your energy. The real action kicks off Tuesday morning, the 21st of July, and it just builds from there.

The standout window is from Thursday the 24th through to early August. The peak of the party looks like Friday the 31st of July and Saturday the 1st of August, but that’s a fair way out, so keep an eye on it. The water temp is sitting around 60°, which is pretty much normal for this time of year, so no surprises there.

Let’s get into the details.

Boneyards (a reef setup) is the only game in town, and it’s a ripper when it fires. It’s inconsistent and only for intermediate to expert crew – if you’re a beginner, stay well clear when it’s over 8ft. This spot loves a solid SW groundswell, and we’ve got plenty of that.

Tuesday morning the 21st of July sees a solid 8ft SW groundswell with a long 14-second period, and the wind is glassy from the SSE. That’s a dream start for experienced surfers. The combined energy is pumping at 2764 (moderate to strong). By Tuesday afternoon, it’s a touch bigger at 10ft, still SW, with a clean cross-off breeze. You’ll want to be out there.

Wednesday the 22nd is a bit of a mixed bag – morning has onshore wind, but the afternoon picks up a cross-off from the east with a clean 7ft SW swell. Not the best, but still fun.

Thursday the 23rd morning is a write-off with strong onshore winds, but don’t write it off. Thursday afternoon turns it on again: 8ft SW, 13-second period, and a light cross-off breeze from the east. The energy is massive at 3254 (strong). Then Friday the 24th morning is the real gem – 13ft of SW groundswell with a 15-second period, offshore wind from the east, clean as a whistle, and exceptional conditions for experts. Combined energy is 5889 (very strong). That’s a bucket-list session.

Saturday the 25th still holds: 7ft SW with a moderate offshore breeze in the morning, clean. The afternoon drops a touch but still solid.

We get a bit of a lull through Sunday the 26th and Monday the 27th, but there’s still rideable swell in the 7ft range, especially with clean winds on Sunday afternoon.

Now, the big one – Friday the 31st of July. The morning shows a massive 15ft SW groundswell with a 16-second period, light onshore wind, but the energy is off the charts at 10113 (very strong). The afternoon bumps to 16ft SW. This is huge, expert-only territory. The wind is light cross-onshore, so it might be a bit lumpy, but the power is unreal.

Saturday the 1st of August keeps it going with 15ft SSW groundswell and a clean cross-off breeze in the morning. Combined energy is 6002 (very strong). Another day for the big dogs.

After that, it drops off fast. By Sunday the 2nd of August, we’re down to 2ft and weak energy (95), and it’s pretty much over from there. Monday the 3rd and Tuesday the 4th are poor with onshore winds and small, messy swell.

The best of the best? Friday the 24th of July morning is the true standout: 13ft SW, 15-second period, offshore breeze, clean as glass. Second best is Friday the 31st of July morning for raw power, but it’s a long-range call so don’t book your flights just yet. Crowds are possible at Boneyards when it’s good, so get there early.

Stay safe, and don’t paddle out if you’re not ready for the size.

Rusty.

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.
