The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a solid 16-day window ahead, but it’s not a straight line. There’s a bit of a wait for the really good stuff, but when it fires, it’s going to be worth it.

The first call is for Tuesday the 21st of July. Boneyards is the only spot on the radar, and it’s a reef break that’s known to be a bit inconsistent. We’ve got a solid 8ft to 10ft SW groundswell rolling in, with a period of 13 to 14 seconds. That’s some serious energy moving through (2765 to 2816 in the combined energy reading). The real kicker is the wind. Tuesday morning is glassy, absolutely dead calm, and the afternoon goes clean with a light cross-off breeze. This is for experienced surfers only – that swell size is pushing into heavy territory. Water temp is running at 60°F, which is pretty much bang on average for this time of year, so not a wetsuit drama.

Wednesday the 22nd takes a step back. The wind switches onshore and picks up, and the quality drops right off. The swell is still there, but the conditions are messy. That’s a day to sit out.

The standout session of the whole outlook is hands down Thursday the 24th of July. The morning is pure magic. We’re looking at an 12ft SW swell with a 15-second period – that’s proper long-period groundswell (5737 combined energy). The wind is glassy. For a reef like Boneyards, this is the kind of day that gets the blood pumping. It’s big, it’s clean, and it’s only for experts. If you’ve got the skills, this is the one to circle. The afternoon is still big but the wind picks up a little.

Friday the 25th and Saturday the 26th keep the quality high with offshore winds. The swell drops a bit to the 7ft to 8ft range, but it’s still clean and fun for experienced surfers. The crowd factor at Boneyards is listed as “sometimes” busy, so on a run like this, expect a few others in the line-up.

After the 26th, things get tricky. Sunday the 27th sees the wind howling, and by Monday the 28th we’ve got gale-force offshore winds. The swell is huge, 12ft, but the wind is so strong it’s going to be a battle to even get out. The combined energy is through the roof (5489 to 5506), but it’s a fight, not a surf. This setup looks more interesting for kite surfing than paddle surfing.

The window from the 29th of July to the 1st of August brings a return to form. We’ve got a solid 8ft to 10ft SW swell with clean conditions. The morning of the 31st of July is a real highlight in this second week – 10ft SW swell, 15-second period, and a gentle offshore breeze (4724 combined energy). That’s a powerful, clean day for a reef.

The 1st of August is a nice little glassy session, with 7ft to 7ft swell. That’s a bit more manageable and still clean.

The very end of the run, from the 2nd of August onwards, fades out. The wind turns onshore and the swell drops off. The energy readings fall to the low hundreds, nothing to get excited about. By the 4th and 5th of August, there’s a tiny pulse of 5ft to 7ft WSW swell, but it’s a long way out and the consistency is questionable. A promising sign, but nothing to bank on.

So, the best of the best: lock in the morning of Thursday the 24th of July and the morning of Friday the 31st of July. That’s your swell window.

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.
