Table - best surf conditions forecast for Boneyards over the next 16 days.
Alright, let’s break it down. We’ve got a 16-day run here, and it’s a slow start. The real heaters are stacked late in the window, so don’t get discouraged by the early days.
The first rideable swell hits on Sunday, July 12th at Boneyards. It’s a reef break, open to the west, and we’re looking at a clean 4ft SSW groundswell, with a period of 11 seconds. The wind is a gentle offshore from the ESE, keeping it clean. The combined swell energy is moderate (548). It’s surfable, but not the best of the window.
Monday, July 13th is smaller, dropping to 3ft with the same SSW direction, but the wind goes glassy in the morning – a real treat for the conditions. The energy drops to a weak 171. It’s a very ordinary day, but the glassy surface makes it worth a paddle.
Now, things get interesting from Wednesday, July 15th. A big SW groundswell starts to fill in, but the wind is onshore or cross-on, making it a bit of a challenge. The swell hits 5ft on Wednesday morning (energy 1360), and then jumps to a solid 10ft by the afternoon (energy 4161). That’s strong wave energy. This is getting into expert territory, but the wind is not ideal for Boneyards.
Thursday, July 16th stays big, with 10ft SW swell (energy 2722) in the morning, but it’s still onshore. The wind does improve on Friday, July 17th with a fresh 18 mph offshore from the SE, but the swell is 8ft (energy 1585). That’s a clean, powerful wave for experienced surfers, but the wind is fresh.
The real standout of the whole forecast is Thursday, July 23rd. Boneyards is looking at a 10ft SW groundswell (15-second period) with glassy, perfect conditions. The combined swell energy is very strong (3874). This is a classic, heavy reef break with a long period, so it will be pitching and hollow. It’s for experts only. The crowds are listed as “sometimes,” so you might have some company, but with waves this good, it’s worth it.
After that, the wind turns nasty on the 24th, with strong cross-on breezes making a mess of the 10ft swell. The 25th and 26th are a write-off with near-gale force winds and poor conditions. The window closes on Monday, July 27th with a return to glassy conditions and a 6ft SW swell (energy 1548), offering a clean, fun day for those who stuck it out.
Overall, the best bet is the 23rd of July. It’s a big, clean, glassy day at Boneyards. The 22nd is also a solid option with moderate offshore winds and 6ft to 6ft swell. The beginning of the week is small but clean, and the middle is big but messy. Keep your wetsuit on, it’s gonna be a wild ride.

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.
