The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the coming weeks.
The surf window starts off pretty quiet. The first few days are a bit of a write-off with messy, onshore winds and poor quality waves. Honestly, you’re better off waiting for the real action.
It all kicks off properly on Tuesday, July 21st. That morning, Boneyards is looking prime. We’ve got a solid 8ft swell rolling in from the SSW, with a very long period of 14 seconds. That’s proper groundswell, bringing heaps of energy. The wind is glassy, dead calm – 0 mph. That’s about as clean as it gets. This is a powerful reef break, so it’s one for the experienced crew. The water temp is sitting at 60°, which is pretty much normal for this time of year.
The standout, without a doubt, is Thursday, July 23rd in the afternoon. Boneyards is going to be firing. We’re looking at a massive 12ft swell from the SW, with a monster 16-second period. The combined energy reading is massive – that’s serious power. The wind is glassy from the ENE. This is exceptional, but it’s big. Over 8ft, this is expert territory only. If you’re not absolutely on your game, sit this one out on the sand.
Friday, July 24th is still solid. The morning has 12ft swell from the SW with a 14-second period and glassy SE winds. Another incredible session for the experienced. The afternoon drops a touch to 10ft, but still clean with cross-off winds.
The following week has some fun waves, but nothing that matches the size and quality of that big Thursday. Monday, July 28th has a clean 8ft SW swell with a 14-second period and fresh offshore winds. A good session, but a step down from the peak.
After that, things taper off. By the end of July and into the start of August, the swell drops right out, with poor conditions and tiny waves. There’s a dry spell from the 31st until the 3rd of August.
Monday, August 3rd brings a little pulse back, with a 3ft to 4ft SW swell and 13-second period, and clean cross-off winds. It’s a marginal day, but the only game in town for the start of the new month.
The big winner here is that Thursday the 23rd. Mark it in your calendar, but only if you’ve got the skills for it.
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.
