The Lowdown
Alright, I'm Rusty, and I've been eyeballing the charts for Boneyards. It's a reef break, exposed to the west swell, and it's shaping up to be a classic run of conditions for the experienced crew. The water temp is running a bit colder than normal for this time of year at 57.6°, so don't be shy with the rubber.
Right now, we're looking at a solid window of surf coming up. The first call is on Monday the 10th, but it's honestly just a teaser. You've got a clean 4.3ft offshore wind, but the energy's only moderate (918) and the period is short. It's surfable for the keen, but not the standout.
The real juice starts flowing from Wednesday the 12th. That morning, we see a proper groundswell pulse, with a long period of 18 seconds and 6.2ft of clean, lined-up swell. The wind is light and offshore. This is excellent, experienced-only territory with moderate wave energy (2538). Wednesday afternoon holds similar quality, with 6.6ft swell and glassy conditions. This is the sort of day where you paddle out and feel the ocean is in a generous mood.
Thursday the 13th has an 8.2ft morning, but a cross-shore wind makes it a bit of a battle, though still worthwhile for the diehards. The afternoon, however, is a moment of pure magic. The wind goes completely glassy, and the swell is still a meaty 7.5ft. That combination is as good as it gets for a reef like this.
Friday the 14th is another beauty, with a glassy 6.2ft in the afternoon and solid energy. Saturday is smaller and a bit bumpy. Sunday the 16th is messy, but the following week brings back the big stuff.
The absolute standout, the one I'd circle on the calendar, is Monday the 17th. We're looking at 9.8ft of clean, groundswell with a moderate offshore wind. The wave energy is very strong (4204). This is big-wave territory, experts only. If you've got the skills and the quiver, that's your session. The same size and quality roll into Wednesday the 19th as well.
There's also a promising long-range call for the 23rd, with another big 11.5ft pulse and strong offshore wind, but that's a week and a half out, so keep an eye on it.
Overall, this is a run of consistently solid, clean swell for the experienced surfer. The crowds at Boneyards can show up when it's good, but that's the price you pay for a wave this good. The reef handles the long-period groundswell beautifully, so the shape should be top-shelf. You won't need to worry about it being too straight here.
For the newer surfers, be aware that any day with swell over 4.9ft, especially the 6.2ft-plus days, is going to be too much. The 8.2ft to 9.8ft days are strictly for the experts. It's a reef, after all.
So, the takeaway: grab your step-up, check the tides, and be ready for some world-class waves at Boneyards. The ocean is about to deliver.

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.
