The Lowdown
Alright crew, Rusty here. Let’s get into what Boneyards has cooked up for the next couple of weeks. It’s a slow start, but there’s some heavy stuff on the horizon if you’ve got the patience.
The water’s sitting at about 58° – that’s about 2° colder than average for this time of year at Boneyards (reef). You’ll want a solid 5/4. The first few days are a complete bust. Friday the 4th and Saturday the 5th are lost to gale-force and near-gale offshore winds that make paddling out feel like a war. Just stay home.
Sunday the 6th is where things get interesting. The morning brings a clean 8ft swell from the SW with a very long 18-second period and some serious energy (3471). That’s proper groundswell. The wind is a moderate offshore breeze from the ESE – clean and rideable. This is for the experienced crew only; it’s got some weight. The afternoon holds at 7ft (16-sec period) with that same clean offshore flow. This is your first real standout.
Monday the 7th and Tuesday the 8th drop back into marginal stuff with light cross-onshore breezes messing up the face. The swell drops below 7ft and the energy fades. Wednesday and Thursday the 9th-10th are a mixed bag – some clean moments with moderate cross-offshore winds, but not really worth the drive.
Saturday the 12th is the big one. This is the standout of the entire outlook. We’re looking at a solid 12ft SW swell with a very long 17-second period. The energy reading is massive at 6549. The morning is clean, with a light ESE offshore breeze – glassy conditions for the reef. This is exceptional, expert-level surf. The afternoon stays clean with an 12ft SW swell (16-sec) and near-glassy conditions. This is the day to clear your schedule.
From the 13th through the 16th, it’s a rough patch. Onshore winds and lumpy conditions ruin what would have been solid 7-10ft SW swell. The 16th is interesting – a 12ft SW swell with an 18-second period and a massive energy reading of 8710, but the wind is a moderate cross-shore chop. It’s messy for paddling, but the raw power is there. This one looks more interesting for kite surfing than paddle surfing.
The final standout comes on Thursday the 17th. The afternoon session delivers a massive 15ft WSW swell with a 14-second period and an incredible energy reading of 13654. The wind is a strong cross-offshore breeze, keeping it clean. This is big, powerful, and only for the fearless. Friday the 18th backs it up with a cleaner 10ft SW swell (12-sec) and moderate offshore winds, offering excellent surf for experienced surfers.
The last couple of days, the 19th, are a washout with strong onshore winds and messy conditions.
Overall, lock in Sunday the 6th and absolutely circle Saturday the 12th and Thursday the 17th. The gaps in between are long and quiet, so pick your moments. The water’s cold, the swell is real, and Boneyards is ready to rumble.
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.
