The Lowdown
Alright folks, Rusty here, and I’ve been staring at the charts for our local patch. It’s a bit of a mixed bag coming our way, so let’s get into it.
We’re looking at a solid stretch of days ahead, but the start is a little rough. The swell is showing some serious size early on, but the wind has got it all messy. For Monday the 10th, we’ve got an 8ft SW groundswell (12-second period) pushing in, but that 12 mph south wind is making things choppy. The wave energy is pumping at 1944 (moderate to strong), but it’s not clean enough to get excited about. The afternoon actually gets bigger at 10ft, but the wind swings more onshore and it’s just poor.
Tuesday the 11th is a write-off. Even with a decent 8ft SSW groundswell, the onshore wind is too strong and the conditions are just poor.
Wednesday the 12th is where we start seeing a glimmer. The morning is small at 3ft, but that 21-second period is *very* long period groundswell. The problem is the wind is a fresh cross-onshore, making it lumpy. The afternoon jumps to 10ft from the east, but the period is short (8 seconds) and it’s messy. Not for surfing.
Thursday the 13th and Friday the 14th stay marginal. The swell is back to a nice SW direction with long periods (16-17 seconds) and moderate energy (2760-2927), but the wind is cross-onshore and light to moderate, keeping a chop on the surface. The water temp feels about average for this time of year, so the rubber’s fine.
Now, Saturday the 15th is the first standout. The morning has a clean 4ft SW swell (14-second period) with a light cross-offshore wind. The energy is a more relaxed 806, but the waves will be clean. Then the afternoon? Glassy. Zero wind. The same 4ft SW swell will be absolute perfection. This is the pick of the first week for sure.
Sunday the 16th keeps the clean theme going with a morning offshore wind and the same 4ft SW swell. The following Monday the 17th morning is also looking clean with a 3ft SW groundswell (16 seconds) and barely any wind.
We hit a small lull mid-week, with Tuesday the 18th and Wednesday the 19th morning seeing a drop in quality. But Wednesday morning the 19th is another glassy session, with a 5ft SW swell and 13-second period. That’s going to be a special one for the experienced crew.
Thursday the 20th brings a shift. The morning is a clean 6ft ESE short-period swell (8 seconds) – not ideal. But the afternoon is a standout: an 8ft E swell with a 9-second period and clean offshore wind. This is punchy, hollow, and for experts only.
Things get a bit weaker into the end of the week. But then, looking further out to Sunday the 23rd and Monday the 24th, we see a serious pulse of energy. The afternoon of the 23rd has a 13ft SSW groundswell with a 15-second period and massive energy (7114). Monday morning the 24th still has 10ft with 4441 energy. These are huge, powerful swells, but the wind is onshore and it’s just going to be a dangerous, blown-out mess. Only for the most experienced and foolish.
So, the real standout is Saturday afternoon, the 15th, with glassy conditions on a clean 4ft SW swell. The second best is Wednesday morning the 19th, with glassy 5ft SW swell. Get on 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.
