The Lowdown
Right, mate, Rusty here. Let's have a proper look at what's on the table for the next couple of weeks.
We’ve only got one spot in the mix, and it’s a bit of a special one: Boneyards (reef). This place is an inconsistent beast, so when it lines up, it’s a proper event. The water temp is about average for this time of year, nothing wild there.
The short-term is a write-off, honestly. Saturday the 8th starts with a lumpy 10ft and a messy cross-on wind. It’s a no-go. The afternoon cleans up a bit with a cross-off wind, but the swell jumps to 13ft, which is proper big and only for the experienced crew. Sunday the 9th and Monday the 10th are still blown out by strong winds, even if the swell is a bit smaller. The wind is just too nasty.
We finally get a window on Tuesday the 11th. The morning is clean with a moderate offshore wind, dropping to 6ft, then the afternoon gets even better with a gentle offshore and 4ft. This is a nice, mellow session for a Tuesday, but the wave energy is only moderate (952 in the morning, 794 in the afternoon).
The real standout starts to build on Wednesday the 12th. The morning has 6ft, but the afternoon is where it gets exciting – 7ft, a gentle offshore wind, and a very long period of 18 seconds. This is a groundswell, and at a reef setup like Boneyards, that’s going to produce some beautifully shaped, powerful lines. The energy is strong (2467). Thursday the 13th is the absolute pick of the first week. The morning is 8ft with an 18-second period and gentle offshore winds – that’s a dream combination (energy at 4138). The afternoon holds at 8ft with a 17-second period. This is proper, expert-level surf.
Friday the 14th is still solid, with 6ft and glassy conditions in the afternoon – a real treat for the experienced surfer, but it's a bit smaller. Saturday the 15th is a total mess again, with a fresh cross-on wind ruining the 6ft swell. Not worth it.
The second week has a few promising blips. Sunday the 16th is a beast, with a clean 10ft and light winds (energy at 3309+). Monday the 17th morning is glassy with 8ft, but the wind goes wrong in the afternoon. The middle of the week (Tuesday 19th, Wednesday 20th) is mostly blown out or messy. The best of the whole 16-day window is Saturday the 22nd. It’s a long way off, but the forecast is for a massive 16ft swell with a fresh offshore wind. The combined energy is enormous (7603 in the morning, 9375 in the afternoon). That’s a colossal day for the experts only, and it’s a long-range call, so keep an eye on it. Sunday the 23rd finishes up with a glassy 8ft, which is a solid consolation.
Best on offer: The standout is Thursday the 13th, with that 8ft, 18-second groundswell and gentle offshore winds. Just pure, powerful reef perfection for those who can handle it. The long-range Saturday the 22nd is the other massive one, but it’s a promise that could change.
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.
