The Lowdown
Alright, Rusty here again. Let’s break this down in feet and degrees.
Water temp’s around 59°, pretty normal for the season. The big picture is a solid run of swell, but it takes a few days to dial in.
Wednesday 15 July – morning is a write-off at Boneyards. Cross-on wind, choppy, and the energy is big but messy. The afternoon is a different story. Light cross-off wind, a solid 10ft SW groundswell with a 16-second period. Powerful and heavy. This is for the experienced crew only.
Thursday 16 July – morning is glassy, absolute perfection. A clean 8ft SW swell at 13 seconds. This is your top session. The afternoon is still fun with a light cross breeze.
Friday 17 July – clean 7ft SW swell with offshore winds all day. Good shape, fun waves.
Saturday 18 July – morning is glassy but tiny, 3ft. Afternoon gets a 7ft onshore bump, but it’s messy.
Sunday 19 July through Monday 20 July – smaller, cleaner swells around 4ft to 6ft. Fun but not the highlight.
Tuesday 21 July – stay out. Massive 18ft SW swell with strong cross-on wind. Dangerous and blown out. Same for Wednesday 22 July with near gale winds.
The big standout – Thursday 23 July. The morning is exceptional. An 18ft SW groundswell with a 15-second period, and offshore wind from the SE. This is a monster, clean wave for experts only. The afternoon is still huge at 16ft. That morning window is the one.
Friday 24 July through Sunday 27 July – solid 7ft to 12ft SW swells with clean cross-off winds. Consistent and quality.
Boneyards is an inconsistent reef, so it lights up when it’s on. Expect crowds sometimes, especially on those big days. The week of the 28th keeps the swell going but the wind gets stronger, so it’s cleaner but still big.
Rusty out.

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.
