The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s comin’ our way.

We’ve got a decent run of swell ahead but it’s gonna be a mixed bag with the wind. The first couple of days are blown out, so we’re waiting for a real gem to shine. The standout window is Saturday morning the 15th – that’s your best bet. After that, there are more windows of clean conditions, especially if you’re experienced and can handle some size.

Thursday 13th is pretty average. We’ve got a solid 8ft SW groundswell rollin’ in (moderate-to-strong energy at 3782) but the cross wind from the NNE is messin’ it up, givin’ us a bit of chop. The afternoon eases to 7ft but gets cross-onshore. Not ideal.

Friday 14th is no good. Winds pick up hard out of the NNW, cross-onshore, and the swell drops to 6ft and 6ft. Choppy and messy all day. Stay on the sand.

Now, Saturday 15th – this is the one, mate. The morning glass-off is magic. Southerly breeze at only 3 mph, the water is glassy, and we’ve got a clean 6ft WSW groundswell with a period of 14 seconds and solid energy (1335). The water temp is 57°F, which is a bit colder than normal for this time of year – that’s about 3° cooler, so expect a little extra chill in the air and water. Afternoon cleans up with a light S breeze, cross-off, and the swell bumps to 7ft. For the experienced crew, this is your best session of the whole outlook. Boneyards is an exposed reef break, inconsistent, but when it lines up… magic. Crowds can show up sometimes, so get in early.

Sunday 16th through Monday 17th – the wind shifts back to northerly and cross-onshore, with some solid 8ft and 7ft WSW swell, but the quality’s just not there. Choppy or light ripples.

Tuesday 18th stays marginal, wind onshore and cross, swell around 5-6ft.

Wednesday 19th and Thursday 20th – better wind direction with SSE breezes and even a touch of offshore at 22 mph on Thursday morning, but the swell is on the smaller side, 6ft, and the energy’s droppin’ (down to 846). Clean, but not a standout.

Friday 21st morning we get another glass-off! Northerly breeze at just 3 mph, 6ft SW groundswell, glassy conditions, and expect very good surf. A solid second-best window here.

Saturday 22nd – a bigger, cleaner pulse. Morning brings 8ft SW groundswell (very strong energy at 2930) with a 14-second period and clean cross-off southerly breeze. This will be a good one for experienced surfers, though by afternoon it’s a touch less organised. Still clean.

Sunday 23rd morning – offshore SE breeze at 16 mph, 7ft WSW swell, clean and punchy. Another strong day for the experienced crew.

Monday 24th – morning offshore ESE breeze at 9 mph, 5ft WSW swell, clean. A nice, more manageable day for intermediates.

From Tuesday 25th into Wednesday 26th the swell hangs in at 4-6ft, clean but unremarkable.

Then Thursday 27th and Friday 28th – a late pulse of serious size. We’re talkin’ 10ft building to 12ft SW swell (very strong energy, 4104 to 5525), with a 14-15 second period and clean cross-off SSE winds. This is proper big groundswell. The 15-second period means it’ll be a long-period groundswell – works best at a reef like Boneyards, but it’s gonna be a heavy, powerful wave only for experts. Not for the faint-hearted.

Overall, the best on offer is Saturday 15th (morning glass) and the late pulse on Thursday 27th and Friday 28th for the brave. There’s a gap of a few poor days here and there, but the surf keeps comin’.

This is Rusty, signin’ off.

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.
