The Lowdown

Alright, Rusty here. Let’s walk through Boneyards for the next two weeks or so. This reef doesn’t fire all the time, so we gotta pick our moments.

Water temp is about 58°, which is a tad colder than usual – nothing wild, but a 4/3 is a good call.

We kick off Thursday, August 20th with a proper swell. Thursday morning is the best of the lot. You’re looking at a solid 12ft SW swell, period around 13 seconds, and the combined energy is huge at 3903 – that’s serious power. Wind is a clean cross-off from the SSE at 9 mph. This is for experienced surfers only; it’s big and punchy. Thursday afternoon is a bit smaller at 10ft, still solid.

Friday, August 21st morning is another good one. Swell drops to 7ft from the SW, but the wind goes pure offshore from the SE at 16 mph. Energy is 947, and the waves will be clean and steep.

The weekend gets mixed. Saturday, August 22nd has cross-on winds and a mix of small, average swell. Sunday, August 23rd morning brings back 7ft from the WSW with a longer 13-second period and cross-off wind – energy at 1908. That’s a decent session. Monday, August 24th is still surfable but wind picks up to 19 mph in the afternoon.

Tuesday, August 25th is another sweet spot. Morning has 8ft SW swell with a long 14-second period and fresh offshore SE wind at 19 mph. Combined energy is 2373 – that’s a solid, powerful groundswell. The waves will be clean and lined up. Tuesday afternoon is similar but a touch smaller.

Wednesday, August 26th is light cross-on wind from the NNW, swell down to 5ft. Okay but nothing special.

Thursday, August 27th morning is calm with light offshore SE wind but only 4ft of swell. The afternoon stretches out with a 15-second period, which will wrap nicely into the reef even at 4ft.

Friday, August 28th has a solid 8ft WSW swell with that long 15-second period, energy at 2930. But the cross-on wind from the NNW will rough it up a bit. Still, for strong paddlers, there are big walls. Saturday, August 29th is similar size with cleaner cross-off wind.

Things fade from Sunday, August 30th. By Monday, August 31st, it’s under 2ft and looking poor.

Then a big spike shows up for Tuesday, September 1st: a huge 10ft to 12ft SW groundswell, 15-second period, energy over 5000. But the cross-on wind from the NNW at 9 mph will make it lumpy. Experts only. Wednesday, September 2nd is blown out with near gale winds.

The very last day, Friday, September 4th, has a tiny 4ft WSW swell with glassy conditions – calm and clean, but it’s a long way off.

The top pick is Thursday, August 20th morning. Big, clean, powerful. Second is Tuesday, August 25th morning with the strong offshore wind. The big September 1st swell is promising but risky with the wind.

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.
