The Lowdown

Alright, mate, Rusty again. Let’s break it down for the imperial crew.

We’re looking at a slow start today, but there’s solid swell coming. The first proper session is Friday the 28th of August.

Thursday the 27th is a dud. Choppy cross-on wind and weak energy (788) – not worth the effort.

Friday the 28th gets things moving. Morning at Boneyards is clean with offshore wind and a 4ft S swell, but the real highlight is Friday afternoon. Light SSE cross-off breeze, the swell rolls in from the WSW at 4ft, and the period is a long 14 seconds. Energy is moderate (783), and it’s glassy. That’s the pick for the early part.

Saturday the 29th morning is a cracker. Swell is around 5ft from the WSW, period a very long 15 seconds, with a gentle offshore wind. Energy is moderate (1038). This is excellent for the experienced crew – clean, lined-up groundswell. Saturday afternoon sees the swell push to nearly 8ft, but the wind jumps to 30 km/h from the S, so it’s clean but getting heavy. Energy is strong (3090). Sunday the 30th stays in the 8ft range with similar wind and strong energy, but quality is a bit off.

Monday the 31st is smaller, around 7ft, but onshore wind ruins it.

Then there’s a big dry spell. Tuesday the 1st of September through Friday the 5th are messy or dangerous. The 1st has strong onshore winds and poor conditions. Wednesday the 2nd is insane – 21ft swell with a 17-second period, energy at 24941. That’s way too big, experts only and risky. Thursday and Friday are blown out by gale-force offshore winds that make paddling out a mission, even as the swell drops.

After that rough patch, things clean up. Sunday the 6th of September morning is a treat. Clean conditions, a 4ft WSW swell with a very long 17-second period, and light wind. Energy is moderate (890). The reef handles that long period beautifully. Monday the 7th and Tuesday the 8th keep the run going with similar 4ft to 5ft swells, clean and user-friendly. Solid days.

Around the 11th of September, the swell jumps back up to 10ft, but the period drops to 10 seconds and the wind is light cross-on. Not perfect, but big.

Best sessions: Friday the 28th afternoon for the glassy start, and Saturday the 29th morning for the offshore perfection. The early second-week run from the 6th to the 8th of September is also a beauty – clean, consistent, and mellow.

Crowds can show up at Boneyards sometimes, so dawn patrol is your friend.

Water temp is 59°F, a bit colder than average for the season, so bring a steamer.

Stay wet,
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.
