The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way.
Alright, let's be straight with each other. The next couple of weeks are a bit of a mixed bag, with a lot of wind to work through. The water temperature at Boneyards is currently sitting at 57°F, which is a bit colder than normal for this time of year. That's a pretty noticeable chill, so you'll want the thick rubber.
Looking ahead, the first real opportunity to get a wave doesn’t really show up until Wednesday morning, September 16th. We've got a solid 10ft swell coming from the southwest, but the wind is howling from the southeast at 25 mph, making it a cross-offshore breeze. The surface will be clean, but the wave energy is strong (3816). That kind of size is for the experienced crew only. The afternoon drops to a more manageable 7ft, but the wind stays strong.
Thursday, September 17th, is more of the same. Clean conditions with a 8ft SW swell in the morning and 6ft in the afternoon, but that wind is still pumping at 28 mph, making it a real battle to get out. This is borderline kite-surfing territory.
The next standout window, and probably the best of the whole forecast, is Monday morning, September 21st. The wind finally drops to a moderate 16 mph offshore from the southeast, creating clean lines. The swell is a bit smaller at 4ft from the WSW with a solid 12-second period, offering good shape. The wave energy is moderate (551). This is the one to circle on your calendar. The crowds can sometimes be a thing at Boneyards, but on a Monday morning with a moderate swell, you might get a few waves to yourself. Tuesday morning, September 22nd, is another beauty. Light offshore wind, gentle at 9 mph, with a 4ft SSW swell and a 13-second period. The energy is a touch higher (830). This is as good as it gets for the next two weeks. Thursday, September 24th, also looks promising with moderate offshore wind and 5ft SW swell.
After that, things get a bit wind-affected again through the weekend and into the start of October. There's a small window on Monday, September 28th, with a fresh offshore breeze and a long-period 3ft SW swell (16 seconds), which could be clean but small. The following Tuesday sees light rain and onshore wind, so that’s a write-off.
Overall, keep your eyes on the 21st and 22nd of September. That's your best chance for a proper session.
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.
