The Lowdown
Alright, Rusty here, let's break down what's cookin' at Boneyards.
First up, water temps are sittin' right around 59°, which is pretty much what you'd expect for this time of year. No surprises there.
The next couple of days are a bit of a write-off, to be honest. Tuesday afternoon's got a big 7ft swell on the way, but that 28 mph cross-off wind is gonna be a handful, and the energy is absolutely cranking (2048), but it's just not gonna be clean. We're looking at Thursday and Friday for a bit of a reset, with some smaller, cleaner lines but nothing that'll get the heart racing.
Now, Wednesday morning on the 26th is where it starts to get interesting. That's a solid 4ft, 13-second period groundswell from the WSW, and the wind is offshore from the ESE at 12 mph. That's clean, lined-up surf with a solid 1149 energy reading. Perfect for someone with a bit of experience. The afternoon holds the same size with a lighter wind, making it glassy. That's a standout session.
Things get a bit wonky again Thursday with a shift in wind, but Friday morning on the 28th looks decent with a clean 4ft swell from the S and light winds. The energy is moderate (642). It's a solid option.
Now, if you've got the patience, the real gem is shaping up for Sunday the 30th. The morning is looking like the pick of the forecast. You've got a 8ft swell from the WSW, with a 13-second period and a 1990 energy reading. The wind is cross-off from the SSE at a gentle 9 mph. That means big, powerful, and clean waves. This is for the experienced crew only, as it's gonna be a handful. The afternoon holds similar size but a bit stronger wind, but still clean.
The following week is a mixed bag. Monday the 31st is a bit meh, and then Tuesday the 1st of September is a big, messy no-go. That 16ft swell with 16 mph onshore winds (8509 energy) is a beast for the kiters, not for paddle-surfing. Wednesday the 2nd cleans up with a big 13ft Southwest swell and cross-off winds, but it's still a mission for the brave. The 3rd of September Thursday morning is a standout: 10ft, 12-second swell, glassy, and clean. That's a proper session for the big-wave chargers.
After that, the swell drops right off into the second week with a few small, clean mornings, but nothing to write home about. The 6th of September has a tiny 3ft long-period groundswell from the SSW (16 seconds), which is a bit of a tease, but it's clean. The 8th and 9th are small and not great.
So, the real standout sessions are Wednesday morning the 26th for a clean, fun 4ft wave, and Sunday morning the 30th for the bigger, more powerful 8ft swell. Thursday morning the 3rd of September is the one for the big-wave crew, with glassy 10ft surf. Boneyards is an inconsistent reef, so when it's on, it's special.
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.
