The Lowdown
Alright, Rusty here again, breaking down the same Boneyards forecast but in feet and Fahrenheit.
The water temp is sitting at 58°, which is a bit colder than the long-term average for this time of year, so you’ll want that extra rubber.
The start of the period is a dud. Wednesday afternoon has 8ft of SW swell, but it’s getting hammered by a 25 mph cross-on breeze. The energy is strong, but it’s a mess. Skip it.
Thursday morning and Friday morning are where it gets real. The swell jumps to 12ft. Friday morning is the clear standout early on. The wind is light at 6 mph offshore from the ENE, with a period of 14 seconds. The combined energy is massive. That’s excellent for the experienced crew. 12ft on a reef is not for beginners, and crowds are possible.
The weekend turns ugly. Saturday is cross-on, and then Sunday and Monday get wrecked by a 31-34 mph near gale pushing 13ft swell. The energy is pumping over 7000, but that’s kite-surfing territory, not paddle surfing.
The second week starts to clean up. Tuesday morning has 6ft SS swell with a 20 mph offshore, but it’s a bit fresh. Wednesday morning is the standout for the second week: 6ft SW swell, 9 mph offshore breeze, and a period of 18 seconds. That’s very long-period groundswell, and the energy reading is in the moderate range. It’s clean and glassy. A reef is the right place for that long-period stuff.
Thursday morning is also a gem, with 6ft SW swell and a 3 mph offshore. Smooth as glass.
After that, it’s a run of smaller, 4 to 5ft WSW swell with cross-on breezes. It’s average, but nothing to get excited about.
Monday the 18th of August pops up again with a clean 12ft SW swell and a light offshore. That’s another big window for the experts, but it’s a long way out.
Best bets: the morning of Friday the 7th for the big, clean swell, and the morning of Wednesday the 12th for the smaller, glassy session. The first is a lock for the experienced, the second is a cleaner, more manageable option for the week after.
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.
