The Lowdown
Alright, let’s break it down.
For the next 16 days, we’ve got some waves coming, but a lot of it is going to be blown out by strong wind. You have to be smart about when you paddle out.
The spot to watch is Boneyards. It’s a reef break, exposed to the west swell. It’s inconsistent, so you gotta be ready when it turns on. The water is freezing cold right now—about 55°F—which is a solid 5°F colder than usual for this time of year. That’s a big anomaly, so suit up properly.
We start off on Monday, September 7th with a 7ft SW swell at 13 seconds, but the wind is light cross-shore, so it’s not clean. The wave energy is moderate at 1339.
Tuesday, September 8th morning is your first decent window. Swell drops to 3ft from the WSW, but the wind goes cross-off and light. It’s clean. Energy is lower at 585, but the conditions will be good. The afternoon is smaller at 2ft.
Thursday, September 10th brings a jump to 8ft SW swell with a 15-second period, but a moderate breeze keeps it from being perfect. Energy is strong at 2662. The report says marginal.
Friday, September 11th and Saturday, September 12th are a write-off. You’re looking at near-gale winds up to 34 mph. The swell is still there—6ft to 8ft—but the ocean will be a mess and very hard to paddle out.
The highlight of the first week is Sunday, September 13th. Offshore wind, moderate breeze. You’ve got a solid 7ft SW swell in the morning and 6ft in the afternoon, both with 13-14 second periods. Energy is in the 1285 to 1754 range. The report says excellent for experienced surfers. This is your day.
The middle of the week goes sour again. Monday, September 14th through Tuesday, September 15th has strong cross-onshore wind ruining things. The 15th afternoon has a 5ft swell with a super long 22-second period, but the strong cross-on wind will make it a lumpy mess. Energy is 2349, but it’s not rideable.
The second week gets big. Wednesday, September 16th sees a massive 15ft WSW swell with a 16-second period. The combined energy is huge at 11280. The wind is onshore on the morning and cross-shore on the afternoon. This is expert-only, and even then, it’s going to be a struggle.
Thursday, September 17th stays huge with 15ft to 10ft swells and strong, clean cross-off wind. Energy is 9345. Big-wave territory only.
The period settles down toward the end. Saturday, September 19th morning is clean with a 4ft SW swell and practically glassy conditions. Energy is low at 505, but it’ll be fun and clean.
Sunday, September 20th brings back 7ft WSW swells with moderate wind.
The real standout of the second week, if you can handle the size, is Tuesday, September 22nd morning. You have an 12ft WSW swell, moderate offshore wind, and combined energy of 3858. The report says excellent for experienced surfers. That’s your big-wave target.
Final call: Get on Sunday, September 13th for the best clean session. If you want big, powerful waves, aim for Tuesday, September 22nd. Everything in between is either blown out or just too big for most.

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.
