The Lowdown
Alright, let’s break it down.
Over the next 16 days at Boneyards, it’s a real rollercoaster. Water temp’s sitting at 14°, which is a bit colder than usual for this time of year—nothing extreme, but you’ll feel it after a long session.
We start Monday the 24th with 2ft of SSW swell at 10 seconds and a cross-off breeze. Wave energy is solid (1196), but it’s a marginal session—nothing to write home about.
Tuesday the 25th gets bigger—swell climbing to 8ft in the morning and staying around 7ft in the afternoon, coming from SW and WSW with periods up to 14 seconds. But the wind is screaming from the SE at 22 to 28 mph. It’s cross-off, so not totally blown out, but it’s a messy, tough paddle. Wave energy hits (2549), but the quality isn’t there.
Wednesday the 26th is the pick of the first week. Morning has 5ft of WSW swell at 13 seconds, with offshore wind from the ESE at 16 mph. Cleaner, more lined up. The afternoon improves further: 4ft swell, period dropping to 12 seconds, lighter offshore wind at 12 mph. Wave energy is still strong (1075), and conditions are clean and fun for experienced surfers.
Thursday the 27th through the weekend turns poor—onshore winds, weak swell, bumpy conditions. Sunday the 30th sees swell jump back to 8ft, but onshore winds ruin it. That’s expert-only size, but with the wind, it’s a no-go.
From the 1st of September, things get raw. Swell hits 11-12ft on Tuesday and Wednesday, but wind is cross-on or cross-off at gale force. Wave energy peaks at (5089). This is kite-surf territory, not paddle surfing.
Here’s the highlight: Saturday the 5th and Sunday the 6th of September. Saturday morning delivers 8ft of south swell at 10 seconds, with a fresh offshore breeze from the ESE at 19 mph. Clean, hollow, rippable. Wave energy (1426). Sunday the 6th is even better: same 8ft swell, but lighter offshore wind at just 9 mph. Near glassy in the morning, gentle offshore, and that reef will be firing. That’s the session. Monday the 7th also looks sweet with a smaller 4ft swell but a long 16-second period from the SW—clean, groomed waves.
Second week is promising but less certain. Lock in Sunday the 6th of September: solid south swell (8ft), light offshore wind, and a reef that lines up perfectly. Crowds are possible—"sometimes"—so get down early.

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.
