The Lowdown
Alright, folks, Rusty here. Let’s break down what Boneyards is cooking up.
We’ve got a slow start to the period. Monday the 7th is a total dud with a messy cross-on breeze and poor conditions. Tuesday the 8th morning is a cruel joke – glassy calm winds but the swell is barely 3ft from the WSW. It’s clean as a whistle but lacks any punch. The water temp is a biting 55°F, which is a whopping 5°F colder than normal. You’ll want your thickest wetsuit, no question.
The first real highlight hits Thursday the 10th morning. We’re looking at an 8ft swell from the WSW with a very long 15-second period. The power is massive at (3326). This is a proper groundswell, and with a cross-off breeze from the SSE, it’ll be clean. On a reef like Boneyards, that long-period energy will produce some solid, lined-up waves. But at 8ft, this is for experts only. If you’re not seasoned in heavy surf, sit this one out.
Friday the 11th is a total bust for paddling. The offshore wind is howling at 28-31 mph, hitting “near gale” force. It’s nearly impossible to get out and paddle. Honestly, with that wind and the swell running, this looks more interesting for kite surfing than a standard surf session.
After a rough, windy weekend, we get a massive pulse on Wednesday the 16th. The morning shows a gigantic 15ft swell from the WSW, pulsing at a 16-second period. The energy reading is off the charts at (9514). This is a monster, a clean but extremely dangerous day for elite-level surfers only. The afternoon drops slightly to 12ft, but it’s still a full-on, heavy session.
The last real standout is Sunday the 20th in the morning. You get a solid 8ft swell from the WSW with a long 14-second period, and the wind is a clean cross-off from the SSE. The energy is strong at (2033). This is a much friendlier size than the big day on the 16th, offering excellent surf for experienced surfers. It’s still a big day, but one you can actually paddle into.
Beyond that, the wind picks up and stays onshore, blowing out most of the remaining swell. The second week is mostly a write-off after that Sunday morning session.
Keep an eye on the chill and pick your days wisely. This is Rusty, signing off.

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.

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.
