The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for Boneyards.

Overall, we’ve got a bit of a mixed bag over the next couple of weeks. The first several days are a bit of a write-off, with messy onshores and marginal conditions. But there are a couple of clear windows where it’ll really turn on, especially for the crew who don’t mind a bit of size. The standout days are Saturday the 22nd and Monday the 17th, and those are the ones to circle on the calendar.

Right now, on Thursday the 13th, the water temp is sitting at 57°, which is a solid 3° colder than usual for this time of year. You’re gonna want a thick wetsuit – it’s properly chilly out there.

Thursday morning offers a 8ft SW swell. The period is a very long 17 seconds – proper groundswell, lots of energy, with a combined energy reading of 3782. Wind is a cross-shore from the NNE at 9 mph, so it’s a bit chopped up and the report calls it marginal. By afternoon, the swell drops to 7ft and the wind swings cross-onshore, making it choppy. Not worth paddling out.

Friday the 14th is a no-go. Onshore wind is howling at 16 mph in the morning, dropping to 9 mph in the afternoon, but still cross-onshore. Swell is around 6-6ft, but it’s messy. Score is a zero. Save your energy.

Saturday the 15th looks better. Morning sees a 6ft WSW swell with an offshore wind from the SE at just 3 mph. It’s clean. The combined energy is 1299. Afternoon holds 7ft with a light 6 mph cross-offshore wind, still clean. It’s described as excellent for experienced surfers. This is a decent option if you’re keen, but it’s not the absolute best of the run.

Sunday the 16th is back to onshore slop. Cross-on wind all day, choppy. Swell around 6-7ft, but with the wind ruining it. Skip it.

Now, Monday the 17th… this is a gem. The morning is glassy. Absolutely no wind, zero mph, from the ESE. The swell is 8ft from the WSW with a 13-second period. Combined energy is 2354. The report says it’s excellent for experienced surfers. This is a true standout – glassy conditions with a good size swell from a solid direction. It’ll be clean and powerful. Afternoon stays clean with a light cross-offshore breeze. This is the pick of the first week for a surfer who can handle some juice.

Tuesday the 18th drops off. Cross-on wind picks back up, swell drops to 6-6ft, and it’s only marginal. Wednesday the 19th has some gnarly wind – 25 mph from the SE. Even though it’s offshore, it’ll be a battle to get out. Swell is smallish at 5-6ft.

Thursday the 20th and Friday the 21st are blown out by near-gale to fresh offshore winds. Swell is small, around 4-5ft. Hard work for little reward. Not recommended.

The real standout is Saturday the 22nd. Morning brings a 7ft SW swell with a very long 16-second period, combined energy of 3032. The wind is offshore from the SE at 12 mph. The report calls it excellent for experienced surfers. That’s a big, clean groundswell with proper power. Afternoon sees the swell jump to 10ft – that’s big, only for experts – with strong offshore wind at 25 mph. It’ll be clean but a serious paddle. If you’re experienced, the morning session on the 22nd is the one to aim for.

Sunday the 23rd is still solid with offshore winds and a 6-7ft SW swell, but the wind is a bit stronger. Good, but not the top pick.

Monday the 24th has cleaner, smaller conditions – 4-4ft with light offshore winds. Nice for a smaller board, but not a standout.

From Tuesday the 25th onward, it's a dry spell. Cross-onshore winds kick in, swell drops below 3ft, and the conditions turn poor. That run looks to last through to at least the 28th.

So, to wrap it: Saturday the 22nd is the big, powerful, clean standout for the experienced crew. Monday the 17th is your next best bet with glassy conditions. Saturday the 15th is a decent backup if you need a fix. The rest is mostly a write-off until we see what the next forecast brings.

Stay stoked,
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.
