The Lowdown

Alright, Rusty here, let's have a look at what's on the table for the next couple of weeks.

First off, it's a bit of a slow start. We're looking at Tuesday the 4th and Wednesday the 5th, and honestly, it's not worth paddling out for the slop we've got. The swell is there, but the conditions are just average at best. The only real interest starts to build later on.

The standout of the whole forecast is definitely Friday the 7th at Canunda National Park (reef). We’re looking at a solid 10ft wave from the WSW on the morning, with a long 15-second period – that's proper groundswell energy. And the wind? Glassy offshore from the NNE. The water temp is sitting pretty normal for the time of year at 58°, so no surprises there. The combined wave energy is pumping hard (5825) – that’s moderate to strong stuff. This is going to be clean, powerful, and for experienced surfers only. The afternoon holds a 7ft swell with an even longer 17-second period, still with offshore breezes. If you're an experienced surfer, this is your window. The crowds are listed as "sometimes," so you might get a few out there, but it won't be a zoo.

Saturday the 8th keeps the fun going with 10ft early, but the wind is a fresh 19 mph offshore from the north. It'll be clean but a bit muscular. The wave energy is still strong (4471). As the day goes on, the wind picks up to 22 mph, making it a bit more of a mission.

After that, the swell gets huge. From Monday the 10th right through to the end of the week, we’re talking 16ft to 26ft waves. That’s massive, heavy, and for experts only. The problem is the wind. It swings around to strong cross-shore and cross-off directions with near gale-force gusts. The wave energy numbers are insane (32848 on Monday morning) but it will be a mess – lumpy, choppy, and blown out. For a reef break, that’s not your friend. It might look more fun for a kite surfer than a paddle surfer on those days.

The second week calms down a bit. Saturday 15th offers a 10ft to 12ft SW swell with clean cross-off winds, but the wave energy is lower (4275). It’s a marginal call. A real promising window pops up on Tuesday 18th morning: 10ft SW swell with a 16-second period and glassy offshore winds from the NNE. The wave energy is moderate (4978) and it's clean. That looks like a great session for experienced folks.

So bottom line: if you're an experienced surfer, Friday the 7th is the absolute pick of the bunch with the best mix of size, quality, and clean wind. Keep an eye on Tuesday the 18th as a solid, promising option. The rest is either too big, too windy, or just marginal.

Rusty.

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 Canunda National Park 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.
