The Lowdown
Alright, Rusty here, let's have a look at what's coming down the pipeline for the next couple of weeks.
First off, the water temp is sitting at 53.6°F, which is pretty much bang on average for this time of year, so no surprises there.
The week starts off slow with a bit of a wait. The first real chance to get wet comes on Thursday, the 6th, but honestly, it's pretty average. We're looking at a small 1.6ft swell from the WSW with a 13-second period, which is a nice long groundswell, but the energy is weak (118). The morning has a cross-off breeze, but it's just not enough push to get excited about. The afternoon goes flat and cross-shore, so I'd give that a miss.
Friday, the 7th, is where things start to get interesting. The swell picks up to 5.6ft from the NW in the morning, with that energy jumping to 610 (moderate). The wind is a clean cross-off from the East, and it stays offshore all day. By the afternoon, we've got a solid 7.2ft from the NW with a 10-second period, and the wind is straight offshore, making for some very clean, peeling lines. This is a standout for the early part of the window. The break is Cobden Breakwater and it's exposed to the WSW, so that NW swell is a good direction for it.
Saturday, the 8th, keeps the momentum with a 5.2ft swell from the NNW in the morning, dropping to 4.9ft in the afternoon. The wind stays offshore, so it'll be clean, but the period drops to 8 seconds, which is a bit short and less powerful. Still a good day for a session.
Now, Sunday, the 9th, is a big one. The morning brings a solid 9.8ft from the NNW with massive energy (1897), and the wind is a light cross-off. This is going to be pumping, but at 9.8ft, that's expert territory, big and powerful. The afternoon, however, gets stuffed. The swell jumps to 11.5ft from the W, but the wind swings cross-on, and the wave comment says it's too big for the break. So, the morning is the go, but only for the experienced crew.
We get a sweet little window on Monday, the 10th. The swell drops to a much more manageable 3.6ft from the WSW, but the period is a dreamy 15 seconds. The morning is offshore, and the afternoon goes flat calm, glassy. The energy is still moderate (601-602). This is a gem for a fun, clean session on a longboard or a mid-length.
Tuesday, the 11th, is small again at 1.6ft, but the period is a very long 19 seconds in the morning and 18 in the afternoon. The wind is offshore in the morning and glassy in the afternoon. It'll be clean, but only for the smallest of waves.
The middle of the week, Wednesday the 12th, has a morning of small 2.3ft surf with a long 16-second period, but the real action is the afternoon. The swell jumps to 6.2ft from the NW, the period is 12 seconds, and the energy is strong (1285). The wind is a light cross-off, making for excellent, clean conditions. That's another standout for the experienced surfers.
Thursday the 13th and Friday the 14th keep a solid 4.9ft to 7.9ft range going, with mostly clean, offshore winds, though the period on the 13th drops to 8 seconds. The 14th afternoon is a highlight with a 7.9ft NW swell, 11-second period, and a gentle offshore breeze.
Then we hit a wall. From Saturday the 15th through to Sunday the 16th, the swell goes huge. We're talking 14.8ft to 19.7ft, and every single period is flagged as "too big for this break." The energy readings are off the charts (9096 on the 15th afternoon). This is not for surfing, this is for watching. Maybe a kite surfer's dream, but not a paddle surfer's.
The following week, from Monday the 17th to Wednesday the 19th, the swell backs down to a more manageable 5.6ft to 8.2ft range, with good, clean conditions and cross-off winds. The 18th afternoon is a standout with a 5.6ft swell from the W, a 13-second period, and a light cross-off breeze. The 19th afternoon goes glassy.
Thursday the 20th offers a small 3.3ft morning, but the afternoon gets blown out with a 7.5ft swell and onshore wind.
And then, far out on the 21st of August, we see another massive swell pulse of 13.1ft from the W, and again, it's flagged as too big for the break. That's a long-range call, so keep an eye on it, but as it stands, it's a no-go.
So, the real standouts for the whole period are Friday the 7th afternoon for that clean, solid 7.2ft NW swell, and Monday the 10th for that glassy, long-period 3.6

Information about the Cobden Breakwater Surf forecast
The above surf forecast table for Cobden Breakwater provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cobden Breakwater can be found by selecting the local surf guide option on the grey menu. Our Cobden Breakwater 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 (Cobden Breakwater) 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 Cobden Breakwater 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.
