The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming our way for the next couple of weeks.
The outlook is a bit of a mixed bag. We’ve got a point break called Cowrie Beach on the radar. It’s an inconsistent wave, so you have to pick your moments. The swell energy is going to be all over the place, from a weak 479 to a massive 9703, so we’ll see some serious power at times.
The first few days are a write-off. Sunday the 6th has a bumpy 7ft SW swell at 14 seconds, but that cross-on wind is ruining it. The water temp is sitting at 57°F which is pretty normal for this time of year, so nothing weird there. Monday the 7th and Tuesday the 8th are also messy or just questionable. Wednesday the 9th and Thursday the 10th are a straight-up no-go; we’re looking at huge 12ft SW swell, but the wind is howling and the conditions are just poor. That’s a lot of energy (9703) going to waste. Friday the 11th and Saturday the 12th morning are still marginal.
Now, the first real standout is Saturday the 12th afternoon. The wind goes light offshore from the SE, which is a major positive. The swell still has some size at 6ft from the SW, but with a period of 15 seconds, it’s a proper groundswell. The combined energy is 1393, which is moderate. It’s going to be clean, and that’s when the wave will line up best. Crowds are possible here, so get in the water early.
Sunday the 13th and Monday the 14th are back to poor conditions. Tuesday the 15th sees another massive swell of 12ft, but it’s just too big for this break and the wind is messy. Keep an eye on the 17th of September. Thursday morning is looking clean with a cross-offshore breeze, and a 10ft SW swell. The period is only 9 seconds, so it’s a bit short period, but the conditions are excellent for experienced surfers. Thursday afternoon is even better, with a light breeze and a 8ft SW swell, also clean. That’s your second standout – a real window of quality.
The final days of the 18th and 19th fall apart again with strong winds, and the 20th and 21st are only marginal, though the 21st afternoon shows a glimmer of hope with clean conditions.
Stay on it, and don’t sleep on that Saturday afternoon session.

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