The Lowdown
Right then. I’m Rusty, and this is what I’m seeing for our little patch.
First up, don’t get your hopes up for most of the next two weeks. We’ve got a long, quiet stretch ahead, but there is one window that looks worth getting excited about. We’re talking about Coastguard Beach. That’s the only spot on the radar.
The water temperature is sitting at 68°, which is about 2° warmer than usual for this time of year, so it’s a touch on the mild side.
Let’s jump in. The first few days are a real write-off. Friday the 4th and Saturday the 5th are a total no-go with tiny, weak slop and rubbish wind. Sunday morning the 6th is still dead flat, but then things shift. Sunday afternoon the 6th is the standout of the whole outlook. We finally get a pulse of 4ft NE swell with an 8-second period and a combined wave energy of 201 (moderate energy). The wind is a light NNW cross-offshore breeze, so it’s going to be clean. This is your best chance for a surf. The swell is modest, so it’s fine for most levels, but the short period means it won’t have much push. Still, clean waves at that size are a good time.
Monday the 7th has a drop in size, down to 3ft NE swell, but with a bit more period at 9 seconds. The wind is still cross-off, so it remains rideable, just nothing special. Tuesday the 8th onward falls away into a very flat and unremarkable pattern. There’s a small bump of 3ft from the south on Thursday the 10th, but it’s only 8 seconds with a strong offshore wind, making for a clean but very weak day for the experts only. The energy is minimal at 85.
We then hit a major drought. From the 9th of September all the way through to the 16th, it’s a ghost town. Tiny, unrideable waves, if any. Most days the energy is in single digits. Honestly, it looks more interesting for the kite crew than us paddle surfers on many of those days with the strong cross-off winds.
Then, on Thursday the 17th, there is a more significant swell due from the NE at 4ft with a 7-second period and a combined energy of 153. The wind is strong and cross-off from the SSW. It'll be clean and punchy, but that 4ft is still manageable for most, though the short period will make it a bit dumpy. It’s a solid option for those who can wait. The 18th drops off again.
So, to keep it simple: Sunday afternoon the 6th is your clear winner. Thursday the 17th is a decent second option but a long way off. The rest of the time, the board stays in the car.
Stay frothy,
Rusty

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