The Lowdown
Alright folks, Rusty here. Let’s get straight into it. To be honest with you, it’s a pretty bleak run ahead. We’re looking at a long stretch of nothing special, and if you’re itching for a wave, you’ll be waiting a while.
The first hint of anything that’s actually surfable comes on Saturday the 5th of September. Up until then, it’s a dry spell. From the 26th of August right through to the 4th of September, it’s just a whole lot of flat or poor surf conditions. You’d be fighting a losing battle out there.
The only real stand-out, and I mean the only one worth talking about, is a promising but less certain window on Saturday the 5th of September. Coastguard Beach looks like it might just offer something. We’ve got a clean morning on the cards with a light breeze blowing cross-offshore. The swell is tiny, only 3 ft, coming from the East. The wind is light and clean, which is a major positive. The combined swell energy is weak (90). It’s a beginner spot, so the size is fine for that crew, but it’s not going to get the heart racing. The crowds are listed as ‘sometimes’, so you might have a few others with the same idea.
After that, it’s more of the same. The following week looks like a write-off with tiny, weak swells and mostly poor conditions. The water temperature is about average for this time of year, so you won’t need a steamer, but you’ll need a lot of patience.
That’s the reality of it, folks. A long wait for a very ordinary day. Keep your eyes on the forecasts, though. It tends not to stay this poor for long.
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.
