The Lowdown
Alright folks, Rusty here. Let’s be straight with you right from the start. I’ve looked this whole 16-day run over, and honestly, it’s a tough one. The only break on the menu is Coastguard Beach, and for the vast majority of this period, the surf just isn’t worth paddling out for. You’re looking at a long, quiet stretch where the ocean’s mostly asleep or blown out.
We’ve got a big gap of nearly two weeks with no real recommendations. Starting now and running right through until about the 21st, there’s nothing to get excited about. The first week is especially grim – tiny little waves, mostly under 2 ft, with weak combined swell energy barely cracking 61 (Weak) on the best days. Winds are often fresh and messy, and the swell directions are all over the shop. Even when the wind drops, the waves are just too small to do anything with.
Now, after that long dry spell, we get a little flicker of hope. On the morning of Monday the 21st of September, the swell bumps up to 5 ft from the NE, with the combined energy finally climbing to 187 (Moderate). The period is a short 7 seconds, so it’ll be a bit weak and bumpy, but the wind is light and cross-offshore from the WNW, which will keep it clean. The wave comment says "surfable waves but very ordinary conditions," and I’d agree. For a spot that’s been flat for weeks, it’s the one and only standout. If you’re desperate for a paddle and you’re a beginner, this is your window, but don't expect anything epic. The afternoon fades quickly as the wind shifts.
So there you have it. A long, long wait for a single, ordinary morning. It’s a lean run for Coastguard Beach, but sometimes that's how it goes. The forecasts can always change, so don’t completely write it off, but this one’s mainly for the kite crew and the folks just happy to be in the water.
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.
