The Lowdown
Alright, Rusty here again. Let’s be real – this forecast is a bummer. We’re looking at a long stretch of flatness with almost nothing to get excited about. The first real chance of a wave doesn’t show up until late in the game.
For the first week and a half, from now through the end of August, it’s a flat and messy picture. Swell heights barely touch 3 feet, and when they do, the wind is all over the place – cross-on, cross-shore, or just plain strong. The combined wave energy is weak, sitting in the low double digits to the 30s and 40s, which tells you there’s no power in the water. The only clean conditions come from the cross-offshore winds on the 24th and 25th, but with swell barely at 1 feet and a short period of 6 seconds, it’s a paddle, not a surf. The water temp is about 69°F early on, right around normal for this time of year.
Things get a little interesting, but not by much, on Sunday the 30th of August. Coastguard Beach sees a brief moment of glassy conditions in the morning. The swell is only 3 feet, coming from the NNE at a short 6 seconds, and the energy is still low at 65. It’s surfable, but very ordinary. It’s the cleanest we’ll see in a while, but it’s not a standout.
Then we hit a proper gap. From the 31st of August right through to the 3rd of September, the wave heights are tiny, the energy is weak, and the conditions are just poor. Not a single session worth getting excited about.
Finally, there’s a flicker of life on the morning of Thursday the 3rd of September. We get a bump in swell to 4 feet from the south, with a short period of 5 seconds, but the energy climbs to 115 (moderate). The wind is a light cross-offshore from the NNW, keeping things reasonably clean. It’s still not a classic, and the short period means it won’t have much push, but it’s the most surfable we’ve seen in a fortnight. It’s the only real standout in this whole outlook, and it’s a very low bar. For a beginner, the 3 and 4 foot days are the only ones even worth considering, but don’t expect any magic.
Truth is, with such a consistent break and barely any surf, it’s one of those blank runs that happens. Forecasts can change, but right now, it’s a waiting game.
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.
