The Lowdown
Right then, let's have a look at what's on offer for the next couple of weeks at Coastguard Beach. It's a consistent, exposed beach break that's best for beginners, and it likes a SE swell. Straight off the bat, I gotta be honest with you, the next ten days or so are looking pretty grim. We've got a real flat spell on our hands. There's a big gap from now until around the 13th of September where there's just nothing worth paddling out for. The swell is tiny, the winds are messy, and the overall wave energy is weak, often well under 100. It's a proper dry spell.
Now, looking further ahead, things start to stir a little. On the morning of Sunday the 13th of September, we finally see a pulse of life. The swell bumps up to 3ft from the NE, with a period of 7 seconds. The wind turns offshore from the W, which is a major positive, keeping things clean. The combined energy climbs to 72, but it's still only described as "surfable waves but very ordinary conditions." It's not a standout, but after such a long wait, it's the first real chance to get wet.
Following that, the 14th of September (Monday) brings some glassy conditions with the wind dropping right off, but the swell is tiny and mixed up, so don't expect much.
The next little pulse to keep an eye on is the 15th of September (Tuesday). The morning shows 3ft from the NE, but the period is a short 5 seconds, and it's paired with a strong cross-offshore wind. The energy is still moderate at 62. The afternoon is a write-off with a cross-onshore wind making it choppy. For a beginner-friendly spot like this, a 3ft NE swell with those short, choppy waves won't be great. This setup is more interesting for kite surfing than paddle surfing.
Honestly, mate, the only thing that even gets a nod is that Sunday the 13th morning session. It's not going to be epic, but it's the best of a pretty average bunch. The water temp is running about 3° warmer than average for this time of year, sitting at 69°, so at least you won't freeze while you're waiting for a wave.

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.
