The Lowdown
G’day, I’m Rusty, and here’s the look for Coastguard Beach. This is a long stretch of nothing, so let’s get into it.
Honestly, it’s a dead zone for nearly two weeks. From the 1st of August through to the morning of the 15th, it’s flat and lifeless. The biggest swell in that period is barely 3 feet, with periods mostly under 8 seconds, and the combined energy tops out at 70 (70). Winds are all over the place – cross-off, cross – but with no swell to work, it’s just a glassy pond. The morning of the 8th has a light offshore breeze from the W, but the swell is a pathetic 0.3 feet – not even a ripple. You’d be better off taking a nap.
Then the morning of the 15th offers a little tease. A 7-foot swell from the NNE with a 6-second period and a clean cross-off wind from the NNW. The combined energy hits 555 (555) – moderate. But the wave comment says it’s marginal, and the score is 2/10. It’s too big for beginners, but the short period makes it choppy and hard to ride. Not a goer.
The real deal is the morning of the 16th – Sunday morning. This is the only standout. A 10-foot swell from the NE with an 11-second period, and the combined energy is a massive 1729 (1729) – strong. The wind is glassy, dead calm, from the NNE at 3 mph. The water temp is about average for the season, nothing wild. The swell direction is NE, not quite the optimum SE, but with that size and clean conditions, it’s going to be a beast. The wave comment warns the swell is too big for this break. At 10 feet, it’s expert-only, and being a beach break, it could be a close-out. It’s a heavy, powerful wave for the brave. The afternoon of the 16th drops back to 1 feet, so the window is tight.
In short: a long, flat spell from the 1st to the 14th, a marginal blip on the 15th, and then a heavy, expert-only session on the morning of the 16th. The 16th is the only day to circle, but it’s not for everyone.
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.
