The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, the next couple of weeks are looking pretty flat and ordinary for the most part. There’s a real lull setting in. We’ve got a long stretch coming up where it’s going to be tough to find anything decent to surf.
The main spot to keep an eye on is Coastguard Beach. It’s a beginner-friendly, exposed beach break. The water temp is sitting at about 66.6°, which is pretty average for this time of year, no major surprises there.
We do get a tiny pulse of energy arriving on the morning of Thursday, the 30th of July. Swell bumps up to 5.2ft from the NE, with the combined energy hitting 320 (moderate). The wind is a strong cross-offshore from the NW, which will keep the surface clean. That afternoon, it pushes a bit bigger to 5.9ft NE with energy at 323 (moderate) and a cross-offshore breeze from the WNW, so the conditions stay clean. It’s a beach break though, and with that size and a short period of 6 to 7 seconds, it will be a bit of a messy, washed-out affair. Honestly, with the strong wind and setup, this might be more interesting for kite surfing than paddle surfing.
The best chance for a proper surf comes on Friday morning, the 31st of July. Swell drops back to 3.6ft from the NE, but the combined energy is still moderate at 213. The wind goes light offshore from the WSW – that’s 6 mph, clean conditions. The period is still short at 7 seconds, so it’s not going to have much push, but it’ll be the cleanest surf of the whole run. Expect some company though – crowds are sometimes an issue here.
That afternoon, the wind goes glassy with a 2.9ft NE swell, but the energy drops right off to 96 (weak). It’ll be surfable but very ordinary.
After that, from Saturday the 1st of August right through to the end of the forecast on the 9th of August, it’s a dead zone. We’re talking tiny waves, mostly under 1.6ft, with no real energy. A few mornings show clean glassy conditions or light offshore breezes, but there’s just no swell to work with. It’s a long, flat run.
So, the only real standout is Friday morning, the 31st of July. It won’t be epic, but it’s the best of a quiet bunch.

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.
