The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Coastguard Beach over the next couple of weeks. I’ll be straight with you, it’s a pretty grim run for the most part, so don’t get your hopes up too early.
The overall pattern is quiet, real quiet. We’ve got a long stretch of tiny, weak swell and wonky winds. It’s the kind of forecast that makes you want to check the wax collection instead. There’s a big gap of nothing much, then a brief flicker of hope right at the very end of the window.
The first real chance to wet a line doesn’t come until Friday morning, the 31st of July. We get a tiny pulse of 2ft swell from the SE with a period of 9 seconds. The combined energy is weak, sitting at just 73. The morning starts with a clean cross-off breeze from the NNW at 9 mph, which is a nice touch. The water temp is a touch above average at 70°, which is about normal for this time of year. It’s surfable, but it’s very ordinary. Honestly, it’s barely worth the paddle.
After that Friday morning, we hit a dead zone. From Friday afternoon all the way through to Sunday the 9th of August, the surf is poor. We’re talking swell heights mostly under 2ft, short periods, and messy winds from the south and southwest. The combined energy readings are all in the double digits or low triple digits, which tells you just how weak it is. There’s a day of glassy conditions on the 5th, but with only 1ft of swell, it’s a lake session. It’s a long, dry spell.
Then, on Monday morning, the 10th of August, we finally get a bit of a pulse. The swell jumps to 5ft from the S, with a period of 7 seconds. The combined energy climbs to 271, which is a moderate kick. The wind is light cross-off from the SSW at 9 mph, keeping things clean. This is the standout of the whole forecast. It’s not a classic, but it’s the only real chance for a decent wave. The swell is just over 5ft, so it’s getting a bit big for total beginners, but it’s still manageable for most. Just be aware it’s a short-period swell, so the waves will be a bit dumpy and less forgiving. The break is consistent, but crowds are sometimes an issue here, so expect some company.
After that Monday, it’s right back to the doldrums. From Tuesday the 11th through to the end of the forecast on the 15th, it’s tiny, weak, and mostly poor again. No real standouts, just a lot of flat, clean water with no energy behind it.
So, to sum it up: if you’re desperate, the morning of the 10th of August is your best bet. It’s the only solid window. The rest of the time, you’re better off doing something else.
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.
