The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Right off the bat, it’s a pretty grim stretch. We’re lookin’ at a solid 6-day gap with no real surf to speak of. From the 27th of July right through to the 1st of August, it’s mostly tiny, junky waves with onshore or cross-shore winds messin’ everything up. The water temp is sittin’ about average for this time of year, so nothin’ to write home about there.
Thursday morning the 30th of July is the first time we see anything remotely rideable down at Coastguard Beach. The swell bumps up to 4 ft from the east, but the energy is weak (123) and the period is a short 6 seconds. It’s glassy though – dead calm wind – so the surface will be clean. Still, it’s ordinary at best, a real knee-slapper.
The one true standout, the window you wanna circle, comes on Monday the 3rd of August. Monday morning, the stars finally align. We’ve got a clean 5 ft swell rollin’ in from the southeast, with a 10-second period – that’s proper groundswell energy. The combined energy jumps to 478, which is moderate to strong, and the wind is offshore, light and clean from the west. This is the best of the whole forecast. For a beginner-friendly spot like this, 5 ft is a fun size, not too big, and with offshore wind it’ll be glassy. The only downside is the swell direction is southeast, right on the money for this exposed break, so it’ll be workin’ well. Crowds are possible though, so get there early.
After that beauty, it fades fast. The rest of the week into the second week drops off into tiny slop again, with nothing else worth paddlin’ out for. The 10th and 11th of August are dead flat with almost no energy.
So, keep your eyes on Monday the 3rd of August. That’s your day.
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.
