The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' for Coastguard Beach over the next couple of weeks. Honestly, it's a pretty grim stretch for us paddle surfers. The whole period is a bit of a washout, with only tiny, weak waves on offer and the best of it being more of a novelty than anything you'd actually want to paddle out for.
Right off the bat, the water's a touch warmer than normal for this time of year, sitting at 71.2°, but that's about the only silver lining for a while.
The first week is just dead flat, with swell heights barely tickling 0.3ft to 2.0ft. We're looking at a massive gap with no real surf on offer from now all the way through to Monday the 17th of August. The combined wave energy is laughably low, barely hitting double digits, so don't even bother waxing up.
Now, Monday the 17th of August finally sees a pulse of energy, with the swell climbing to 3.9ft from the SSW. It's a short-period windswell though, only 7-8 seconds, so it'll be a bit lumpy and disorganised. The combined energy hits a moderate 157 (Monday morning) and 222 (Monday afternoon), which is the strongest we'll see, but it's still not great. The wind is a messy cross-off to cross, and with the wave quality being poor, this is honestly more of a kite-surfing setup than something for a regular surfer. It's too small for the experts and too weak and choppy for beginners.
After that little blip, it's right back to tiny dribble. Tuesday the 18th has a long-period 0.7ft groundswell at 14 seconds, but that’s way too small to do anything. The rest of the period into late August is just the same story: ankle-biters with weak energy. For a spot that's usually consistent, this is a pretty barren run. Forecasts can always change, but right now, I'd leave the board at home.

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.
