The Lowdown
G'day, Rusty here. Look, I've had a good hard look at the charts for Coastguard Beach, and I'm not gonna sugarcoat it: the next 16 days are a real struggle for surf. We're staring down the barrel of a long, flat spell with nothing pushing in. The first real glimmer of anything doesn't show up until Monday the 27th of July, and even then, it's a marginal call. That's a solid two-week gap with no real recommendations for a paddle.
The water temp is sitting at 67°, which is about average for the time of year, so at least you won't be freezing while you're waiting.
The first noteworthy session arrives on Monday morning, 27th July. We've got a weak 4ft swell pushing in from the NE, but it's a short-period, choppy wind swell at just 5 seconds. The combined energy is weak, sitting at only 71. The wind is light and cross-offshore from the SW, which will keep the surface clean, but the waves themselves are just ordinary. It's surfable, but you won't be telling your mates about it. The afternoon cleans up nicely with that offshore wind, but the swell drops right back to 3ft with even less energy (61).
The rest of the forecast into the 28th is pretty much the same story: small, weak, and uninspiring.
There's just no standout in this window. The swell is too small, the period is too short, and the energy is almost non-existent for the vast majority of the time. If you're desperate for a splash, the only window is Monday the 27th, but honestly, this is a period where you're better off checking the cams and hoping for a last-minute change. The forecasts can always shift. For now, it's a long wait.
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.
