The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ over the next couple of weeks.
Alright, I gotta be straight with you – this is a tough one. The whole 16-day window is flat as a pancake for Coastguard Beach. We’re lookin’ at a run of poor surf conditions from start to finish, with no standouts to get excited about. The swell is tiny, barely nudging 1.3 ft at best, and for most of the time it’s sitting around 0.7 ft or less. The combined energy of all swells directed here is weak, with values like 66 dropping down to just 1, so there’s no real push in the water.
The first few days, from Friday the 31st of July through the weekend, offer a little 1.3 ft SE swell, but it’s pretty much a non-event. Friday afternoon does go glassy with a calm wind, which is nice, but there’s nothing to ride. Saturday and Sunday the wind picks up, and the swell drops even more. This pattern just keeps going into the next week.
By the 7th of August, there’s a brief flicker of 2.6 ft from the south, but the period is a short 4 seconds, so it’s gonna be weak and bumpy. The wind is cross-off, so it’s clean, but with such tiny, weak waves, it’s not worth paddling out for. The rest of the week is more of the same: tiny swells, mostly cross-off winds, and combined energy in the single digits or low twenties.
The second week, from the 10th of August onward, is even worse. Swell heights drop to 0.3 ft or 0.7 ft, and the energy is minimal. There’s a glassy moment on the morning of the 13th of August, but with only 0.7 ft of swell, you’d be better off stretching on the sand. The water temperature is about average for this time of year, nothing out of the ordinary.
Honestly, this is a stretch where the ocean just isn’t cooperating. Wait for the next swell pulse – forecasts can change, and it won’t stay this poor forever.

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.
