The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for Coastguard Beach over the next couple of weeks.
Honestly, I’m looking at this forecast and it’s pretty grim. For the entire 16-day window, there’s nothing worth paddling out for. The wave energy is almost non-existent, with the combined energy of all swells directed here barely cracking 20 to 30 at its best, and mostly sitting in the single digits or low teens. The swell heights are tiny, hovering around 0.3 ft to 2 ft, and the periods are short, mostly around 6 to 9 seconds, which is just weak, wind-slop energy. The only time the combined energy even gets into the moderate range is on Monday afternoon, the 3rd of August, hitting 154, but that’s with a swell of only 4 ft from the S and a period of 8 seconds, coupled with a strong breeze from the SSW at 28 mph. That’s a blown-out, messy setup, more suited to kites than paddles.
The winds are a major problem here. While there are a few sessions with a clean look, like Saturday morning the 1st of August with a light cross-off, the swell is just too small to do anything with. The water temperature is 69°F, which is about average for the time of year with a 0.7°F anomaly, so at least the water is pleasant if you’re just dipping your toes. But for surfing? There’s a long dry spell. From the 1st right through to the 16th of August, there isn’t a single standout session. The forecast is a tough one for Coastguard Beach – it’s a consistent break, but it’s just not got any juice coming in. Don’t hold your breath; sometimes you get a blank run like this, and it’s just the way it goes.
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.
