The Lowdown

Alright, Rusty here, let’s get into it.

First up, I gotta be straight with you – for the entire 16-day window, we’re looking at a real flat spell at Coastguard Beach. There isn’t a single session worth paddling out for. The whole forecast is a struggle for any kind of surfable wave. The combined swell energy barely ever gets past weak, topping out at just 73 early on the 22nd of August, and that’s with a messy, short-period 3.3ft swell from the ENE and a cross-onshore breeze. Not a good look.

From Saturday the 22nd of August right through to Sunday the 6th of September, it’s a dry run. The swell heights are tiny, mostly below 1.6ft, with periods all over the place but doing nothing to help. Even when the wind goes offshore or glassy, like on the 29th of August with a glassy afternoon and a tiny 1.3ft SE swell (energy 23), there’s just no power to work with.

For a break like Coastguard Beach that’s consistent, it’s a bit of a surprise to have such a long stretch of nothing. But these flat spells happen. The water temp is running about 69.3°F on the 22nd, which is pretty normal for this time of year. Honestly, if there’s any wind at all and the swell stays this pathetic, it’s more of a kite-surfing setup than a paddle-surfing one. There’s nothing to get excited about here. Hang tight, and check back.

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.
