The Lowdown
Alright folks, Rusty here. Gotta be straight with you—this stretch is about as flat as a long weekend in a landlocked town. Let’s break it down.
We’re looking at Coastguard Beach for the whole 16-day window, and honestly, the surf is just a whisper. The first real sniff of anything rideable doesn’t show until Thursday the 30th of July, and even then it’s a weak, small affair. The combined swell energy is a paltry 66, so we’re talking barely a bump. The swell is coming from the southeast at 2 ft, with a period of 9 seconds, so it’s that weak, short-period stuff that doesn’t have any grunt. The water temp is sitting at 69°, which is about normal for this time of year, so no surprises there.
The best of a bad bunch is Thursday morning, the 30th. We’ve got a light cross-offshore wind from the NNW, which will keep the surface clean. It’s surfable but very ordinary—just tiny, mushy lines. After that, it’s back to poor conditions. The swell stays tiny, often under 2 ft, and the wind switches around, mostly cross or onshore, which just messes up what little energy there is.
There’s a flash in the pan on Wednesday the 29th of July, when the swell bumps up to 5 ft from the ESE with a combined energy of 148—that’s moderate energy. But the wind is a fresh 22 mph onshore with rain, so it’s just a choppy, blown-out mess. Not worth paddling out for. That same setup later in the afternoon with 25 mph winds is even worse. If you’re into kitesurfing, that Wednesday might be more interesting than for us paddle surfers.
The rest of the run is a desert. From Thursday the 30th all the way through to Tuesday the 11th of August, we’re looking at mostly flat to knee-high junk, with the occasional clean morning but no swell to back it up. The combined energy drops to single digits on the 6th of August—literally 1. That’s a dead ocean.
So, no standouts here. No proper swell, no decent windows. The break is consistent, but that just means it’s consistently flat. For a spot like Coastguard, this kind of blank run is pretty normal. Forecasts can change, but right now, I’d leave the board in the car and go for a beach walk.
Rusty.

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.
