The Lowdown
Alright, Rusty here. Let’s look at the local situation for Coastguard Beach.
Honestly, it’s a tough stretch ahead. The whole outlook is a long, flat spell with barely a ripple worth paddling for. There are no standout sessions at all, and I’m looking at a solid 16-day run where the surf just isn’t on. For the first week, from the 28th of July right through until the 3rd of August, it’s all tiny, messy, or just plain flat. The biggest bump we see is on the morning of the 29th of July, with a short-period 4 ft swell from the ESE, but the wind is a fresh cross-onshore at 19 mph, making it lumpy and poor. The combined energy is only 80 (weak), and it’s just not worth suiting up. The following days are dominated by tiny waves under 3 ft, crossed-up winds, and conditions that are either choppy or have that nasty cross-chop. Thursday afternoon the 30th of July does show a slight uptick in energy to 209 (moderate) with a 3 ft SSE swell and a 8-second period, but the conditions are still marginal and only score a 1. It’s not going to be any kind of classic.
We then hit a truly flat patch from the 1st of August right through to the 11th of August. Wave heights barely hit 1 ft, and the combined energy is often in the single digits or low teens. You’d be bobbing around on a lake. There is one interesting moment on the morning of Monday the 10th of August: a completely glassy morning with no wind and a 1 ft SE groundswell with a 10-second period. But it’s only 1 ft, and the energy is just 30 (still very weak). For a beginner spot that is consistent, even this is too small to ride.
Finally, on Tuesday morning the 11th of August, a pulse of 4 ft SSW swell with a short period of 5 seconds rolls in, but it’s crossed-up with a gentle breeze and the combined energy only hits 106 (moderate). It’s still listed as poor surf conditions. Then we fade back to flatness for the rest of the outlook.
For a break that’s exposed to the SE, with an optimum from the SE, we just aren’t getting any clean, rideable swell with the right wind. This is a blank run that’s more normal for the area during this time, and the water temp is about average at 68°. With the persistent poor conditions and mostly short-period, weak swell, honestly, the setup looks more interesting for kite surfing than paddle surfing. The wind is the only consistent thing here.
Better luck next time, folks. Keep an eye on the charts. This is Rusty, signing off.

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.
