The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
To be straight with you, this is a pretty bleak stretch for Coastguard Beach. We’re looking at a solid 16-day window, but the first week and a half is basically a write-off. There’s a gap from now until the 27th of July where the surf is nearly non-existent or just plain ugly. The energy is weak, with the combined swell energy sitting at a paltry 26 on the 25th, and the wind is mostly cross or onshore, leaving the water messy. You’ll be staring at flat, choppy lines.
The only flicker of life comes on Monday, the 27th of July. The morning shows a little 2ft swell from the SE, with a period of 7 seconds. The wind is a light offshore from the SSW, which will clean things right up. It’s still small, and the combined energy is only 92, so it’s not going to be a world-beater, but it’s the first time you’ll find a clean, surfable wave. The water temp is about average for the time of year here, so no surprises there.
After that, it’s right back to the doldrums. The rest of the run into early August is tiny, with swell heights rarely scraping 2ft. The wind tries to turn offshore a few times, like on the 31st of July with a W wind, but there’s just no swell to push it. The energy readings drop into the teens and low twenties, which is about as weak as it gets.
Honestly, if you’re desperate, the 27th of July morning is your only real shot, and even then, it’s a beginner-grade wave. For the rest of the run, I’d save the gas money. The ocean is having a nap.
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.
