The Lowdown

Alright folks, Rusty here. Let's have a look at what the next couple of weeks are serving up for us.

To be straight with you, the 16-day window is looking pretty grim for a proper surf. There’s a long stretch of flat to tiny, poor-quality waves that’s going to be tough to sit through. The first real chance of anything worth paddling out for doesn't show up until Thursday the 24th of September, and even then, it's only just surfable. Before that, we're looking at a solid two-week gap where the conditions are just not cooperating.

When things finally try to turn around on the 24th, Coastguard Beach might have a tiny spark. Thursday morning we could see a 3ft wave coming from the ENE with a period of 8 seconds. The wind will be offshore from the WNW at 16 mph, which will clean it up nicely, and the water temp is sitting at about 66°F, which is pretty normal for this time of year. The combined swell energy is a modest 133, so it's not a powerhouse, but at least there's a little bit of push. The wave comment does say "surfable waves but very ordinary conditions," and the rating is low, so don't get your hopes up for anything epic. The ENE swell direction is a direct hit for this spot, so it’s the best of a bad bunch. If you're desperate for a paddle, that's your window, but it's more for the beginners looking for a gentle intro.

Otherwise, through the rest of the period, the swell is either tiny, the wind is all over the place, or both. We see some moderate combined energy values like 125 and 175 pop up on the 22nd and 23rd, but the wind is cross-onshore and onshore, making a mess of it. The 4ft swell on the 22nd afternoon has a combined energy of 125, which is decent, but the light cross-onshore wind won't help the shape much.

In short, it's a pretty bleak outlook for the next two weeks. Don't expect any standouts. The only thing worth mentioning is that morning on the 24th, but it’s far from a sure thing. I’d keep an eye on the forecast, because things can change, but for now, it’s looking like a good time to wax your board and wait.

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.
