The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this stretch ahead for Coastguard Beach is a bit of a tough one. We’re looking at a very long run of small, weak surf, with the only wave energy that’s any good coming right at the very start. After that, it’s a long dry spell.

For the first and only real window of opportunity, we’ve got Sunday afternoon, September 6th. The swell is tiny at 3 ft out of the NE, with a short period of 7 seconds, so it’s pretty weak, with the combined energy sitting at just 98. That’s not going to fire, but the wind is a cross-off from the NW at 9 mph, so the surface will be clean. The water temperature is 68°, which is 2° warmer than average, so nothing unusual there. This is beginner-friendly heights, but it’s a pretty average session.

After that, it’s grim. From Monday morning, September 7th all the way through to the end of the outlook on Monday, September 21st, the surf just disappears. Wave heights drop to 2 ft or less, and the combined energy never gets out of the two-digit range, mostly staying below 30. There are days of cross-off and even a glassy moment on Saturday morning, September 19th, but with no swell to push, it’s a total flat spell. The only real pest is the wind, which picks up at times, with a fresh breeze of 22 mph from the SW.

So, the honest truth is this: if you’re desperate for a splash, Sunday afternoon is your only shot, and it’s not much to write home about. Otherwise, it’s a long stretch of nothing. For an exposed spot like this, it’s a proper flat spell. Keep the board in the car and maybe keep an eye on the forecast – it can’t stay this poor forever.

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.
