The Lowdown

G’day, Rusty here. Gotta be straight with ya – it’s a pretty bleak run of surf ahead for Coastguard Beach. We’ve got a long stretch of tiny, wind-affected junk and nothing that’s really gonna get the heart pumping. It’s a consistent beginner’s spot, but even for a learner, the quality just ain’t there for the bulk of the next two weeks.

The water temp is sitting around 67°F, which is about average for this time of year, so at least the water won’t be a shock.

We start with the first real recommendation, and it’s a tough one. On Saturday the 12th of September, the swell is barely a ripple at 0.3ft from the east with a 10-second period. The combined wave energy is a very weak 4. Winds are onshore and light in the morning, turning cross-onshore and moderate by the arvo. It’s just poor surf conditions all day – flat and messy.

Sunday the 13th isn’t any better. We get a tiny bump to 2ft on Sunday morning from the SSE, but it’s a short-period wind swell at 4 seconds. The combined energy is still only 24, and the wind is a moderate cross-onshore. Sunday afternoon brings heavy rain and a messy 1ft. Nothing to paddle for.

Monday the 14th sees a cleaner setup with cross-offshore winds, but the swell is a weak 1ft from the SE at 6 seconds. Combined energy is a pathetic 15. It’s clean but totally flat.

The whole week just drags on like this. Tuesday the 15th gets up to 3ft from the NE, but the period is a horrible 5 seconds and the winds are onshore. The energy nudges up to 43, but it’s still choppy and poor.

It isn’t until Wednesday the 24th of September – over a week and a half away – that we see a real change in the water. The swell jumps to 5ft from the east with a longer 9-second period. The combined energy rockets up to 617, which is strong to very strong. But before you get excited, the wind is a strong onshore breeze, and it’s labelled as poor surf conditions. That much swell with that much onshore wind at a beach break like Coastguard is gonna be a washing machine – honestly, this setup looks more interesting for kite surfing than paddle surfing. The following days see similar energy levels (362 on Thursday arvo, 207 on Friday morning) but all with strong onshore winds and rain, keeping it blown out and messy.

Honestly, there’s no standout, no hidden gem in this forecast. It’s a long, flat spell broken only by a period of messy, onshore swell that’s no good for anyone. Keep the board in the shed and watch the forecast change.

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.
