The Lowdown
Right then, let's have a look at what's on the cards for Coastguard Beach.
Well, I gotta be straight with you, the next couple of weeks are looking pretty bleak for a proper paddle. We've got a long stretch of small, weak, and messy conditions ahead. The first real window doesn't even show up until a week from Wednesday, on the 23rd of September. Before that, it's all tiny dribbles with poor surf conditions day after day. The swell energy is barely registering, so it's a proper flat spell.
The only time the ocean shows any life is on the 23rd of September, Wednesday morning. We get a bit of a lift with 5ft of swell from the ESE, and it's got a bit of period at 8 seconds. The wind is set to be a clean cross-offshore breeze from the NW, which should tidy things up nicely. This is going to be the standout, but that 5ft is right on the edge for beginners. The rest of that day and the days following are a write-off with howling onshore gales battering the coast.
Then there's a glimmer right at the end of the outlook, on Sunday the 27th of September in the morning. We're looking at clean, glassy conditions with a light NNW breeze, and a tiny 2ft E swell. It's surfable, just ordinary.
The water temperature is around 67°, which is pretty normal for this time of year, so a spring suit will do you fine for those cleaner moments.
Bottom line: if you're desperate for a paddle, the morning of the 23rd of September is your best bet to get a few chest-high waves, but don't expect much else. For the rest of it, the kite boarders might have a better time of it when that onshore wind really kicks in.

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.
