The Lowdown
Alright folks, Rusty here, and I'm staring at Coastguard Beach and it's a tough one. We’re in for a real dry spell. The pattern starts out flat and stays that way for a solid week and a half, just a whole lot of nothing and messy conditions. The wind is mostly cross or cross-off, and even when it does clean up, there’s no swell to back it up.
The only day that even gets a mention is Friday, September 18th, in the morning. That’s the one real standout, and it’s more of a whisper than a roar. You’ll get a glassy, mirror-flat surface thanks to a slight air from the east-northeast. The swell is a tiny 4ft from the northeast, but the period is a short 6 seconds, so the waves are gonna be weak and fat, with a combined energy of 114. It’s surfable, but it ain’t pretty. Water temp is pretty much what you’d expect for this time of year, nothin’ weird there.
Before that? Nada. Swell is mostly under 3ft, with periods down to 4 or 5 seconds – that’s just wind slop. A few mornings like Tuesday the 8th and Wednesday the 9th look clean, but the swell is pathetic, like 2ft to 2ft. Not worth the drive. This spot is usually consistent and good for beginners, but when the ocean shuts down, even the best spots go quiet.
So, your only real option is to wait for that Friday the 18th morning. It’s gonna be clean, small, and ordinary. It’s the best we got, but it ain’t much.
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.
