The Lowdown
Alright, let’s get real about this stretch. I’m Rusty, and I’ve been watching this forecast for Coastguard Beach. I gotta be straight with you: this is a tough run. The whole 16-day window looks pretty flat and lifeless. There are no real standout swells lined up, and the wind is rarely playing nice.
The first surfable moment doesn’t show up until Sunday afternoon, September 6th. Even then, it’s not something to get excited about. We’ve got a tiny 4 ft swell from the NE, with a period of 7 seconds—so it’s short-period, windswell-type stuff. The combined energy is only moderate (141). What saves it is the wind: a light NNW breeze swinging cross-offshore, which makes for clean, smooth faces. That’s your best bet across the whole outlook, but don’t expect much power. It’s a beginner-friendly wave with that height, but it’s not going to bowl you over.
The water temperature is about average for this time of year, so no crazy surprises there.
Monday (September 7th) afternoon has a tiny 2 ft swell from the NE with a 9-second period, and the wind goes offshore from the W at only 6 mph. That’s clean, glassy conditions, but the swell is too small to really surf—just ankle-biters.
After that, it’s a long stretch of nothing. From Tuesday morning all the way through to the end of the forecast, the swell barely registers. Heights hover around 0.3 ft to 1.0 ft, with combined energy in the single digits or low teens. That’s weak—really weak. The wind is often clean, but there’s no wave to work with.
For a spot like Coastguard Beach, which is consistent, this is a real dry spell. It’s the kind of period where you’d be better off checking the tides and hoping for a change in the charts. The setup is exposed, but it’s just not catching anything.
No standout days. No hidden gems. Just a lot of clean, flat water. If you’re a kite surfer, those 15 to 19 mph afternoons mid-period might look interesting, but for a paddle surfer, it’s a no-go.

A general guide to surfing at Coastguard Beach can be found by selecting the local surf guide option on the grey menu.

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.
