The Lowdown
Alright, let’s get real about the next few weeks at Coastguard Beach.
Honestly, it’s a grim stretch for paddle surfing. We’ve got a lot of small, weak, and messy conditions lining up, with the first real chance of anything rideable not showing up until Sunday the 23rd. Before that, it’s a whole lot of nothing—tiny, short-period slop under 3ft, bumpy cross-shore winds, and just overall poor surf. There’s a brief pulse of energy on the 22nd, but it’s still onshore and messy, and I’d rather save my energy.
Finally, on the morning of Sunday the 23rd, we get a bit of life. Swell climbs to a clean 4ft, coming from the NE with a period of 6 seconds, and the combined energy kicks up to a moderate 108. The wind is light cross-off from the SSW, which makes it glassy and clean. It’s surfable, and for the first time in a week and a half, it’s not a complete waste of time. The water’s running much warmer than normal for this time of year, around 73°, which is a nice little bonus. The afternoon backs off a touch to 3ft but stays clean.
After that, the plug gets pulled again. Monday the 24th drops back to nothing. There’s a little more swell around Thursday the 27th, but the wind is straight onshore, and it’s just not worth the paddle out.
Look, as the days go on, forecasts can shift. The fact that this spot is pretty consistent means a proper run of waves ain’t far away, but based on what we’ve got now, don’t plan a trip around it. Keep the board in the car for Sunday morning if you can—that’s your one and only window.

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.
