The Lowdown
Alright, I’m not gonna sugarcoat it. Coastguard Beach is looking dead for a long stretch. We’re talking about a serious flat spell.
From now until the 18th of August, it’s just tiny, gutless waves. The wind is generally light, but there’s no swell to push. It’s a solid twelve days of nothing to get excited about. You’re better off waxing your board and waiting.
The one and only window is the morning of Wednesday, August 19. A pulse of 1.5m swell from the ESE is supposed to show up, with the energy really kicking in. The wind is offshore from the west, so it’ll be clean. That’s your one shot. The water is about 67°, which is normal for the season.
But don’t get too fired up. That 1.5m swell is a bit much for a beginner, and it’s a short period, so it won’t have much push. The afternoon gets messy with the wind. After that, it’s back to the flatness.
Honestly, if you’re not a local, don’t bother making the trip until the 19th. That morning is the only thing worth a look.

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.
