The Lowdown
Alright, folks, let me level with you. Coastguard Beach is in a dead zone for the next two weeks. The first real ripple of hope doesn’t show up until Thursday, August 13th, and it’s a tiny one.
From the 30th of July through to the 13th of August, it’s a big fat zero. The swell is laughable – between 0.3ft and 2ft – with combined wave energy readings that are mostly weak, in the single or low double digits (like 190, 67, and 23). Winds are messy, cross, cross-off, and even onshore, keeping the surface choppy or just too small to care. Water temp is about 69°, which is normal for the season, so no surprises there.
The only real chance you get comes on Thursday morning, August 13th. We get a pulse from the south at 3ft, with a period of just 6 seconds. That’s a short-period, wind-driven bit of energy, not a groundswell, so it’ll be a bit raggedy. The combined energy hits 107 (moderate), which is the best we’ll see. Winds are SSW at 15 mph, blowing cross-offshore, keeping it clean. By the afternoon, it drops to 2ft, and the wind howls to 22 mph, still cross-off but getting strong. Since it’s a beach break, with this short-period stuff, it’s going to be a bit of a mess – probably more fun for a kite surfer than a paddle surfer. For a beginner spot, 3ft is okay, but the short period makes it a challenge.
If you’re really jonesing, Thursday morning, August 13th, is your only play. It’s not a standout, just a brief window of something that’s not completely flat. Otherwise, pack your board away for a bit.

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.
