The Lowdown

Righto, grab a coffee, sit down, and let’s talk about the surf ahead. I’m looking at Coastguard Beach. Gotta be straight with you, it’s a rough 16-day window for this spot. The first solid bit of swell doesn’t show until way down the track, so we’re looking at a long stretch of flatness or tiny junk before that. We’re talking about a gap of nearly two weeks where the waves are basically absent or so small it’s not worth paddling out. That’s a long blank run, and it’s not abnormal for this area when the conditions just don't align.

Alright, let’s get into it. For the first week, from August 9th through to around August 21st, it’s pretty grim. Swell heights are mostly hanging around 0.3 ft to 1 ft with periods that are short and weak – like 6 to 9 seconds. The energy is low, with combined readings mostly under 30 – that’s barely a ripple. Winds do swing offshore or glassy at times, which is nice for the soul, but with nada to ride, it’s just a clean surface. A few afternoons like August 11th Tuesday arvo go glassy, but there’s only 0.3 ft of swell. It’s a flat spell. For beginners, it’s safe to say there’s no real surf to learn on, and for anyone else, it’s strictly a tanning mission.

Now, the one standout in this whole outlook shows up on Monday the 24th of August, in the morning. That’s a long way off, so take it with a grain of salt, but it’s the best we’ve got. Swell builds to 6 ft coming from the NE, with a period of 9 seconds. The combined energy jumps to 515 – that’s moderate to strong, and you’ll feel it. A 6 ft swell is getting up there, and with a NE direction, it’s hitting the coast from a different angle than the usual tiny stuff. The wind is a fresh offshore from the SW at 19 mph, and that’s clean. For the few locals who stick it out through the flat, this could be a decent session. Keep in mind, though, the water temp for this break is about average for the time of year, nothing crazy.

This is what it is, folks. A bunch of quiet days with a single, distant window of hope. Stay patient. 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.
