The Lowdown

Alright, grab your board and let’s talk about the next couple of weeks. My name’s Rusty, and I’ve been staring at the charts for our stretch of coast, and I’ll be honest with you—this is one of those runs where you might be better off waxing the kayak or fixing a fin than paddling out. The swell window is looking pretty flat and disorganized for a long stretch.

We kick things off with a real dud. The first few days are straight-up poor. Through Tuesday the 4th and into the rest of the week, we’re looking at tiny, weak surf, mostly under a foot and a half, with a lot of cross-offshore breeze messing up what little there is. The energy is just pathetic—combined swell energy values are in the low teens or single digits, which is as weak as it gets. You’d be paddling for nothing.

The water temp is sitting at 67°, which is about normal for this time of year, so at least you won’t be freezing while you’re sitting there waiting for a wave that isn’t coming.

There’s a little hiccup of hope early on the 5th. Wednesday morning, the wind drops right out to glassy, and the swell is a knee-high 1ft from the southeast. But it’s still poor surf conditions, and the period is a short 7 seconds. It’s clean, but it’s tiny. Not worth rushing out for unless you’re desperate for a splash.

The rest of that week just fizzles. We’ve got some offshore breezes on Friday the 7th and Sunday the 9th, but the swell is still minuscule—0.3ft to 1ft. The energy is nothing. You’re talking about ankle-biters at best.

The whole first week is a washout, honestly. We’re looking at a gap of about 10 days with no real surf on offer. It’s a dry spell, and it’s going to test your patience.

Now, let’s talk about the one glimmer in this whole forecast. It’s not until Saturday the 15th that we see anything with a pulse. Saturday morning, the wind goes glassy—dead calm, not a breath of air. And we finally get a little bump of swell: 2ft from the south-southeast, with a period of 9 seconds. It’s not huge, but it’s the biggest we’ve seen, and the combined swell energy jumps to 66, which is the only time we get anywhere near moderate. It’s still only a 1/5 on the good surf scale, but it’s the only surfable waves in the whole damn window. Coastguard Beach is the spot, exposed to that south swell, and with the glassy conditions, it’ll be the cleanest it’s been all fortnight. It’s a beginner wave anyway, and this is about as friendly as it gets. But don’t expect much—it’s still small.

After that little blip, Sunday the 16th and into the final stretch, it’s back to the same old story. Tiny, weak, and mostly onshore or cross-shore winds. The energy drops right back down to nothing. There’s a chance of a little more size early in the second week, but it’s so far out I wouldn’t bet the farm on it. The long-range stuff is promising but about as reliable as a weather forecast for next month.

So, here’s the bottom line: if you’re a beginner, Saturday the 15th is your day. It’s clean, it’s small, and it’s the only real option. For everyone else, this is a good time to catch up on board repairs or watch the cams from the couch. It’s not looking great, but that’s the way it goes sometimes. Forecasts change, and this flat spell can’t last forever.

Stay salty.

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.
