The Lowdown

Alright, surfers, Rusty here. Let’s be straight with you. Looking at the charts for the next couple of weeks, it’s a bit of a tough stretch for the lineup at Coastguard Beach. We’ve got a long spell of small, weak, and messy surf coming our way, with a few clean windows but not much push. The start of the period is pretty grim, and the real highlight doesn’t show up until the very end of the run, and even that one’s got a catch.

Right now, and for the next several days, it’s a flat, gutless affair. We’re looking at ankle-biters around 0.3ft with weak energy readings (2). The wind is all over the place, mostly cross-shore, so even the tiny bumps we get are chopped up. It’s a write-off for a proper surf. This poor run carries through the 17th and 18th, with the swell only nudging up to 2ft but still with that weak energy (45-57). The mornings might offer the cleanest look, but there’s just nothing on offer.

The middle of next week, around the 19th and 20th, we see a bit of a change in wind, with some cross-offshore breezes, but the swell stays small and weak. The 19th morning is glassy with a light SW wind and 2ft SE swell, but the energy is still weak (19). It’s tempting to call it a grovel, but it’s still just not quite there. The 20th turns more onshore and choppy, so that’s out.

There’s a real flat patch from the 21st to the 25th. The swell drops right back down, and we’re dealing with tiny waves and, at times, a straight-on wind. The 23rd morning is glassy again with a light NNE breeze and 2ft of ENE swell, but the energy is still weak (24). It’s pretty, but there’s just no power. This is the heart of the waiting game. We’re talking about a solid stretch of days with no real surf to speak of. It’s testing patience, that’s for sure.

Now, we start to see a pulse at the very end of the month. On the 29th, the afternoon looks more promising. We’ve got a 4ft NE swell, and the wind is cross-off from the S at 25 km/h, giving us clean conditions. The combined energy is starting to build, reading 77, which is getting into the moderate range. This is definitely the best looking day so far, but it’s still not massive. Then the 31st rolls around, and this is the standout of the whole period. The swell is a consistent 4ft from the E, and the energy reads a solid 110 across the day, which is the strongest we’ve seen. The wind is a light cross-on from the SSE, so it’s not perfect, but it’s manageable. This is the day to circle. It’s still not huge, and with the direction being a bit cross-on, the beach break might be a little lumpy, but it’s the most surfable we’ve had in a long while. It’s a promising sign to end the run.

So, the call is this: don’t waste your time for the next week and a half. Get other things done. Then, keep an eye on the afternoon of the 29th, but really, save your energy for the 31st. That’s our best bet for some fun, waist-to-chest high waves. It’s not going to be world-class, but it’ll feel like a luxury after this flat spell. Fingers crossed the wind plays nice. This is Rusty, signing off.

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.
