The Lowdown

Righto, let’s have a look at what’s cookin’ at Coastguard Beach. Bloody quiet out there, mate. The whole 16-day window is a flat spell, no two ways about it. There’s barely a ripple worth paddlin’ for. The first proper surf recommendation doesn’t show up until Monday the 7th of September, and even then it’s a tiny little pulse, nothin’ to get excited about. You’ll be waiting a solid couple of days from now for even that.

The water’s sitting at 68°, which is about 2° warmer than usual for this time of year – a bit of a warm blanket, but nothin’ you’d write home about.

Alright, let’s walk through the schedule. Saturday the 5th and Sunday the 6th are a total write-off. Tiny, weak, messy wind. Saturday morning sees a pitiful 1ft from the east with a 7-second period – that’s just wind slop, and a cross-breeze 16 mph from the north-northeast is choppin’ it all up. The combined wave energy is a measly 26 (weak energy). Afternoon’s worse: 4ft from the northeast with a shocking 5-second period, and 19 mph cross-onshore wind. Just leave the board in the car.

Sunday the 6th ain’t much better. Morning has 4ft from the northeast, 7-second period, but it’s all crossed up by a 19 mph breeze. The combined energy climbs to 177 (moderate energy), but it’s ugly. Afternoon settles a bit with a 9 mph cross-breeze, but the swell’s still rubbish.

Monday the 7th of September is the first faint glimmer. Morning: 3ft from the northeast, 10-second period – that’s a bit more organised, a groundswell. Wind is 9 mph from the north-northwest, cross-offshore, and the conditions are clean. The combined energy is 158 (moderate). It’s not big, but it’s the cleanest we’ve seen. The standout is Monday afternoon: 2ft from the northeast, 9-second period, with a light 6 mph offshore wind from the west and glassy water. The energy drops to 96 (weak energy), but this is as good as it gets. It’s a beginner-friendly wave, small, clean, and the crowds are only sometimes. That’s your pick.

After that, it’s a long, sad slide. Tuesday the 8th through to the end of the window is a desert of tiny, weak, or onshore junk. Tuesday morning has 1ft from the east-northeast, 9-second period, but the wind is cross and light. Tuesday afternoon is 1.0ft with a 14 (weak energy). Wednesday the 9th is a joke – 0.7ft in the morning, 0.3ft in the afternoon, with strong cross-offshore winds. Thursday the 10th has a brief offshore pulse of 3ft from the south, 8-second period, but the energy is weak (84). Friday the 11th has a 3ft from the north-northeast, 6-second period, and a clean cross-off breeze, but it’s short-period slop. Saturday the 12th is tiny again. The rest of the days are just a blur of 0.7ft to 3ft, mostly from the east or northeast, with periods that are short or long but nothin’ combin’ with good wind. The kicker: Saturday the 19th of September has 3ft from the northeast, 5-second period, with a 19 mph cross-breeze – it’s a messy, lumpy mess.

Honestly, mate, this is a barren run. The one and only chance to get a clean, small wave is Monday afternoon the 7th. After that, it’s a stretch of 13 days with no real quality. The consistent break is Coastguard Beach, but it just ain’t deliverin’ this time. For a kite surfer, the stronger winds and small, weak swell might look interesting, but for a paddle surfer, it’s a hard pass. Forecasts can change, but right now, it’s a long wait for a tiny window.

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.
