The Lowdown

Alright crew, Rusty here. Let’s break down the next couple of weeks for Coastguard Beach.

Honestly, it’s a grim outlook. Over the full 16 days, there’s hardly a single session worth getting wet for. The first hint of a wave is on Thursday, September 10th, but it’s a tough one.

So, Thursday morning brings a 4ft swell from the SSW, but it’s a short-period 7-second wind swell with a weak combined energy of 142. The wind is a cross-offshore from the WSW at 19 mph, which will keep it somewhat smooth, but it’s poor quality. By Thursday afternoon, the wind turns offshore at 9 mph, but the swell just drops to 1ft. Not worth the effort.

The rest of the first week is a total dud. Friday and Saturday are glassy flat, just 0.3ft to 0.7ft of nothing. There’s a bit of activity on Sunday with a 3ft south swell, but it’s a 4-second period – that’s just wind chop – and the wind is a messy cross-shore at 22 mph. The combined energy is only 30, so it’s just a bumpy, choppy mess.

We don’t see any real juice until the following Thursday, September 17th, when a 4ft swell from the NNE shows up with a 5-second period. The energy hits 107, so there’s some moderate power, but the wind is a fresh cross-onshore at 19 mph from the NE. That’s going to be lumpy and wind-affected. Not a good call.

The last glimmer is on Saturday, September 19th, with the biggest swell of the run at 5ft from the NNE. The combined energy is 158, so it’s got some weight, but the period is only 6 seconds and the wind is light onshore from the east. That’s a recipe for a messy, onshore close-out.

The water temp is 66°F, which is about average for the time of year, but that doesn’t help when the waves are junk.

This is a tough stretch where the swell and wind just never line up. The breaks are consistent, but the conditions are against us. It’s a rare blank run, but it happens. I’d say the kite surfers might get a better look on the 17th and 19th than anyone with a paddle.

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.
