The Lowdown

Alright folks, Rusty here with a look at the 16-day forecast for our stretch of coast. To be honest, it's a pretty bleak run of surf. The only break showing any real potential is Coastguard Beach, but even then, it's a long wait for anything worthwhile.

The water temperature is sitting at 69°, which is about 2° warmer than usual for this time of year, so nothing crazy there, just a touch on the mild side.

We've got a big gap of very poor surf stretching from now all the way through the end of August and into the first few days of September. The first recommendation doesn't pop up until Friday, September 4th, when a pulse of moderate energy (391) arrives. That morning, Coastguard Beach will see a northeast swell of 6 ft with a 7-second period. The wind will be a cross-onshore from the southeast at 12 mph, making for a choppy and messy lineup. It's not great. That afternoon, the wind swings south and picks up to 22 mph, with heavy rain, making conditions even worse. The swell drops to 5 ft from the northeast, with a combined energy of 323, but it's going to be lumpy and cross-shore.

Saturday, September 5th, offers a bit of a silver lining. The swell is still there, but it's dropping. The morning sees a 4 ft swell from the east-northeast with a 9-second period, and the wind is a strong cross-offshore from the north-northwest at 40 mph. This will clean up the surface, but those gale-force winds are going to make it a real battle to get out. The combined energy is moderate at 185. The afternoon sees lighter conditions, with the wind backing off to 37 mph from the same direction, and the swell dropping to 3 ft (energy 141). It's clean, but the wind is still a major factor.

Beyond that, the surf fades away again. The only other standout is Thursday, September 10th, in the afternoon. The swell is tiny at 3 ft from the east-southeast with a 5-second period, so it's a weak, short-period windswell. But the wind turns offshore from the west-northwest at 9 mph, making for clean, glassy conditions. The combined energy is low at 45. It's the most surfable window in the whole run, but still only for the most patient.

The short answer is: don't get your hopes up. This is a long, quiet stretch. For kite surfers, the strong winds on September 5th might be a better option than 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.
