The Lowdown

Alright, I'm looking at the finder data here, and let me tell you, it's a tough stretch for the local surf. We've got a 16-day window starting now, and the first slot that offers anything at all is Tuesday morning, September 8th. But even then, it's a grim picture.

The overall pattern is flat, flat, flat. For the entire 16-day run, the biggest wave height we see is a paltry 4 ft, and that's on Tuesday, September 15th. The combined energy of all swells directed here is weak, barely cracking triple digits just once, at 92 on that same day, which is still feeble. Most of the time we're looking at energy values of 8, 5, or 3, which is pretty much nothing. The swell direction is all over the shop – ENE, S, E, SSE – but it doesn't matter because there's hardly any size.

Coastguard Beach is the only break on offer. It's a beginner spot that’s exposed to swell, but with nothing coming in, it's a write-off. The winds are mostly cross, cross-off, or cross-on, and the water temp is about average for this time of year.

Right, let’s walk through it, day by day. Over on Tuesday the 8th, we've got 0.7 ft of swell and a period of 8 to 9 seconds. The wind is offshore in the morning, which would usually be a major positive, but with waves that small, the "clean" conditions just mean you're looking at a lake. The afternoon gets a bit lumpy with cross-onshore. There's no score above zero, and the wave comment says "poor surf conditions" every single time. Wednesday the 9th is worse, with 2 ft to 3 ft but a period of only 4 seconds – that's pure, junk windswell. The rest of the first week is the same story: tiny waves, weak energy, and poor quality.

After the first few days of September, there's a massive gap. From around the 11th all the way through the 15th, the surf doesn't improve. On Tuesday the 15th, we get that 4 ft NE swell, but it's accompanied by an onshore wind, a period of just 6 seconds, and a "poor surf conditions" tag. That's not surfable. It's actually more of a kitesurfing setup than anything a paddle surfer would want.

The second week, from the 15th onwards, is just as bad. Wednesday the 16th has 3 ft and a cleaner cross-off wind, but the energy is still weak at 80, and the period is 7 seconds. You’d be bored in five minutes. The rest of the month is a flat, energy-sapped slog of 0.7 ft to 1 ft waves. There’s not a single standout session in the entire 16-day forecast.

Honestly, if you've got a board, leave it in the car. This is one of those blank runs that's more normal for the area when the pattern is this dead. The forecasts can change, but right now, there’s nothing to ride.

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.
