The Lowdown

Alright, folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

Alright, the first thing you need to know is that the start of this period is a bit of a fizzer for the surfer looking for a nice, manageable wave. We’ve got a solid, powerful SSW groundswell on the way, but it's coming in way too big and angry for the first few days, especially at our main spot, Twilight Beach. The water temp is sitting at 61°, which is dead on average for this time of year, so no surprises there.

The real story is that we’ve got a massive pulse of energy hitting the coast on Thursday, 13 August. The combined energy is a massive 6242 (strong to very strong) and the swell is 12 ft from the SSW with a long 16-second period. The trouble is, that’s just too much juice for the break. Wind is light and cross-off in the morning, but the swell is predicted to be too big for this break. The afternoon is the same story – 12 ft and clean onshore wind, but again, too big.

Friday, 14 August, sees the swell drop a touch to 10 ft from the SSW, still with a long 16-second period. The wind is okay, but the forecast is marginal, and the tide is questionable. The combined energy is still very high (5076 in the morning). It’s not the day to go.

Saturday morning, 15 August, is where things get interesting. The swell drops to 7 ft from the SSW, period still a solid 14 seconds. The wind goes offshore from the NNE at 12 mph. This is clean, powerful surf. The combined energy is 1874 (moderate to strong). This is the standout for the first week. It’s a big, powerful groundswell, and it’s at the upper end of what’s manageable for experienced surfers. The offshore wind will make it glassy and clean. Conditions are described as excellent for experienced surfers. It’s a big call, but Saturday morning is the one to aim for. The afternoon drops a bit to 7 ft, but the wind swings cross, so it’s not as clean.

Sunday, 16 August, is a bit of a letdown. The swell is smaller, but the wind is messy, and the marginal forecast means you’re better off giving it a miss.

Monday, 17 August, is a mixed bag. The morning has a strong offshore wind (22 mph from the north) and 6 ft of swell with a very long 19-second period. This is a proper groundswell, but the wind is fresh and a bit gusty. The afternoon is much better: 6 ft, 18-second period, and a clean offshore wind from the NNW. The combined energy is 2287 (strong). This is another good window for experienced surfers who want a long-period wave. The long period (over 15 seconds) means it’s best suited to point breaks or reefs, as it can break too straight at a beach break.

We hit a rough patch from Tuesday, 18 August, through to Saturday, 22 August. The wind turns onshore and the swell gets messy and lumpy. There are a few days of poor surf conditions, with winds from the SW and cross-onshore, making the surf choppy and unappealing. The combined energy on Tuesday morning is 7629, but it’s all blown out.

Things start to get back on track on Sunday, 23 August. The wind is offshore again from the NNW at 12 mph, with 7 ft of 15-second SSW swell. The combined energy is 1857. This is another clean, powerful session for those who know what they’re doing. The afternoon is also good with a gentle offshore breeze.

Monday, 24 August, is a bit of a wildcard. The swell is 8 ft from the SW with a 14-second period. The wind is cross-off in the morning, and the combined energy is 3077. It’s a heavy day, but it's clean. The afternoon has onshore wind, so make the morning call.

The final week starts to look like a write-off. Tuesday, 25 August, brings a massive swell again (12 ft from the SSW, 17-second period) with strong onshore winds. The combined energy is a whopping 10472. This is a full-on stormy mess. Not for us.

The final few days, from Wednesday, 26 August, to Friday, 28 August, see the swell drop off, but the wind is still a problem. The energy is weaker (792 on Thursday morning), so it’s not a great finish.

Bottom line: The best of the best is Saturday morning, 15 August. The second best window is Monday afternoon, 17 August, and Sunday, 23 August is also a solid session. If you’re not an expert, wait for the smaller days late in the second week, but the wind is a gamble.

Rusty.

Information about the Twilight Beach Surf forecast

The above surf forecast table for Twilight Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Twilight Beach can be found by selecting the local surf guide option on the grey menu. Our Twilight 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 (Twilight 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 Twilight 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.
