The Lowdown

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

The first real surf action kicks off Saturday morning, 5th September, at Watermans. This is a reef break, and it’s a fairly consistent spot, but it’s a beginner-friendly wave. The early call is for a solid 8ft swell out of the WSW, which is the sweet spot direction for this place. The period is a nice 14 seconds, so there’s some proper groundswell energy in the water. The combined energy reading is a strong 2749, so there’s plenty of push. The water temp is sitting at 64°, which is about normal for this time of year. The catch? The wind is a stiff 16 mph cross-shore from the north, so it’s going to be a bit messy with a cross-chop. It’s surfable if you’re keen, but it’s not the best of the run.

Sunday the 6th looks a bit cleaner. The swell holds around 8ft to 8ft from the same WSW direction, with a 13-second period. The wind swings around to the SSE and SE, giving us a cross-off breeze, which cleans things up nicely. The combined energy is still strong at 2415 to 2567. This is a solid session for the experienced ones, but the marginal tide comments suggest you need to pick your time.

The real standout of the first week is Monday, 7th September. Morning session is the pick. The swell is 8ft from the WSW, with a 17-second period creeping in. That’s a long-period groundswell that will wrap nicely into the reef. The combined energy is a massive 3726. The wind is a light 9 mph from the SE, making it a clean cross-off all morning. This is excellent surf for experienced surfers. The afternoon is still good, but the wind picks up a bit. This is the best on offer in the first week.

Tuesday the 8th is also a ripper. The morning shows an 8ft swell, 17-second period, and the wind is offshore from the ESE at 16 mph. That’s clean, offshore, and powerful. The combined energy is 3700. This is a serious session for the crew who know what they’re doing.

The second week has some promise. The swell drops a little from the 10th onwards, but it holds around 4ft to 5ft with a 14-15 second period. The wind is lighter, which is nice, but the wave quality is a bit more marginal. The real highlight of the second week is Monday, 14th September. The swell jumps back up to a solid 10ft from the WSW, with a 14-second period. The wind is a light 9 mph from the SSE, giving a clean cross-off. The combined energy is a whopping 3599. This is another excellent session for the experienced surfers.

Then, looking further out, the 19th and 20th of September have a massive pulse. The swell hits 12ft to 13ft from the WSW, with periods of 17-19 seconds. The combined energy goes through the roof, hitting 7487 up to 10151. That’s very strong wave energy. The problem is the wind is onshore from the west, which will chop it up. This is more of a spectacle than a good paddle, and honestly, it might be more interesting for the kite crew than us surfers.

Overall, the standout days are Monday the 7th and Tuesday the 8th for the first week, and then Monday the 14th for the second week. The long-range weekend of the 19th and 20th is huge but messy. Keep an eye on the wind.

Rusty.

Information about the Watermans Surf forecast

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