The Lowdown

Alright folks, Rusty here. Let’s get stuck into what’s cooking for the next couple of weeks.

We’ve got a solid run of swell coming through, with some real gems hidden in the mix. The water is sitting at a warm 79°, which is bang on average for this time of year, so no need to dig out the extra rubber just yet.

First up, the standout action kicks off Tuesday the 8th of September. The swell is a solid 6 ft from the SSW with a long, juicy 18-second period. That’s proper groundswell, meaning plenty of energy and good shape, especially for a reef setup like this. The combined energy is a hefty 3392 (moderate to strong), so you’ll feel the push. The winds are a light SSE breeze in the afternoon, making it clean and offering up excellent conditions for experienced surfers. This is your pick of the early window.

Things stay pumping through Wednesday the 9th, but the wind gets a little more cross, making it a touch messier. The swell bumps up to 8 ft from the SSW, but with the cross-shore, it’s a day for the confident crew. For the average punter, this is getting into the too-big zone.

The real magic starts to show up again on Friday the 11th of September. By the afternoon, the wind swings ESE and goes offshore, cleaning up a 6 ft SW swell with a 16-second period. That light offshore breeze will make for some beautiful, lined-up waves. The energy is still strong at 1919.

Then, hold onto your boards, because Tuesday the 15th of September is looking glassy. First light, the wind is practically non-existent, and the swell is 6 ft from the SW with a 15-second period. The combined energy is 1528, and the report says it’s glassy. That’s as good as it gets. The afternoon stays clean with a cross-off breeze.

Later in the window, Saturday the 19th of September also serves up a glassy afternoon, with a 5 ft SW swell. It’s smaller, but perfect for a cruise.

The real heavy hitter might be Wednesday the 23rd of September. The morning sees an 8 ft SSW swell with a 19-second period and a massive combined energy of 4567. That’s serious power. The wind is light, but cross-onshore, so it’s one for the experts only. The afternoon drops to 7 ft with a 16-second period and 3890 energy, which is still very strong.

The best of the best: Tuesday the 8th of September afternoon is a beauty. But the undeniable standout is Tuesday the 15th of September morning. That glassy, clean 6 ft SW swell with a 15-second period is the dream ticket. Friday the 11th of September afternoon is another top contender with that offshore wind.

So, get your board waxed. The next two weeks have some serious potential, especially for the experienced surfer. Just remember, those bigger days (over 8 ft) are for the hardcore only. And this is a reef break, so watch your fins.

Rusty.

Information about the Downtowns Surf forecast

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

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 Downtowns 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.
