The Lowdown

Alright folks, Rusty here. Let’s break down what’s coming our way.

We’ve got a solid run of surf on the cards, starting this Sunday morning and rolling right through the next couple of weeks. The overall pattern is one of consistent, moderate-to-strong SSW groundswell, with a lot of clean windows thanks to light winds. It’s not a wild, epic swell train, but it’s a steady one with a few standout sessions.

The main break in focus is Downtowns, a fairly consistent reef setup that’s fairly exposed to the swell. The water temp is 80°, right on the money for this time of year, so no surprises there.

Sunday morning (August 9) kicks things off with a solid 7ft SSW groundswell, with a very long period of 16 seconds. The wind is a light SSE cross-off, keeping things clean. This is for the experienced crew – that size and period on a reef will have some push. The combined energy is strong at 2330.

Monday afternoon (August 10) sees a bump up in size to 10ft from the SSW, period 18 seconds. That’s big, expert-only territory. The wind is light cross-shore, so it’s manageable but not perfect. Energy is strong at 4951.

The real standout here, though, is Wednesday afternoon (August 19). We’ve got another 10ft SW groundswell, period 17 seconds, but this time the wind goes clean offshore from the ESE at 9 mph. That’s a proper session for the advanced surfer. Energy is pumping at 4581. Mark that one in the calendar.

Another glassy gem shows up on Sunday afternoon (August 16). The swell drops to a more manageable 7ft from the SSW, but the wind goes glassy. It’s clean as a whistle. Great window for the advanced crew.

Through the second week, the swell stays in the 5ft to 8ft range, mostly from the SSW. A few more glassy moments pop up on the 22nd and 23rd of August, which will be worth a look for clean, fun waves.

One thing to keep in mind – those long period swells (over 15 seconds) can make the waves at a reef like Downtowns a bit straight and fast. But with the right wind, it’s a proper wave.

So, bottom line: the best of the best is Wednesday afternoon, August 19 at Downtowns. Get it while it’s clean and offshore. Second pick is the glassy Sunday on the 16th.

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. If you surf the same spot (Downtowns) 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 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.
