The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up on the surf front. I gotta be straight with you – it’s a tough stretch. The next week and a half are looking pretty grim, with a real dry spell of no surf on offer from now all the way through to the end of July. We’re talking a solid gap of about 10 days of nothing worth paddling for. The water temp is sitting at 80°F which is pretty much normal for this time of year, so at least a dip won’t be a shock to the system.

The first chance of anything rideable shows up on the afternoon of the 30th of July. It’s only a tiny 1ft southwest swell, but with a very long period of 18 seconds. The wind goes glassy, so conditions will be clean. The combined swell energy is still weak at (49), so it’s not going to be a classic, but it’s a start.

As we roll into early August, things try to pick up a little. On the 2nd of August, the Sunday afternoon session at Sixtynine might be your best bet in the whole 16-day window. We’re looking at a 2ft west swell with a solid 12 second period, and the wind is cross-offshore, keeping it clean. The energy is building to moderate (74), so it’ll be surfable, even if it’s not pumping. The crowd situation at Sixtynine can be busy sometimes, so keep that in mind if you’re after a quiet paddle.

The 3rd of August, Monday afternoon, also has a similar 2ft west swell at 13 seconds with clean cross-offshore wind and moderate energy (92). That’s a close second to the Sunday session. It’s all pretty small stuff though, nothing over 5ft, so it’s fine for all levels. After that, the energy drops back off into weak territory through the rest of the week.

So, the standout is really the afternoon of Sunday the 2nd of August. It’s not a huge swell, but with the clean conditions, some period behind it, and that moderate energy, it’s the best on offer. The rest of the window is a waiting game.

Rusty, signing off.

Information about the Sixtynine Surf forecast

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