Alright, let’s get into it. Rusty here.
First up, Sixtynine. To be straight with you, the next week-and-a-bit is pretty slim pickings. We’re looking at a long, quiet stretch starting now, with no real surf to speak of from Saturday, July 11th right through until the middle of the following week. The first few days are flat or near-flat, with tiny 1ft to 2ft swell and cross-shore winds. Not worth paddling out for.
We start to see a little pulse building from Tuesday, July 14th. The swell climbs to 2ft to 2ft from the west, with a period around 16-19 seconds. That’s a decent long-period groundswell. Combined wave energy hits moderate levels (251 to 267). The problem is the wind is onshore, which will mess up the face. Wednesday, July 15th is similar, 3ft west swell, period around 15-16 seconds, energy in the 300s, but again, onshore or cross-onshore wind and some rain showers. Not clean.
The first real standout arrives on Thursday, July 16th. Morning and afternoon both have 3ft west swell, period 15 seconds, and glassy conditions. That’s the best we’ve seen. Combined energy is 301. Expect good surf conditions. This is a clean, long-period west swell, which at a spot like Sixtynine—intermediate-level, consistent, and fairly exposed to the west—will offer decent little waves. The optimum swell direction is from the west-northwest, and the swell is coming from the west, so it’s a good match. It’s not big, but it’s clean and rideable. Keep in mind, with a 15-second period the waves will have some punch and longer gaps between sets. Crowds here are listed as “sometimes,” so you might get a few out, but nothing crazy.
Friday, July 17th is still rideable with 2ft to 2ft west swell, but conditions are more ordinary. Glassy periods in the afternoon though.
From Saturday, July 18th onward, the swell fades fast. We drop back to 2ft and below, and by Monday, July 20th it’s basically flat again. There’s a gap of several days with no surf worth chasing. A tiny 1ft southwest groundswell shows up on July 24th and 25th, but it’s small, weak, and poorly directed. Not worth the effort.
So, the highlight here is Thursday, July 16th. Sixtynine, glassy, 3ft west swell, 15-second period, clean and surfable.
Rusty.

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.
