The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles.
The first week is a quiet one. From Friday 7th August through to Thursday 13th August, the surf is small and weak. The energy is low, and the waves are mostly under 3ft. It’s not worth rushing out for.
The real action starts on Thursday 13th August. The wind swings offshore from the SW, and the swell pumps up. In the morning, we’re looking at 7ft from the S, with energy hitting 705. By the afternoon, the energy rockets to 1204, and the swell is 8ft. The direction is S, and the reef at Shark Island (Cronulla) is built for a SSE swell. The direction is a bit off, but the power is massive. This is a big wave for experts only. The wind is clean, cross-off from the south, so the faces will be smooth. The water temp is about normal for this time of year, nothing wild.
Friday 14th August is the next standout. The morning has 6ft of S swell, energy at 832, and a gentle cross-off wind from the WSW. The period is 11 seconds, so it’s a proper groundswell. It’s still a big wave, but cleaner than the day before. The afternoon sees the swell drop to 5ft and shift to SSE, with a stronger breeze, so the morning is the session.
After that, the swell fades out. From Saturday 15th August onwards, it’s small and messy. The waves drop below 3ft, the energy is weak, and the wind is mostly onshore or cross-shore. There’s a little bump on Friday 21st August with a 6ft S swell in the afternoon, but the period is short at 6 seconds and the wind is cross-on. It’s not worth the drive.
So, the session to chase is Thursday 13th August. The energy is huge, the wind is clean, and the reef will handle it. It’s a serious wave, so if you’re not a seasoned charger, stay on the beach. Crowds are possible, but not guaranteed.
Rusty.
