The Lowdown
Alright, Rusty here. Let’s take a look at what this stretch has got in store for you.
It’s a bit of a mixed bag, to be honest. There’s swell on the way, but the quality isn’t always there. The first part of the week is a bit of a tease, with Monday mostly looking like a write-off, but things start to tidy up from Tuesday.
Yo Yo's-The Wedge (a reef break) is the only spot on the menu, and it’s for advanced crew only. The water temp is about average for the time of year, so wetsuit choice is standard.
Monday 17 August is a no-go. You’ve got 5ft to 5ft SSW swell, a 14-second period, but it’s coming with cross-shore wind and the conditions are just marginal. Wave energy is moderate (985 and 836). Don’t bother.
Tuesday 18 August morning is the standout of the week. It’s glassy – dead flat wind from SSE at just 3 mph – clean as a whistle. Swell is 4ft from SSW with a long 16-second period. The combined energy is strong (1961). This is the call for experienced surfers looking for a clean session.
Wednesday 19 August ramps up to 8ft to 8ft SW swell with an 18-second period. That’s proper groundswell, and it’s big – expert territory. The morning is cross-shore, but the afternoon is clean. Energy is very high (3608 / 4078). With that size and a long period, The Wedge could be a freight train. Crowds are often here, so expect company.
Thursday 20 August morning keeps the 8ft SW swell with a 16-second period and sideshore winds, but the conditions are excellent for experienced surfers. Energy is still strong (3723). This is the other real highlight before things start to drop.
From Friday 21 August through to the end of the month, the swell bounces between 3ft and 8ft, but the wind stays mostly cross-off or cross-shore. The energy drops from strong to moderate (around 600 to 2600). The sessions are mostly described as marginal, with a few clean windows. The long-period swells (15-19 seconds) will hold some shape, but the consistency and wind aren’t doing you any favours.
Friday 28 August sees a lift back to 8ft SSW swell, but the cross-shore wind brings a chop. It’s not clean.
The final days of August and into 1 September are more of the same: moderate swell, side winds, and nothing that screams priority.
Best on offer: Tuesday 18 August morning for the glassy, clean 4ft SSW groundswell. If you want size and power, Thursday 20 August morning is the call, but be ready for the crowd and the challenge.
Rusty.
