The Lowdown
Alright, this is Rusty. Let's look at what's coming down the pike for the next couple of weeks.
Right off the bat, we’ve got a solid run of surf on the cards, but it’s not all smooth sailing. The standout period is undoubtedly around August 10th. Monday morning is looking absolutely prime – we’ve got a clean 5ft SSW groundswell with a very long 19-second period pushing in. The wind is a light cross-offshore breeze, making for some super clean conditions. This is a proper advanced wave at Yo Yo's-The Wedge, so it’s not for the faint of heart, but if you've got the skills, Monday morning is the session to point for.
The swell energy is cranked up for a lot of this period, with combined energy readings in the thousands, hitting over 4900 on Monday afternoon. That’s some serious power. From Tuesday the 11th through the 13th, we’re seeing swell heights consistently over 7ft, often up to 8 to 10ft, with periods around 16 to 17 seconds. The winds are mostly cross-off or cross, keeping things reasonably clean despite the size. However, with waves over 8ft, this is strictly for experts only. The water temp is about average for this time of year, nothing unusual to report there.
Mid-week, from the 14th to the 16th, the swell drops back a touch to the 7 to 7ft range, but the quality remains marginal according to the models, with consistent cross-off winds. It’s rideable but not the pick of the fortnight.
The second week, from August 18th onward, we see a new pulse of SW groundswell filling in. The 19th and 20th look promising with 8ft SW swell, again with decent 16 to 18-second periods. Winds are cross-offshore, so it should be clean. The energy is still strong, hitting 3670 on the Thursday morning. A notable spot is on August 23rd – Sunday afternoon – where the swell drops to 5ft but the conditions are described as excellent for experienced surfers, with clean lines and light winds. That could be a real sleeper session a full two weeks out, but obviously, that’s a long-range call and less certain.
Overall, the surf window is pretty much open for the whole 16 days, but the real standout is Monday, August 10th. Don’t sleep on it.
Rusty.
