The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, we’re looking at a solid stretch of surf coming in, but it's not all perfect. The first few days are a bit of a mix. Thursday morning, Yo Yo's-The Wedge is pumping with a 8ft SSW swell packing a serious punch, wave energy is strong at 2961. The wind is cross-off from the SE, keeping things clean, but the water temp is sitting at 80°, which is bang on normal for this time of year. The tide is a bit questionable, though, so it’s not gonna be a total dream. The swell is big, over 8ft, so this is one for the experienced crew only. That deep water reef is a proper beast.
Friday drops a touch, still a solid 7ft from the SSW, but the wind is more cross-shore and you feel that slight chop. Saturday and Sunday are similar – lots of energy in the water, but that cross-shore wind keeps it from being truly glassy. The swell is still big, so it’s advanced territory.
Now, Monday morning the 17th, the swell backs off a bit to 5ft, and the wind is light and cross-off. It’s cleaner, but the energy drops to 987, which is moderate. Tuesday the 18th, the swell direction shifts to the SW, and the energy jumps back up to 1912. The morning looks clean with a light breeze, but it’s a bit smaller at 5ft. The tide is still a factor.
But hold on. Wednesday the 19th is the standout. Morning waves are 8ft from the SW, swell period is a very long 18 seconds, and the wind is a light, cross-off breeze. This is groundswell perfection. The wave energy is massive at 3529. The afternoon is even better – 8ft, 18 seconds, and the energy hits 4074. The wind stays light, the surf is clean. This is a proper session for experienced surfers. The long period means it will be heaving, but it's a reef, so it should handle that energy beautifully. Just be aware, crowds are often an issue here, so get in early.
Thursday the 20th, the swell peaks at 10ft in the morning. That’s a massive wave – expert only. The wind is a moderate cross-off, so it’s clean, but the period drops to 16 seconds. Still a lot of power there (4039 energy). The afternoon is a bit smaller at 8ft.
The rest of the window settles into a consistent pattern. From the 21st to the 28th, we’re seeing a steady run of SW swells, mostly in the 5ft to 8ft range. The wind is almost always cross-off from the SE, keeping things clean. The energy levels are moderate to strong, mostly in the 1,000 to 2,900 range. The 24th of August (Monday morning) is a nice little pick-up with 6ft, clean conditions, and a solid 14-second period – a good session for the more experienced intermediate who can handle a reef. Later in the window, the 27th has a 7ft SW swell with clean conditions, but the energy is strong.
Overall, the first week has some size and punch, but the wind is the main factor. The absolute best is that Wednesday the 19th with the long period groundswell and light winds. Get on it.
