The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the coming weeks at Off The Wall.
We've got a solid run of surf kicking off right away. This is an exposed reef break, so it handles swell well, but it's strictly for advanced crew. The water temp is about average for this time of year, nothing weird going on.
Tuesday, August 11th starts us off with a clean 7ft S swell pushing in from the south. It's got good energy behind it (1816) and the wind is light offshore from the ESE. The sets will have some proper length between them with that 12-second period, making paddling out a bit easier. It's a bit solid for beginners, but for the experienced surfer, it's a beauty. The afternoon eases back a touch to 5ft, still clean with a cross-offshore breeze.
Wednesday, August 12th looks like the first real standout. Morning sees a clean 6ft SW groundswell with a very long 18-second period and a light cross-offshore wind. That's a heap of energy (2763) and those waves will have serious push and shape, especially on a reef. The afternoon stays just as good, glassy offshore wind and the same size with a 17-second period.
Thursday, August 13th gets a bit tricky. The swell jumps to 8ft with a long 18-second period, which is now big and powerful, only for experts. But the wind swings onshore and cross-shore, putting a chop on the surface. Not the one.
Friday, August 14th morning is a bit messy with a cross-onshore wind, but hold onto your board for the afternoon. The wind drops to absolute glass, calm, with a clean 6ft WSW swell. That's a magic window right there.
Saturday, August 15th and Sunday, August 16th keep the good vibes rolling. Saturday afternoon goes glassy again with a clean 6ft swell. Sunday is a full morning of glass with a 5ft WSW swell, and then a clean cross-offshore breeze in the afternoon. Consistent, clean, and manageable size.
Monday, August 17th is another one to skip. Swell hits 8ft, which is expert-only territory, and the wind is onshore and messy.
Now, Tuesday, August 18th is a wild card. The morning is a solid 10ft SW swell, clean with a cross-offshore breeze. That's a big, powerful day for experts only. The afternoon keeps the 10ft size but the wind cranks up to 40 km/h offshore. That's strong offshore and clean, but you'll be fighting to get into anything. Not for the faint of heart.
The following week eases off. Wednesday, August 19th offers a clean 5ft with offshore wind, a nice breather. Thursday and Friday (August 20th & 21st) are pretty poor with onshore winds and small, weak swell. A bit of a flat spell.
Then we get a second, more promising standout for the long range. Saturday, August 22nd morning is glassy with a clean 6ft WSW groundswell, and the afternoon is even better: clean, light offshore wind, and a 6ft WSW swell with a very long 18-second period and a massive 3411 energy reading. That's proper.
Sunday, August 23rd keeps the fire burning. Morning has a clean 8ft swell with a long 15-second period and light offshore winds. This is a big, clean day for the experts, a true standout for the end of the run.
The last few days of the forecast, from Monday, August 24th onwards, fade out again with smaller, weaker swell and onshore winds. Nothing to write home about.
The two true standouts are Wednesday, August 12th with that long-period groundswell and clean wind, and the Saturday/Sunday, August 22nd-23rd window. The latter is further out, so keep an eye on it, but the potential is huge.
Rusty.
