The Lowdown
Alright, this is Rusty, and I’m looking at the next sixteen days for our little corner of the wave world. We’ve got a reef break that’s exposed to the west, and it’s looking like a pretty solid run of swell is on the cards.
First up, the standout window. We’ve got a real beauty shaping up for Sunday, September 13th. The early morning is calling for clean, glassy conditions, with a solid 4ft NW groundswell, and the period is a super juicy 13 seconds. That long-period energy is perfect for a reef setup like this, bringing in well-shaped lines with good gaps between sets. The water temp is sitting at 73°, which is over 5° warmer than what’s normal for this time of year – you’re not going to want a thick winter suit for this one. The combined energy is sitting at 545 (moderate wave energy), and it’s got that real punchy feel. This is easily the best bet for the whole run.
After that, the surf stays rideable but the quality drops off a bit through the week. Monday the 14th is still decent in the morning with 4ft NW and a clean offshore E wind. By mid-week, the wind is a bit of a mess, with onshore and cross-shore breezes messing up the face. The swell hangs around but it gets choppy and a bit raw.
Then, a big call-out for Saturday, September 19th. That morning we have an excellent sized 6ft NW groundswell, a very long 13 second period, and glassy conditions. That’s a powerful combination. The combined energy jumps right up to 1136 (strong wave energy). This is only going to be good for experienced surfers, as over 5ft it starts getting a bit heavy for the average punter. If you’re dialled in and hungry, that Saturday morning is the real main event.
The last week of the outlook has waves on offer but nothing that screams epic. The morning of the 24th of September has good potential with 4ft NW and glassy conditions again, another solid 13 second period, and the combined energy is back at 545. That’s a nice way to finish the run. There are a few other mornings with offshore or glassy states, but the size is generally down under 4ft. Overall, the window is pretty consistent, so if you can’t make the standout sessions, there’s still fun to be had, especially on those glassy mornings.
Rusty.
