The Lowdown
Alright, Rusty here. Let's talk about the next couple of weeks for your local spot.
We've got a solid run of surf coming up, but the standout window is definitely later this week. The water is sitting at 66°, which is a touch warmer than usual for this time of year, so you might get away with a slightly thinner wetsuit, or maybe just a spring suit.
The first few days are modest. Wednesday afternoon, the 26th, kicks things off with some clean, cross-off waves from El Olon de Ilo. It's a tricky reef break that's pretty inconsistent, so don't expect a party. The swell is a small 3ft from the SSW, with a moderate energy reading of 371. It's a gentle start.
Thursday the 27th looks similar, with smaller 2ft swell from the SW. The morning is clean with a light cross-off breeze, but the afternoon gets a little cross and messy. Not a day to get too excited about.
Now, Friday the 28th is the main event. This is where it gets good. We've got a proper SW groundswell pushing in, with a very long 16-second period. The wave energy is massive, hitting 2574. The swell is 8ft in the morning, bumping up to 8ft in the afternoon. With that size and power, this is strictly for experienced surfers only. The winds are light and cross-off, keeping it clean. The direction is a solid match for the break's optimum S exposure. This is a classic, powerful reef setup that will handle that long-period energy well. Saturday morning, the 29th, will still have plenty of punch with 7ft swell and 14-second period, but the afternoon gets a bit more cross and the energy drops a touch.
The following week runs from Sunday the 30th through to the end of the period, with a steady, fun-sized swell. It drops from 6ft on Sunday morning down to around 5ft to 3ft for most of the following week. The period stays solid, often in the 12-19 second range, which is great for a point break or reef. The wind is mostly light and cross-off, keeping things clean. Tuesday the 1st of September and Wednesday the 2nd have some nice clean morning windows, but the afternoons get a little crossed out. The standout in the second week is Monday the 7th of September afternoon, where the wind goes completely glassy with a 3ft, 18-second SW groundswell. That's a dreamy window for a more relaxed session. The energy on that one is 1264, a solid moderate push.
Overall, Friday the 28th is the absolute top pick for the big, powerful, clean groundswell. If you're after something a bit more manageable but still excellent, the mornings of Sunday the 30th and the glassy afternoon of Monday the 7th are your best bets.
Rusty.
