Costellos Surf Forecast and Surf Report

Alright, let's talk real talk about the next stretch. It's gonna be a rough one, that's for sure. We're looking at a long, frustrating patch with barely a wave worth paddling for. The swell just isn't there, and when there is a little push, the wind is usually messing it up. So, don't get your hopes up for any quick fixes.

The next week and a half is pretty bleak. From the 16th through to the 21st, we’ve got nothing but tiny, weak surf ranging from 1ft to 2ft at Costellos. The energy in the water is mostly weak, with combined energy values between 31 and 105. On the 18th, there’s a slight pulse of energy registering at 105, but it’s all cross-onshore and choppy. Honestly, it’s more of a frustrating tease than anything else. You’d be fighting bumpy, unorganized water for scraps. Even the clean window on the morning of the 19th with some light offshore wind only delivers a weak 2ft wave, and it’s just not enough to be worth the effort. It’s all cross-shore and messy. A long week of no real options.

We finally see a bit of a change around the 22nd and into the 23rd. The swell picks up marginally to around 3ft, and the energy numbers are in the moderate range, with values like 103 and 131 on the afternoon of the 22nd. But the wind is still cross-onshore and creating a fair amount of chop, so it’s still not going to be any good. This is the same story we’ve been seeing, just a little bigger. Not worth getting changed for.

Then we hit another flat spell from the 24th to the 25th, with waves dropping back down to a dribbly 1ft. There is a clean window on the 24th with a cross-offshore breeze, but with that little swell, it’s a still, glassy lake, not a surfable wave.

Looking into the final week, things start to get a little more interesting, but it’s far from a sure thing. On the afternoon of the 26th, we see the most notable uptick in energy for the whole period, with a combined energy of 137. We’ve got a moderate offshore wind and the surf is 1ft but with a long 15-second period. That’s very long-period groundswell. Even though it’s small, this could be a standout moment. This is about a week away, so take it as promising, but not guaranteed. A long-period swell like this can be an absolute gem at a reef like Costellos, especially with offshore winds. That’s the one to keep an eye on. The energy stays in the moderate range (185) on the 27th, but the wind is cross-onshore, spoiling it.

After that, we go back to the same old story. The winds are mostly cross-shore or cross-onshore, and the swells are weak and short-period. The last day of the finder is on the 31st, with 3ft of cross-shore slop and 89 energy. Blah.

So, there’s your best bet: the afternoon of the 26th of August. It’s not perfect, but it’s the only real sign of life. Everything else is a waiting game. A long, dull one. Keep the board waxed, but maybe don’t bother with the wetsuit for a while.
