Costellos Surf Forecast and Surf Report

Listen up, crew, it's Rusty. We're taking a hard look at sixteen days up at Costellos, and the story is mostly about patience. This is a reef break that's known for being inconsistent, so you can't just roll up and expect perfection.

Right now, it's dead flat. Wednesday the 9th, Thursday the 10th, all the way through the start, it's poor conditions with next to no energy. The combined swell energy is stuck in the teens and twenties, which is weaker than weak. You're looking at tiny, unrideable lumps.

We get a tiny tease on the morning of Thursday the 10th. A 3ft south swell with a clean, moderate offshore breeze from the West. The period is only 6 seconds though, and the energy is weak (89). It's surfable waves, but very ordinary. That's the best we've got for the first week, and it's not saying much.

After that, we hit a grinder. Days and days of frustratingly small surf – mostly around 1ft to 2ft – with short periods. The wind is often clean or cross-offshore, which is a killer combo for a wave that just isn't there. The energy readings sit in the 30s and 40s; the ocean just doesn't have the power for the reef to do its thing. It's a blank run that's pretty normal for a spot that doesn't break often.

Now, there's one day that has my attention. The real standout is Thursday the 24th of September. The morning forecast is glassy – zero wind, calm as a lake. That is a massive, massive win. We get the biggest wave of the forecast, a 5ft northeast swell, with a combined energy reading of 269. That's finally some moderate power in the water. The period is short at 8 seconds, so it's a local wind swell, but for an inconsistent spot like this, that's a real pulse of energy. You'll have clean, glassy conditions with some proper size to work with.

This spot gets "often" crowded, so expect a full lineup when that glassy swell hits on the 24th. The swell is coming from the NE, not its optimum SE direction, but the quality from the glass-off and the size will make up for it. It's the only call in the whole window, and it's a long way out, so keep your fingers crossed. The water temp is about normal for this time of year, nothing wild.

Rusty.
