Castles Surf Forecast and Surf Report

Alright, let’s get down to it. Rusty here with the long-range report. I’ll be straight with you: the next few days are not exactly firing. We’re starting slow, so don't be in a rush to get wet on Saturday. There’s a weak 4ft SW swell at Castles (Big Island) and the water temp is about average for the season, but the conditions are looking marginal. It’s going to be a scratchy, messy couple of days with the wind all over the place. There’s a tiny window Monday morning where the wind lays down, but the swell drops to just 3ft, so it’s not worth getting excited about.

We get a little more energy moving through the middle of the week, with the swell picking up to around 5ft to 6ft on Wednesday, and the cross-off winds will keep things clean enough. It’s an improvement, but still not the main event. This stretch is all about finding a decent bank and making the most of it.

Then we hit a bit of a lull. The weekend looks pretty poor with small surf and strong winds, so if you’re not keen on a fight, stay home. Now, the good stuff. The real promise starts to show around Tuesday the 22nd. The swell is on the rise, hitting 7ft from the SW, and you can feel the energy building. The next morning, Wednesday the 23rd, is the money window. We see 4ft of SW swell, but the breeze turns offshore from the ENE. That’s a recipe for perfection at this spot, giving us what looks like very good surf. This is the one to plan for.

Looking further out, there’s some serious size coming in the following week, but it’s a double-edged sword. We’re talking solid 8ft to 8ft SW swells with some very long-period energy, especially on Thursday the 24th and Sunday the 27th. That’s big, expert-only territory, and the wind looks like it’ll be switching onshore, making things lumpy and tough. There’s potential for a big swell, but it might be better to watch from the cliff than be in the water. The long period might also make it break too straight on the beach breaks, so the reef at Castles could be the only place that handles it.

So the game plan is simple. Don’t waste your energy on the small, choppy days. Be ready for that Wednesday morning session; it’s the standout. And keep an eye on that bigger swell later, but be prepared for a battle with the elements.

Rusty, signing off.
