The Lowdown
Alright, let’s get into it.
The next couple of weeks are a real mixed bag for the Castlepoint region. We’ve got The Gap (Castlepoint) as our main focus, and it’s a spot that’s pretty sheltered, so it picks up the S and SSE swells okay. The water temp is sitting at 53°F, which is about normal for this time of year.
The surf kicks off this Friday morning, the 7th. We’ve got a solid 6ft of south swell rolling in with a 15-second period. The wind is light offshore from the WNW, so it’s going to be clean. The energy is strong, with a combined reading of 2000, and it's a proper groundswell. This is a good one for experienced surfers; the size and power are there, but it's not for the faint of heart. The afternoon bumps up to 7ft but keeps that clean offshore wind, so it’s still good.
Saturday the 8th is okay, but a step down. Swell drops to 6ft in the morning with a moderate offshore, but the period drops to 12 seconds. It’s clean, but not as exciting. The afternoon is smaller again at 5ft with a lighter cross-offshore breeze.
Sunday the 9th, we’re getting smaller again, down to 4ft in the morning. The wind goes cross-off, which isn't ideal. It’s marginal at best.
Monday the 10th, the surf is pretty poor. Small and ordinary conditions, not worth getting too excited about.
Tuesday the 11th, the swell bumps back up to 5ft with a 9-second period. The morning looks clean with a slight cross-offshore wind, making it a decent option. The afternoon gets a bit messier with a cross-onshore breeze.
From Wednesday the 12th through Thursday the 21st, things get messy. There's some swell, but the wind is all over the place, mostly cross or cross-onshore, and we get some rain. The energy is moderate, but the quality drops off hard.
Now, let’s talk about the standout. Sunday the 16th looks like the pick of the whole run. We’ve got a big 10ft south swell with an 11-second period and a gentle offshore wind. The combined energy is a massive 2532. This is a serious, powerful swell, and it’s only for experts. It’s going to be big, clean, and heavy. The morning is the time to go, as the afternoon wind goes a bit cross-off. This is the one to circle on the calendar.
The following Monday the 17th, that same big swell drops a bit to 8ft, but the wind is onshore and strong, so it’s blown out. No good.
The 19th has some size again in the afternoon with a 10ft swell, but with a cross-off wind at 28 mph, it’s going to be a washing machine. Not a paddle.
The 20th sees even bigger surf at 12ft, but with near gale-force cross-shore winds, it’s a complete write-off.
Then, finally, on Friday the 21st, it cleans up. We’ve got 8ft of south swell with an 11-second period, and a light cross-offshore wind. The energy is strong at 1458. This looks very good. It's not as big as the 16th, but it’ll still be a proper session for those who know what they're doing.
So, to be straight with you: if you’re an experienced surfer, Friday the 7th and especially Sunday the 16th are your days. The 21st is also promising. The rest of the time, it’s a bit average, and there are some big gaps in between. A lot of waiting for the good ones.
