Table - best surf conditions forecast for Castlepoint - The Gap over the next 16 days.
Righto, let's talk about what we've got on the menu at Castlepoint – The Gap. It's a bit of a slow burner this forecast period, so don't go getting your hopes up for the next few days.
The week starts off pretty grim. Friday and Saturday, the 10th and 11th of July, are a write-off. The swell is there, but it's all onshore and lumpy. That 10ft on Friday morning might sound big, but with a fresh southerly blasting across it, it's just a washing machine. Honestly, the conditions are so poor you wouldn't bother paddling out.
We do get a glimmer of hope on Sunday morning, the 12th. The wind swings around to a light WNW offshore, and the water will be clean. The swell is small, only 3ft, but it's a long-period 13-second groundswell from the SSW. This spot is sheltered, so the energy is weak, but those long lines should wrap in with a nice shape. It'll be tiny, but for a beginner-friendly break that's fairly consistent, it's the best we've seen for a few days. The water temp is sitting at 55°, which is about normal for this time of year.
After that, we hit a real flat spell. From Monday the 13th right through to around Wednesday the 22nd, it's a whole lot of nothing. Days and days of tiny waves and unappealing winds. There are a few mornings where the wind goes offshore, but the swell is so weak it's barely dribbling. You'll be sitting on your board a lot.
The next real talking point doesn't come until the end of the month, which is more than a week away. Wednesday the 22nd of July kicks off with a pulse of SSW swell, hitting 6ft with a solid 14-second period. The combined energy is strong, but the wind is a gentle onshore, which puts a bit of a chop on it. It's marginal, but it's the most interesting thing we've seen in a long time.
Then, hold onto your board for Saturday the 25th of July. The afternoon session looks like the true standout. The wind drops to a light northerly, going cross-offshore, and the sea should clean right up. The swell is a consistent 6ft from the ENE with a 10-second period. The energy is moderate, and the forecast says "expect good surf conditions." That's the pick of the entire 16-day window. With the wind easing off, it's going to be the cleanest and punchiest day on offer, though keep in mind it's a long way out, so treat it as a promising prospect rather than a guaranteed bet.
Alright, stay stoked, check the cams, and I'll see you out there.
