G’day, I’m Rusty. Let’s have a look at what’s on the table for Castlepoint – The Gap over the next couple of weeks. It’s a fairly sheltered little nook, so it needs the right angle to fire, and for the first few days, that’s just not happening properly.
The first recommendation actually comes in on Friday 3rd July morning, but the surf is poor. You’re looking at 1.2m from the east with a 10-second period, and a combined energy that’s barely shrugging its shoulders (351). The wind is a cross-off from the northwest at 20 km/h, which keeps things looking clean, but the wave quality is just not there. Not worth suiting up for.
The whole weekend stays ordinary. Saturday pumps in a little more east swell at 1.4m, but the cross-wind on Saturday afternoon turns it into a chop-fest. Sunday’s a write-off too, with a weak 0.9m east pulse and "very ordinary" conditions. By Monday, an east-northeasterly swell jumps to 3.0m on Monday afternoon – that’s heavy, well over 2.5m, so only for experts – but the wind is all wrong, cross-onshore and messy, so it’s blown-out chaos. The combined energy on that one hits 2202, so there’s plenty of power, but the wind ruins it.
Now, Tuesday 7th July morning – that’s the first real standout. A clean 1.8m south swell, 10-second period, with light west-southwest winds (10 km/h) blowing cross-off, keeps the surface glassy. The energy reading is 1121 – moderate, but solid enough to push through. The water temperature is 55°F, which is about normal for this time of year, so no surprises there. This is the pick of the early window; good for intermediates, clean, and decent shape. That south direction isn’t perfect for the optimum east-southeast direction, but it’s far from useless here.
Tuesday afternoon gets a bit too chunky and cross-choppy, and Wednesday and Thursday are ruled out by strong onshore winds and lumpy seas. From Saturday 11th through Tuesday 14th morning, there’s a real gap – nothing worth paddling out for. The swell sticks around, but the wind is always putting a chop on it.
Then Monday 13th July blasts back. This is the big one. Monday morning brings a 3.0m south groundswell rolling in at 11 seconds, with a light 10 km/h offshore wind from the west-northwest. That’s clean, powerful, and perfect for experienced surfers – combined energy is 2137, strong and meaty. The 10-second period is respectable, long enough to hold shape, and with offshore wind, expect groomed lines. Monday afternoon stays excellent, dipping to a gentle offshore from the west at 15 km/h, energy hitting 2734, still at 3.0m. This is the standout of the entire outlook – for experts only due to the size, but if you’ve got the nerve, it’s go time.
Tuesday 14th afternoon offers a more manageable 2.1m from the east-southeast at 11 seconds with a light southwesterly breeze – clean and very good quality. Wednesday 15th morning is another cracker: 2.5m east-southeast swell, 12-second period, and a clean offshore from the northwest at 25 km/h. That’s a proper groundswell, best on the reefs and points around here, not so much for the beach breaks where it might run too straight. After that, the wind picks up and the quality drops off through the end of the period.
If I had to name the two best windows: Tuesday 7th morning for a fun, clean, mid-sized session, and Monday 13th for those who want big, clean, powerful waves. Get on it.
Rusty.
