The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s coming up for The Gap at Castlepoint.

The pattern ahead is a slow burn, with the first proper action not firing until late next week, then a ripper of a window after that, but with a few rough edges. The water temp is sitting around 55°, which is just about average for this time of year, nothing to worry about.

From Saturday 25th July afternoon, the surf is poor – 3ft of ENE swell, short period cross-shore wind and moderate rain. Best to stay on the beach that day.

Sunday 26th July morning is the first glimmer of hope, with a clean 7ft S swell under a cross-off SW breeze. The energy is solid (1112) but the period is a short 8 seconds, so the waves will be a bit weak and crumbly – not the best shape, but for a beginner-friendly spot it’s surfable. Afternoon drops off into messy cross-shore conditions. Monday 27th July morning stays clean with a 5ft ESE swell, 13-second period, moderate energy (1500), and a cross-off breeze – better shape there, but still only a marginal call. The rest of that week into Thursday 30th July is a mix of clean but small, low-energy swells, mostly under 5ft, with nothing to get excited about.

Now, Tuesday 28th July morning is a highlight before the lull: 7ft of ESE swell, 13-second period, very strong energy (1669), and clean with a light W cross-off. That’s a solid, clean combo. The afternoon holds 7ft but picks up a slight cross-onshore bump, so grab the morning.

There’s a bit of a flat spot from Thursday 30th afternoon right through to Monday 3rd August, with only small, knee-to-waist high dribble and mostly clean but weak.

Then – mark your calendar for Wednesday 5th August morning. This is the big standout of the whole forecast. The Gap (Castlepoint) sees 10ft of S swell, period around 10 seconds, but the combined energy is huge (2194) and the wind is glassy. That’s expert territory, way over 8ft, so only for the experienced crew. It’s a rare chance at a heavy, clean day. The afternoon turns onshore and choppy, so it’s a one-session wonder.

The next standout is Friday 7th August morning: another 10ft S swell, 13-second period, even bigger energy (3441), and clean with a light N cross-off. Again, experts only – this is a serious, powerful groundswell. The long period means it might break a bit straight at the beach, but with the right tide it’ll be a belter. The afternoon is wrecked by NE wind.

After that, the swell backs off through the weekend into the start of the following week, with clean but smaller 4ft to 7ft swells and decent shape, but nothing compared to those two epic mornings.

Bottom line: if you’re an experienced surfer, don’t miss the mornings of Wednesday 5th and Friday 7th August – glassy, big, and powerful. For everyone else, the clean 7ft on Tuesday 28th July morning is your best bet for solid but manageable waves.

Rusty.
