Table - best surf conditions forecast for Castlepoint - The Gap over the next 16 days.
G’day, Rusty here. Look, I’ll be straight with you—this isn’t a classic run for Castlepoint - The Gap. The first few days are a write-off, with strong south winds and big, messy swell. The wait is on, but once she cleans up, we’ve got a couple of real gems.
The first suggestion is a Sunday morning glass-off on July 12th. The Gap (Castlepoint) will be tiny, around 3ft from the SSW with a 13-second period. The combined wave energy is weak (433), but that glassy wind and clean conditions make it a sneaky little session if you’re desperate. The water temp is about average for the time of year at 55°F.
Now, the real standout is Saturday July 18th. We’ve got a 5ft SE swell, 13-second period, and light offshore to cross-off winds from the WSW. That’s clean, lined-up surf with moderate energy (1038). It’s not too big, not too small—just right. Crowds are often a factor here, so get in early.
The second-week highlight is Tuesday July 21st. Tuesday morning sees 4ft from the S with a very long 16-second period, offshore WNW wind, and strong energy (1365). That’s a point-break dream. By Tuesday afternoon, it’s a flat calm glass-off with 4ft S swell at 15 seconds. That’s about as good as it gets for this stretch.
The rest of the window is a mixed bag of small, clean days with shorter-period swell, or blown-out rubbish. July 17th brings a solid 6-7ft SE groundswell with 16-second period, but that strong SSW wind will ruin it. If you’re a kite surfer, that day might be worth a look.
Stay patient, get on that Saturday the 18th, and don’t sleep on the 21st.
Rusty.
