The Lowdown
G’day, Rusty here. Been staring at the charts for Castlepoint - The Gap and there’s a bit of a slow start, but some real gems hiding in the second half of the week.
First up, the water’s sitting at 54°F – that’s about 0.9°F cooler than normal for this time of year, so pretty average, nothing to shock the system.
The surf kicks off Sunday morning, August 2nd, with a clean 8ft S swell swinging in at 11 seconds. That’s a moderate groundswell, and the wind is a gentle offshore from the WNW. The water’s glassy, the vibe is clean. The combined energy is strong at 1574, so there’s some punch. This is a beginner-friendly break, but 8ft is pushing it for newbies. Still, it’s the pick of the opening days. Sunday afternoon turns lighter with a 6ft S swell, still offshore and clean.
Monday, August 3rd, drops a bit to 4ft and 4ft from the SSE and SSW, but the wind picks up to a moderate offshore. It’s surfable, but nothing special.
Now, Tuesday August 4th through Wednesday August 5th – the swell goes nuts. We’re talking 15ft to 16ft from the SSW and S, period hitting 12-13 seconds, and combined energy screaming into the thousands (6144 to 9818). That’s massive. But the wind is strong cross-off and cross, and the break is sheltered. It’s too big for this spot, really only for the brave and experienced. The forecast notes say it’s too big for the break. I’d call it a spectator day.
Thursday August 6th morning brings a nice reset: 5ft SSE swell at 10 seconds, gentle offshore W wind, clean. The energy is moderate (1152). That’s a solid session. Friday August 7th morning is a real standout – 4ft S swell with a very long 17-second period, light offshore W wind, and clean. The combo of that long period and offshore wind at Castlepoint? That’s a point break dream. The energy is 1408. This is the best on offer. The only catch is this spot is “fairly consistent” and “often” crowded, so expect company.
Saturday August 8th morning is glassy – 6ft S swell, 12 seconds, and glassy wind from the W. That’s a treat. The afternoon gets a bit onshore, so morning is the move.
After that, the surf drops off into the second week. Sunday August 9th to Wednesday August 13th is mostly small, weak, and messy. We’re talking 2ft to 3ft, short periods, onshore winds, and poor conditions. The energy drops below 100 at times. There’s a gap of several days where there’s really nothing to recommend.
Thursday August 14th morning shows a spike to 6ft NE swell at 9 seconds, but it’s short period and the wind is cross-off. Not great. The rest of the second week is similar – small, wind-affected, and disappointing. The very end of the forecast (August 17th) has a 6ft S swell but with strong offshore winds, so it’s clean but the energy is only 669, and the period is short. It’s a maybe.
Standout call: Friday August 7th morning is the one. 4ft S swell, 17-second period, light offshore W wind, clean. That’s a beautiful session at Castlepoint - The Gap.
Rusty.
