Alright mate, let’s talk about what’s cooking at Castlepoint - The Gap.
We’re starting slow, but there’s a decent pulse of swell coming through later in the first week if you can wait. Water temp is about 55°, which is normal for the season.
Sunday morning kicks off with chest-high waves around 5ft from the ENE, period about 8 seconds. Wind is a light cross-off out of the north, keeping it pretty clean. Wave energy is moderate (407). It’s surfable for beginners, but the short period means it’s a bit gutless.
Then we hit a rough patch. Monday through Thursday of the first week is mostly messy – the swell gets bigger, but the wind turns onshore or stays crappy. Tuesday afternoon sees a big jump with 13ft from the east and a 10-second period, but light rain and a cross wind spoil it. Energy is very strong (5379), but that’s just raw power, not quality.
Here’s the real highlight. Wednesday, 8 July morning is the one. The Gap gets a solid 10ft southeast groundswell with an 11-second period, and the wind is offshore from the WNW. That’s clean, powerful surf. Combined energy is very strong (2363). This is for experts only – anything over 8ft gets serious. Crowds are often here, so expect a few heads.
After that, it goes south. Thursday and Friday bring a strong southerly change with onshore winds and lumpy, choppy conditions – not worth it. Saturday and Sunday the 12th are still poor with strong onshore winds and rain. The swell stays big, but the quality is gone.
In the second week, things settle. Tuesday, 14 July morning has about 7ft from the ESE with an 11-second period, and a light cross-off wind from the north keeps it clean. Energy is strong (1476). Not as punchy as the 8th, but a solid option.
The rest of the second week drops off. Wednesday the 15th has clean 6ft waves, but energy fades (925). By the 16th and 17th, the swell drops below 3ft, and while the wind is offshore, it’s blowing fresh to strong, making it a chore. The 18th offers tiny 3ft glassy conditions from the SSW with a very long 14-second period – that’s a longboard day if you’re keen.
Best bet in this 16-day window is definitely Wednesday morning, 8 July. Get it while it’s clean.
