The Lowdown
Alright, grab your wettie, let's talk surf.
We've only got one break on the radar here for the next couple of weeks: Castlepoint - The Gap. The short-term is pretty grim, to be honest. The water’s sitting at about 55°F, which is about average for this time of year, so nothing crazy there, but things are flat and messy for a while. There's a big gap with nothing worth paddling out for from Wednesday the 22nd right through until Sunday the 26th of July. After that, keep an eye on the charts, because a proper pulse of energy is on the way.
For the first stand-out, you’re looking at Tuesday the 28th of July. The morning kicks off with a thumping 12ft south-east swell, but with a cross-off shore wind, it's still manageable for the experienced crew. Then, things get magic. By Tuesday afternoon, the wind goes glassy, the swell settles a touch to 10ft from the south-east with a long 14-second period. That’s proper groundswell energy, and it’s gonna march right into this sheltered spot. Excellent conditions for those who know what they're doing. It’s going to be a bit too meaty for beginners, but if you've got the skills, this is the session to circle.
Then we roll into Wednesday the 29th of July. The morning has a clean 8ft swell from the ESE with a solid 13-second period and a nice offshore breeze. It’s still in the expert range for size, so the crowd factor at The Gap (which can get "often" busy) might actually spread out a bit. This is another really good window. The swell energy is still strong and the offshore wind will be a dream. The afternoon holds similar size but the period drops slightly.
After that, the consistency fades into a mess of strong winds and lumpy seas for the rest of the first week of August. There is a potential looker on Tuesday the 4th of August, with a 7ft easterly swell and very light wind, but that’s a bit far out – promising, but less certain. If it cleans up, it could be fun for the intermediates and up.
Overall, don’t bother with the next few days. Wait for that last week of July. Tuesday the 28th and Wednesday the 29th are where it's at.
Stay stoked,
Rusty.
