The Lowdown
Alright, let's look at what's happenin' at Castlepoint - The Gap. This spot is sheltered, so it needs a proper nudge to wake up. For a beginner wave, it can be a bit of a letdown, and we've got a good stretch of quiet to start.
First up, Monday the 7th and Tuesday the 8th are a total loss. Fresh cross-onshore winds and lumpy, poor surf with combined energy readings of 424 to 708 (moderate energy). Leave the stick in the car.
Wednesday the 9th morning, things get a bit more interestin'. The wind goes glassy, dead calm, with a 5ft swell from the ESE. The energy drops to 309 (weak), but that glassy surface is a big win – it'll be clean as a whistle, even if the waves are a bit ordinary. That's a window for a patient session.
Thursday the 10th gets a strong offshore, but the swell is tiny, only 2ft in the morning, droppin' to 1ft by the afternoon. It's clean but hard to paddle into.
Now, here's where it gets a bit special. From Friday the 11th through Saturday the 12th morning, we've got some proper conditions comin' together. On Friday morning, we get a clean, gentle offshore breeze from the west with a 6ft swell from the south (moderate energy of 524). By the afternoon, it's light offshore and clean with a 5ft swell. That's good, clean surf. Saturday morning looks even better – light offshore winds, 7ft of south swell (moderate energy of 769). This is the standout window. Clean waves for the more experienced, with a bit of size.
Saturday afternoon though, the swell jumps to a massive 15ft from the SSW with a long 12-second period, and the combined energy goes ballistic at 9706 (strong to very strong energy). That's way too big for this break, and only for experts if they're feelin' crazy. It's a pass from me.
Sunday the 13th stays big with a 10ft to 12ft south swell, but the winds turn cross-off and cross, makin' it messy and marginal.
Monday the 14th brings another good window. Moderate offshore from the WNW with a 8ft south swell (13-second period, very long period groundswell) and an energy of 1844 (strong). That's a solid, clean swell, but that long period might make it break a bit straight at the beach. Still, a good option for the crew who know the bank.
After that, the second week drops off. Tuesday the 15th has moderate offshore winds but the swell drops to 5ft, then smaller. From the 16th onwards it's mostly poor with tiny waves or strong winds. A couple of marginal days pop up around the 20th with clean but small 3ft to 4ft south swells, but the wind is fresh to strong offshore, which can be a battle to get out.
The best of the whole period is hands down Friday the 11th through Saturday the 12th morning. Clean, gentle offshore, solid 5ft to 7ft south swell, and it's the most consistent action we'll see. Get on it.
