The Lowdown
Morning crew, Rusty here. Let’s get you across the next couple of weeks at Shipwrecks.
We’ve got a solid run of clean, rideable swell coming up, starting this Tuesday morning and stretching right through the end of the month. The standout windows are the mornings—light offshore or cross-off winds, clean faces, and that reef setup doing its thing. The water’s sitting at 80.6°, which is pretty much spot on for this time of year, nothing weird there.
Tuesday morning kicks off with a clean 5 ft SW swell, 15-second period, and a moderate offshore breeze out of the SE. The energy’s moderate at 1006, and it’s looking tidy. The afternoon goes cross-off, still clean, but the tide gets a bit questionable, so make the most of the morning session.
Wednesday eases into a 5 ft SSW swell, 15 seconds, with a gentle offshore breeze in the morning. Clean conditions, good energy at 992. Afternoon stays clean but cross-off, still worth a paddle.
Thursday is where it starts to perk up—5.6 ft SSW, 14 seconds, energy jumps to 1302. Still clean with light cross-off winds. This is a proper fun day, waves holding some shape off the reef.
Friday backs off slightly to 4.6 ft SSW, 14 seconds, but the morning offshore is light and glassy. Energy drops to 728, but it’s still clean and fun. Good day for a relaxed session.
Saturday drops a touch more—3.9 ft down to 3.3 ft SSW, 14 seconds—but it’s still clean and rideable. Not big, but the reef will sort it out.
Sunday swings back up: 5.2 ft SW, 16 seconds, moderate energy around 1240–1365. Morning is clean with light cross-off, but the afternoon gets a bit tricky with tide. Still, the long period means decent push and shape.
Monday the 21st keeps that 5.2 ft SW swell with a 14-second period, light offshore in the morning, energy around 1082. It’s a solid clean day, good for a proper session.
Tuesday the 22nd fades to 3.6 ft SW, 13 seconds, lighter energy at 585. Morning’s clean with light breeze, but the afternoon wind picks up to 20 km/h and the tide’s iffy. Not a write-off, but not the pick.
Wednesday the 23rd is a standout—5.9 ft SSW, 16 seconds, energy jumps to 1654. Clean, cross-off breeze, strong shape. This is one of the better days on offer, you’ll want to be out there.
Thursday the 24th settles to 4.9 ft SSW, 14 seconds, energy 934. Clean and consistent, good morning session.
Friday the 25th drops to 4.3 ft SSW, 13 seconds, still clean but a notch down in energy. Good for a longboard if that’s your style.
Now, Saturday the 26th is the big one. The swell jumps to 8.2 ft in the morning, 9.8 ft by afternoon, with a 21-second period in the morning and 20 seconds in the afternoon. Energy is massive—5543 in the morning, 6314 in the afternoon. This is proper groundswell, and it’s only for experienced surfers. The morning is clean with a gentle offshore, but the afternoon has that big swell and moderate breeze—still clean, but this is not a day for the faint-hearted. Over 8 ft, so experts only.
Sunday the 27th stays heavy—9.8 ft in the morning, 8.2 ft in the afternoon, 18-second and 17-second periods. Energy still huge at 4981 and 3977. Light offshore in the morning, clean again, but again—this is for experienced surfers only. Paddling out will be a mission, but the reef will hold some proper shape.
Monday the 28th eases to 6.6 ft then 6.2 ft SSW, 16–15 seconds, energy around 1983 and 1639. Still solid, clean conditions, but dropping. Good day for strong intermediate to advanced surfers.
Tuesday the 29th backs off to 4.6 ft in the morning, then drops to 3 ft in the afternoon with a super long 18-second period. Energy comes back up a bit at 1210, but that’s a long-period swell, so it might break a bit straight on the reef—still clean, but check the tide.
Wednesday the 30th finishes the run with 5.6 ft SSW, 16 seconds, moderate offshore in the afternoon, energy around 1341–1307. The morning has a cross-off breeze and questionable tide, but the afternoon is clean and offshore, a good closer.
Overall, the best on offer is Saturday the 26th and Sunday the 27th for the sheer size and power, but it’s expert-only. If you want clean, fun, manageable waves, Thursday the 17th and Wednesday the 23rd are your picks. The long-period swells are best handled
