The Lowdown
Alright, this is Rusty. Let’s have a proper look at what’s on the table.
We’ve got a solid stretch coming up, but it kicks off with a bang. The pick of the whole 16-day window is this Sunday morning, the 2nd of August, at Wainui Beach - Stockroute. We’re talking a clean, offshore WNW breeze at 6 mph, and a healthy 6 ft SSE groundswell rolling in with a 12-second period. That’s proper wave energy – the combined energy is sitting at 1067, which is moderate to strong stuff. The water’s sitting at 56°, which is just about normal for this time of year, so no surprises there. This is a solid, powerful option for experienced surfers, and with the offshore wind, it’ll be holding nice lines. Just keep an eye out – crowds can pop up here sometimes.
Sunday afternoon drops off a bit. The wind swings to a light cross-onshore from the SSE, and the swell drops to 5 ft. It’s still surfable but nothing like the morning.
Monday the 3rd is a bit of a fade. Morning has a solid WNW offshore at 12 mph, but the swell drops to 4 ft. The energy is down to 317. It’ll be clean, but you’re working for the waves. Monday afternoon goes glassy with a 3 ft SSE swell and a 10-second period – pretty, but small. Energy’s only 258.
Now, Tuesday the 4th is where things get weird. The morning is a write-off – strong cross-shore wind, lumpy. But Tuesday afternoon? The swell jumps to a massive 13 ft from the south at 10 seconds, with combined energy hitting 4231. That’s serious, powerful stuff. But here’s the thing – that’s too big for this break. Unless you’re an absolute expert and you know the spot inside out, this is more of a spectacle than a session. The wind is cross-off and clean, so the lines will be there, but that size is a major caveat. Beginners, stay well away.
Wednesday the 5th is a full-on no-go. Strong winds, messy cross-chop, and a massive 15 ft south swell. That’s ugly. Same story for Wednesday afternoon. Don’t bother.
Thursday the 6th is a return to something more manageable. A 8 ft SSW swell in the morning with a moderate cross-off wind – it’s surfable, but it’s not a standout. The energy is 2441, so there’s power, but the wind isn’t perfect. Afternoon drops to 6 ft from the south.
Friday the 7th morning is clean again. Light WNW offshore at 3 mph, with a 4 ft SE swell. The period is 10 seconds, so it’s not a groundswell, but it’ll be fun for a cruisy session.
Friday afternoon brings a weird one. A tiny 2 ft SSE swell but with an 18-second period. That’s a very long period groundswell, so it’ll have heaps of energy for its size, but it’s cross-onshore and choppy. Not ideal. This kind of long-period swell can break too straight at a beach break, so look for the points or reefs if you’re keen.
Saturday the 8th is a nice little comeback. Morning has a clean NW offshore at 6 mph, a 5 ft SE swell with a 13-second period. That’s a proper groundswell, and the energy is 730. This is a solid, clean option for a session. Afternoon goes a bit cross-onshore, so hit the morning.
Sunday the 9th afternoon is actually the second standout of the window. The morning is clean but small, but the afternoon brings a 5 ft SE swell with a 15-second period, combined energy of 1241, and clean, light variable winds. That’s a gorgeous combination for experienced surfers – long-period groundswell with clean conditions. This is worth marking on the calendar.
From Monday the 10th through to Wednesday the 12th, things get small and clean but underwhelming. Waves drop under 3 ft, energy falls away. Good for a log or a learner session, but not for anyone hungry for power.
Then from Wednesday the 12th afternoon all the way through to the end of the outlook on Monday the 17th of August, it’s a long, drawn-out period of poor conditions. Cross-shore winds, lumpy chop, tiny swell – there’s a solid 5-day gap of no real recommendations. The energy drops into double digits, and the swells become weak and short-period. There’s a tiny window on Sunday the 16th afternoon with glassy conditions and a 2 ft SE swell, but it’s ordinary. By Monday the 17th, a strong offshore wind rips through but the swell is only 1 ft.
So, to boil it down: Sunday morning, 2nd of August is the standout – strong, clean, and powerful. The backup is Sunday afternoon, 9th of August – clean, long-period, and full of potential. The rest is either too small, too messy, or too big for most.
This is Rusty. Get the early sessions.
