The Lowdown
Alright folks, Rusty here. Let’s get into it.
Well, straight up, the next 16 days are a tough run for In-Betweens. There’s a real lack of quality on offer, and most of the time the conditions are just fighting us. The water temp is sitting at 80°F, which is about average for this time of year, so nothing weird going on there.
The first chance to get wet is on Tuesday the 28th of July. The swell is a solid 8ft from the east, with a 13-second period, packing a punch with a combined energy of 2088. That’s some serious power in the water. But the wind is blowing 16 mph from the north-northeast, making it a cross-off breeze. It’s surfable, but it’s going to be a bit of a battle. This is a reef break, so it will handle the size, but it’s likely too big for beginners.
Wednesday morning the 29th looks a bit more promising. The swell drops to 6ft from the east-northeast with a 10-second period, and the energy is down to 909. The wind is lighter at 6 mph from the northeast, still cross-off. It’s cleaner, and the forecast says “very good surf conditions,” so this is probably the pick of the whole run. That afternoon, the wind goes glassy and the swell drops to a tiny 2ft from the south with a long 14-second period and energy of just 195. It’s clean, but it’s ankle-snappers.
From Thursday the 30th through to the end of the first week, the wind starts to howl. We’re looking at 22 to 28 mph easterly winds, pumping up a disorganized, short-period windswell of 5ft to 8ft. The period is a miserable 8 seconds, and the energy is in the moderate to strong range (600 to 1381). The waves will be there, but they’ll be choppy, blown out, and a mess. It’s more of a kite-surfing setup than a clean paddle session. Definitely not for the inexperienced.
The second week is a long, drawn-out stretch of poor to marginal conditions. From Monday the 4th of August, the swell drops right off, and we’re looking at 4ft to 5ft of short-period junk with strong cross-off winds. The energy is weak, often under 400. There’s a brief pulse of long-period south-southwest groundswell arriving on Sunday the 9th of August, with a 17-18 second period and energy around 600-650. That’s a long-period swell, which at a reef break can produce some nice lines, but the wind is still a stiff 19 mph cross-off, ruining the surface. It’s a looker, not a rider.
Overall, there’s no true standout here. The best window is Wednesday morning the 29th of July, with a decent 6ft east-northeast swell and lighter winds. That’s your one shot. The rest of the time, it’s either too windy, too junky, or too small. A bit of a frustrating outlook, I won’t lie.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for In Betweens may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
