The Lowdown
Alright folks, Rusty here. Let’s take a long, hard look at what’s on the cards for the coming weeks. We’ve got a single spot on the menu, and it’s a bit of a mixed bag, so let’s get into it.
First up, we’re looking at a bit of a flat spell right out of the gate. The first real surf to talk about isn’t until Sunday the 19th of July, but the conditions are a letdown. The In-Betweens is a reef break that’s exposed and likes a solid SSE swell, but we’re getting a lumpy, cross-off wind from the ENE at 22 mph, smashing into a 5-ft swell from the same direction. The period is a short, weak 8 seconds, making for a pretty ugly, choppy mess. The water is sitting at a comfortable 80°F, about average for this time of year, so that’s one small positive. But honestly, the combined energy is moderate at best (425), and we’re calling it poor surf. Not worth paddling out for.
Monday the 20th is similar—still cross-off winds, still messy. The swell drops to 4.6 ft on the morning, and we get a weird shift in the afternoon to a tiny 2.6 ft south swell with a long 16-second period. That’s a groundswell, but it’s just too small and the wind is still junk. The scores are all one and two out of ten, which says it all. This is a kite-surfing setup, not a paddle-surfing one.
We’ve got a long stretch of nothing really good until the 22nd of July. The morning of the 22nd is still poor, but the afternoon shows a glimmer. The swell jumps to 4.9 ft from the ENE, and the period stretches to 11 seconds. The combined energy shoots up to 1144, which is strong. It’s still cross-off wind, but it’s at least clean. The score is a 2/10, so it’s marginal, but it’s the best we’ve seen.
The 23rd and 24th are a write-off. The 23rd has a tiny, long-period south swell—2.3 ft at 20 seconds—but it’s completely blown out by a 25 mph wind. The 24th brings a bigger, 6.6 ft to 6.9 ft ENE swell, but the period is a pathetic 7 seconds, and the wind is howling. It’s a wall of whitewater.
Now, the weekend of the 25th and 26th of July is where things start to get interesting. The 25th morning has a 6.6 ft ENE swell with an 8-second period, combined energy of 1147, but the wind is still a fresh 19 mph cross-off. The afternoon gets a long-period 3.0 ft SSW swell (18 seconds) that pushes the energy even higher to 1195. The 26th morning is a 3.9 ft E swell at 16 seconds, with a lighter 16 mph wind, and the combined energy is 1169. The score creeps up to a 3/10, which is the best we’ve seen. It’s still marginal, but it’s clean. The swell direction is E, not the optimum SSE, and the wind is cross-off, not offshore. It’s promising, but not a standout.
The best of the whole forecast looks like it falls on the 27th and 28th of July. The 27th of July morning is a 4.9 ft E swell with a 14-second period, moderate wind at 16 mph, and a combined energy of 1460. The 28th of July morning is a 6.6 ft ENE swell with a 13-second period, and the energy is 1523. That’s strong wave energy, folks. The swell is a bit big for beginners (over 5 ft), but it’s not huge, and it’s a reef break. The period is long, meaning it’ll be a proper groundswell, with good shape and power, but it’ll have long lulls between sets. The break is fairly consistent, but crowds are possible. The wind is still cross-off, which is a shame. If the wind ever turns offshore, this spot would be pumping. As it stands, the 28th morning is the pick of the litter, but it’s still a marginal call.
The end of the month and into August is a slow fade. The 30th and 31st of July are tiny, poor, and blown out. The 1st of August has a 5.6 ft ENE swell with a 7-second period, which is just junky. The 2nd of August morning has a 3.9 ft SSW swell at 16 seconds, with a lighter 9 mph easterly wind that is actually a true cross-shore, not a cross-off. The combined energy is 1464. The score is a 3/10, and it’s

Information about the In Betweens Surf forecast
The above surf forecast table for In Betweens provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at In Betweens can be found by selecting the local surf guide option on the grey menu. Our In Betweens surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (In Betweens) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
