Table - best surf conditions forecast for In Betweens over the next 16 days.
Right, let’s have a look at what’s coming up for In Betweens. This one’s a reef break, beginner-friendly, but it’s pretty exposed out there. The water’s sitting at 80°, which is about normal for this time of year, no real surprises on that front.
The next 16 days are a bit of a mixed bag, to be honest. There’s swell on offer, but the wind is a persistent issue. That ENE wind is blowing cross-offshore pretty much the whole time, which is frustrating because it’s keeping the surface clean but not quite giving us that magic offshore glass. The swell energy is moderate through the early period, with values around 636 (moderate wave energy) to start, building up later.
For the first week, from Wednesday 8th July through to the end of the weekend, we’ve got surf in the 6 ft to 8 ft range, but the quality is just not there. It’s a short period swell, around 7 to 8 seconds, so it’s going to be a bit lumpy and lack the push you’d want. The wind is a fresh to strong breeze, 19 to 25 mph, which is a lot of puff for a beginner spot. The conditions are consistently described as poor or marginal. Honestly, it’s a bit of a grind. You’d be paddling into wind-affected, short-period lines that close out more than they wall up. If you’re a kite surfer, this setup looks a lot more interesting than it does for a paddle surfer.
The first real standout is a bit of a late bloomer. Look at Monday 21st July. The combined swell energy jumps to 1012 (strong wave energy), and the period stretches out to a very long 18 seconds. That’s proper groundswell, and it’s coming from the east. The swell height is small, only 2 ft to 3 ft, but with that long period, it’s going to be a lot cleaner and more powerful than the numbers suggest. The wind drops to a moderate breeze of 16 mph, which is the lightest we’ll see. This is a promising window for In Betweens, but remember, that long period groundswell can be a bit straight at a beach break, so a reef like this might actually focus it into something nice. The score is a 2, which is the best we get.
Then again on Tuesday 22nd July, we’ve got another day of that long-period groundswell, 4 ft at 15 seconds, with the wind still a fresh breeze but manageable. The energy is still strong at 1072 (strong wave energy). This is the best on offer in the whole run. The swell direction is east, but the optimum for this break is SSE, so it’s not a perfect match, but the quality of the swell and the lighter wind make it the pick of the bunch.
After that, it drops off fairly quickly. The last few days of the outlook, into Wednesday 23rd July, are back to short-period, weak energy and poor conditions.
So, to cut a long story short: the first week is a write-off for quality – just too much wind and not enough period. The standout is the 21st and 22nd of July. That long-period groundswell is your best shot, but it’s a small swell, so you’ll need a bigger board and a bit of patience. It’s a promising but not certain call this far out.

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.
