The Lowdown

Alright folks, Rusty here. Let's have a look at what the next couple of weeks have in store for us at In Betweens.

Right off the bat, the water temp is sitting at 80°F, which is bang on average for this time of year – nothing weird there, just your typical warm summer bath.

The overall picture is a bit of a mixed bag, to be honest. We've got a constant stream of easterly wind and swell, but the wind is almost always coming from the side or cross-off, which is manageable, but not the glassy perfection we'd all love. The energy in the water is there, with combined swell energy readings often in the three-digit range, and even hitting four digits at times (1605), so there's definitely push behind it, but the quality is held back by that constant breeze.

Sunday the 26th is a write-off for a surf – the wind is a stiff 22 mph cross-off, and the swell is only 4 ft. It's just not worth suiting up.

Things start to look a little more interesting from Monday the 27th. The swell ticks up through the week, hitting 7 ft by Tuesday the 28th morning and 8 ft that afternoon, with the energy reading hitting a strong 1944. But here's the thing – the period is 12-14 seconds, which is proper long-period groundswell. For a reef setup like In Betweens, that's actually a good thing; it'll focus the energy and give you some clean, lined-up waves. The wind stays cross-off though, 12-19 mph from the NE. It's surfable, but it won't be silky smooth. This is the best run of the first week really – Monday and Tuesday have some size.

By Wednesday the 29th, the wind swings onshore from the SSW at a light 6 mph, but the swell starts to drop off quick, losing period too. Things go downhill from there. Thursday and Friday the 30th and 31st see the wind cranking up to 25 mph. That's nasty. The swells are still around 7 ft but with short, weak period (8 seconds) and that howling cross-off breeze, it's going to be a messy, blown-out mess. Honestly, that setup looks more like a kite-surfing session than a paddle session.

The first week of August is much the same story – solid 8 ft to 10 ft of swell on the 1st and 2nd, but with that relentless 25-28 mph wind, it's just too ugly to recommend. The energy is there (1325), but the quality is zero. There's a bit of a drop on the 3rd, and then a slight recovery on the 4th with some 6 ft, 12-second swell and the wind down to 16 mph. That's the best looking day in the second week. It’s still cross-off, but a moderate breeze is heaps better than a strong one, and that longer period (12s) will give the waves some proper shape.

After that, it tails off into tiny, junk surf through to the 8th of August. We're talking 1 ft to 2 ft – just not enough to ride.

The window closes on Sunday the 9th of August with a pulse of 7 ft, 7-second windswell and the same old 22 mph cross-off. It’s surfable if you’re desperate, but it’s not your best bet.

So, if I had to call it, the standout window is Tuesday the 28th of July for the biggest, most powerful swell (8 ft, E, 12s), but you'll be dealing with a solid cross-off breeze. For the cleanest conditions with a decent wave, I’d point you to Tuesday the 4th of August – swell is 6 ft from the ENE with a 12-second period and the wind drops to a moderate 16 mph. It’s not perfect, but it’s the best compromise between size and quality we get in this whole outlook.

Stay salty,
Rusty

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.
