The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.

We’ve got a bit of a mixed bag shaping up. The standout window is actually a little way off, so we’ll need to be patient. The first really good session doesn't arrive until the 29th of July, but it's a beauty. After that, the wind picks up something fierce, and we’re in for a long, blustery stretch before things clean up again in the second week of August.

The Good Stuff

The best bet on the whole forecast is In Betweens on Wednesday afternoon, the 29th of July. The water’s sitting at a balmy 80°, which is pretty much spot on for this time of year. We’ve got a solid 5ft swell coming from the ENE, with a period of 9 seconds pushing through. The combined energy is moderate at 645. But the real winner here is the wind – it’s coming straight out of the East at just 3 mph, leaving the surface glassy. Expect very good surf conditions. This is the one to circle on the calendar.

The Long, Windy Middle

Following that one perfect afternoon, things get a bit wild. From Thursday the 30th of July right through to Monday the 3rd of August, the wind is relentless. It’s blowing a gale out of the ENE at 22 to 28 mph. While the swell bumps up to 7ft and even 8ft, with combined energy climbing into the strong range (1379 on the 1st of August), the wind is just too strong for clean paddle surfing. The waves will be messy and blown out. For the experienced crew, the 8ft days on the 1st and 2nd of August are expert-only territory given the chop. Honestly, with that strong breeze and a beach setup, this looks more interesting for kite surfing than paddling.

The Second Week Promise

The wind finally eases back from the 4th of August. The swell drops a touch, but the quality comes back. Tuesday afternoon, the 4th of August, is a solid call with clean conditions, a 5ft ENE swell, and a nice long 11-second period. The combined energy is moderate at 554, and the wind is a gentle 9 mph. Expect very good surf again.

Then, on Monday the 10th of August, a new swell fills in from the SSW. It’s a long-period groundswell at 16 seconds, so it’ll have plenty of energy (580) and those long, clean lines. The height is only 3ft, but that period will make it wall up nicely. The wind is a gentle 9 mph, keeping things clean. This is another standout morning for a longer, more relaxed session. That long period will be best at the reef itself, as it can be a bit too straight for a beach break.

All in all, that first Wednesday is the clear winner, with a couple of nice options on the 4th and the 10th of August to keep things interesting.

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.
