The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s cooking for the next couple of weeks at In Betweens. Straight up, I gotta be honest with you – this is a tough stretch. The first few days are flatter than a late arvo pint, and the quality is all over the shop. The core issue is that persistent ENE wind. It’s cross-off, so it’s not completely ruining the face, but it’s blowing hard enough to keep the scores low. The water temp is about what you’d expect for the time of year, nothing weird there.

We kick off Saturday the 25th. The morning has a bit of size, a 6.9ft swell from the ENE, but it’s short period at 8 seconds and the wind is a fresh 22 mph. The combined energy is moderate (1170). It’s a bit of a mess for a beginner wave. The afternoon drops right off to 3.0ft, even if the period improves to 18 seconds.

Sunday the 26th and Monday the 27th are pretty similar. We’re looking at waist to chest-high waves, 3.0ft to 4.9ft, with a long period of 14-16 seconds. The wind eases a touch to 16 mph on Monday. The energy is solid, in the 1000s, but that long period on a reef like In Betweens can make it a bit fat and straight. It’s clean, but not what you’d call firing.

Tuesday the 28th is the first real standout. The morning is 6.9ft from the E at 13 seconds, and the afternoon bumps up to 8.2ft from the E. The combined energy gets strong (2744) in the arvo. That’s a proper swell. The wind is still cross-off from the NE at 16-19 mph, so it’s going to be clean. This is the best of a tricky run – decent size, good energy, and clean. It’s a bit big for beginners, but the experienced crew will be on it.

Now, Wednesday the 29th looks like a write-off. We get a 9.8ft swell from the ENE in the morning, but the wind swings onshore from the SSE at 9 mph. The wave comment is “marginal” and the score is a 1. That’s a big, messy, blown-out lump. The afternoon drops to 6.6ft and the wind goes S, still onshore. Leave the board at home.

Thursday the 30th through to the weekend of August 2nd-3rd is a bit of a grind. The swell stays around 5.2ft to 8.2ft, but the period drops to a short, weak 8 seconds. The wind stays strong from the ENE, 22-28 mph. The energy is moderate, but that short period means the waves will be lumpy and weak. The surf is clean, but it’s just not holding any shape. For the 31st of July and 1st of August, with that strong breeze and 8.2ft of short-period swell, this setup looks more interesting for kite surfing than paddle surfing.

Then we get a promise. Tuesday the 4th of August. The morning is a bit cross-shore, but the afternoon… the wave comment says “expect very good surf conditions” and it gets a score of 3. The swell is 5.6ft from the ENE at 12 seconds, the wind is just a light 6 mph cross-off, and the water is clean. The energy is moderate (878). The crowd is listed as “sometimes,” so you might have a few mates out, but this is the session to chase. It’s a classic, clean, long-period reef wave.

After that, things fade out fast. The 5th of August drops to 4.3ft, and by the 6th, we are down to 1.3ft with only 80 energy. That’s a flatter than a lake. The 7th, 8th, and 9th of August are just poor – 5.6ft to 6.2ft from the ENE, strong breeze, and the wave comment is “poor surf conditions.” That’s a hard pass.

So, the best on offer is without a doubt Tuesday the 28th of July for the biggest swell, and Tuesday the 4th of August for the absolute best quality and clean conditions. The rest is a battle against the wind.

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.
