The Lowdown

G'day, Rusty here. Let's have a look at what's on offer for In-Betweens over the next couple of weeks.

Honestly, the outlook is a bit of a mixed bag. We've got some solid swell on the way, but the wind is going to be a real issue for most of it, keeping the quality down. The water temp is sitting at 80°F which is pretty much spot on average for this time of year, so no surprises there.

The first real chance of anything decent kicks off on Friday the 31st of July. We're looking at a 8ft easterly swell at 8 seconds, but that ENE wind is hammering at 25 mph. It's cross-off, so the face will be clean, but that's a strong breeze making it a battle. The wave energy is massive though, coming in at (1411). With the swell over 8ft, this is expert territory only, and it's just too chunky for most.

Saturday the 1st of August is more of the same – a touch bigger in the morning at 10ft, still that pesky 25-28 mph cross-off wind. The wave energy is still huge (1408), but it's a real handful. The commentary calls it marginal, and I'd agree – it's a full-on, heavy day.

The wind eases a bit through Sunday and Monday, but it's still a fresh breeze. The swell drops from 8ft on Sunday morning down to 5ft by Monday afternoon. The wave energy drops too, from (1122) down to (499). The period stays short at 8 seconds, so it's windswell, not a classic groundswell.

Now, the best of the forecast looks like it's shaping up for Tuesday the 4th of August. The wind finally drops to a gentle breeze of 9 mph, still cross-off. The swell is a manageable 5ft from the ENE, and the period stretches out to 11 seconds. This is a proper groundswell, and the wave energy is a moderate (531). The commentary says "expect very good surf conditions," and for In-Betweens, that's the standout. It's a reef break, so that longer period will draw up some nice lines. It's a beginner-friendly spot, but with the better quality, it might get a few more heads out – crowds are listed as "sometimes," so be ready to share.

Wednesday the 5th still looks okay with a dropping 4ft swell and light winds, but the energy is down to (311). From Thursday the 6th, the wind picks right back up to a fresh breeze, and the surf quality tanks. The swell hangs around for a bit, but the onshore wind just chops it up.

There's a flicker of something on Sunday the 9th of August, with a tiny 2ft swell from the SSW, but get this – the period is 18 seconds! That's a very long period groundswell. The wave energy is (505), but it's a tiny wave. For a reef like In-Betweens, that long period might just produce a few clean, lined-up runners, but it's a gamble on the size.

The rest of the second week is a write-off. Strong winds and poor surf conditions dominate. The energy drops right off, hitting just (51) by the 15th of August. The set-up looks more interesting for kite surfing than paddle surfing through this period.

So if you're after a paddle, your best bet is Tuesday the 4th of August. The winds are light, the swell is a good size, and it's a proper groundswell. It's your standout.

Rusty.
