The Lowdown

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

Alright, straight up, I gotta be honest with you – this forecast is a bit of a grind for the most part. We’re looking at In Betweens, a reef break that’s a beginner-friendly spot, and the swell is hanging around for a while, but the wind is the real story here. It’s going to be a persistent cross-off breeze from the ENE for the bulk of the period, which will keep the surface clean, but the wave quality is just not hitting the mark for most of it. The early days are a real mixed bag too.

We kick off on Monday the 27th of July with a clean 5 ft wave from the east, but honestly, it’s a marginal call. The next few days, the swell picks up a bit, hitting 7 ft to 8 ft on Tuesday the 28th, but the wind is still a cross-off from the NNE. The water temperature is sitting at 80°, which is about normal for this time of year, so no need for a long john just yet. The combined energy is strong, reading 1820 and 2070, but the forecast is still calling it marginal. By Wednesday the 29th, the wind swings to a light SSW cross-on, which is a bit messy, and the swell drops back to 7 ft and 5 ft. The energy is fading fast into the 600s and 900s.

Now, the real bummer hits from Friday the 31st of July right through to the 8th of August. The wind is howling out of the ENE at 22 to 28 mph. It’s a cross-off, so the surface is clean, but the swell is a short-period, wind-driven 7 ft to 8 ft mess. The wave period is down to 8 seconds or less, meaning it’s just a lumpy, choppy pile of water. The energy fluctuates, but it’s mostly in the 900 to 1300 range. This is not for the faint of heart, and honestly, with that much wind and that short period, a beach setup would be more interesting for kite surfing than a paddle session. It’s a solid week of poor to marginal surf.

The third week of the forecast, starting around Monday the 3rd of August, the swell drops to 5 ft, but we’re still stuck with that ENE cross-off wind. The energy drops significantly, down to 500-600 range. It’s a bit of a slump.

Now, here’s a glimmer of hope. Right at the very end of the forecast, on Tuesday the 11th of August, we get a real shift. The wind goes light and glassy, turning offshore from the north. The swell is only 3 ft, but it’s a long-period 15-second SSW groundswell. The energy reading is 512. This is the kind of clean, lined-up, long-period groundswell that can make a reef break like In Betweens sing. It’s a small window, but if you can get on it, the conditions will be very good. Because it’s a long-period swell, it’ll be a bit more picky, but the reef setup is perfect for it.

So, the standout window is that Tuesday afternoon, the 11th of August. It’s the only real clear winner in the whole 16 days. The rest is a waiting game with a lot of wind and short-period slop.

Rusty.

A general guide to surfing at In Betweens can be found by selecting the local surf guide option on the grey menu.

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.
