The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for In Betweens.

We’ve got a couple of small windows in the 16-day outlook, but to be honest, the first week is a bit of a write-off. The surf is either tiny, messy, or the wind is just too strong. From Friday 7th August right through to the middle of the next week, it’s mostly marginal to poor, with a lot of cross-off winds and a fair bit of energy in the water that just isn't lining up for a good paddle. The combined energy readings are often in the moderate range (between 100 and 999), but the quality just isn't there.

The first real standout I can see is shaping up for the morning of Wednesday 19th August. We’ve got a solid 6 ft of swell rolling in from the ENE, and the wind is going to drop right back to a gentle 9 mph cross-off. That’s going to be clean. The combined energy is at 510 (moderate), and the period is a decent 9 seconds, so it should have a bit of push. The guidance says this spot is a pretty consistent reef break, and it’s exposed to the swell, so it’ll be working. Keep in mind the crowds are sometimes around, so you might have to share. For a beginner-friendly spot, that 6 ft is right on the edge of being too big for a learner, so consider yourself warned.

Another one to watch, though it’s a bit further out, is the morning of Saturday 22nd August. The swell drops right off to 2 ft, but it’s a much longer period SSW groundswell at 16 seconds. The combined energy is 491 (moderate), and we’ve got gentle 9 mph offshore winds from the ENE. That long period can make a reef like In Betweens really fun, with clean, lined-up waves. It’s a promising call, but we’re a week and a half out, so keep your fingers crossed.

Water temp is sitting at 81°, which is about 0.9° above normal, so about average for the time of year. Nothing to worry about there.

Overall, it’s a patchy outlook with a few bright spots. The best on offer is that Wednesday 19th August morning session. Don’t hold your breath for the first week, but the second half of the window has some promise.

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.
