The Lowdown

G'day, Rusty here. Look, I've scanned the charts for the next couple of weeks, and honestly, it’s a bit of a mixed bag for us. There's surf on the table, but you've got to pick your moments and keep your expectations in check. This isn't a window of endless perfection; it's more about snatching a few decent windows between the wind and wonky conditions.

Our main break in the spotlight is In Betweens, a beginner-friendly reef. The water temp is sitting at 81°F, which is pretty much what you'd expect for this time of year.

The story starts quiet. From Saturday, the 8th of August, right through until about Wednesday morning, the 12th, it’s mostly a write-off. The swell is small and junky, and that fresh 18-22 mph ENE cross-off wind is just making a mess of things. The wave energy is moderate at best, with readings around 400-500 (combined swell energy). Not worth paddling out.

We finally get a flicker of hope on Wednesday the 12th. The morning sees a clean 3ft swell rolling in from the S, with a nice long 18-second period. That groundswell energy jumps up to 939 (moderate), which is promising. The wind is still a cross-off from the ENE, but the quality of the swell is miles better. The swell direction isn't the absolute best for this spot (it loves a SSE swell), but that long period should wrap in okay. Thursday the 13th holds similar potential, with 4ft from the S and a 16-second period, and very strong wave energy around 1054. The wind does pick up to a strong 25 mph breeze, but it stays clean. These are the best windows in the first week, but they're still marginal.

Now, here’s where it gets wild. Saturday the 15th of August. The afternoon session shows a massive 33ft swell from the E with a 14-second period. The combined energy reading is a colossal 40341 (very strong). This is not a day for a beginner or even most intermediates. The wind is a moderate 12 mph cross-shore, so the conditions are actually workable, but that size is pure, serious, expert-only territory. On a reef like this, it’ll be a heavy show. The very next morning, Sunday the 16th, drops to a still-chunky 12ft from the SSE, with a moderate breeze. It's cleaner, but still a big step up from normal.

After that, the swell drops out quickly. Monday the 17th sees a return to 3ft from the S with a slow 14-second period, but the wind is back up. The rest of the second week, from the 18th through the 23rd of August, is a frustrating pattern of small, short-period ENE wind swell (4ft to 7ft, period around 6-8 seconds) and persistent cross-off winds. The energy readings are weak to moderate, mostly under 600. It’s just not going to offer any quality.

For the standout, I’d recommend the Wednesday morning, the 12th of August, at In Betweens. That 3ft of long-period S groundswell with clean, cross-off wind is your best chance for a fun, clean session on your shortboard or fish. It's not perfect, but it's the best of a tough run.

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.
