The Lowdown

Alright folks, Rusty here with a look at what’s coming up for Scar Reef. We’ve got a run of swell on the cards that’ll make the next couple of weeks interesting, but not all days are created equal.

The water’s sitting at a very normal 80°F, which is bang on for this time of year – no temperature surprises.

The forecast kicks off with a solid 4ft SSW groundswell, with a long 15-second period and combined energy of 1076 (moderate energy). It’s clean, with light SSE cross-off winds. Saturday morning the 25th looks like a nice way to get the ball rolling, but the better stuff comes later.

Sunday the 26th morning sees a bigger pulse – 8ft from the SE, period just 9 seconds, with offshores. The energy jumps right up to 1761. It’s a punchy, short-period swell and it’s offshore clean, but at this size it’s starting to get pushy for anyone but experienced surfers.

Monday the 27th holds a cleaner 5ft to 6ft, with the same SE direction, period picking up a little but still short. Offshores again, wave energy moderate, and the conditions are good for a solid surf.

Now, from Tuesday the 28th through to Friday the 31st, the swell backs off a touch to the 3ft to 4ft range, but the quality takes a real step up. We’re seeing consistent light offshores, and the period stretches out to 14-19 seconds. Those longer-period groundswells from the SSW are bringing cleaner, more defined lines and easier paddle outs. Keep an eye on Thursday the 30th afternoon – 3ft but with a 19-second period and clean, light offshores. That’s going to be smooth and fun.

The standout for the first week is Saturday, 1st August. The morning starts glassy, with a 4ft, 16-second SSW groundswell rolling in. The combined energy is climbing to 1765. It’s still a manageable size with no wind – just you and the ocean. The afternoon bumps up to 6ft with a long 18-second period, and the energy jumps to 2101. It’s described as excellent for experienced surfers, and with light ESE cross-off winds, it’ll be clean. This is a perfect day for anyone comfortable on a bigger board.

A big call for the next weekend: Saturday, 8th August. This is a promising long-range call but less certain. The forecast is for a solid 10ft SSW groundswell with a very long 18-second period. The combined energy is a massive 5104. This is very strong energy, and it’s offshore to cross-off. At 10ft and with such a long period, this is serious, powerful groundswell. It’s going to be very long lines, heavy sets, and for experts only. The period makes it a classic point or reef wave, but it might straighten out a beach break. Keep it on the radar.

Crowds are listed as “sometimes” possible at Scar Reef, so it’s not usually a zoo, but don’t expect solitude.

The forecast finishes with Sunday, 9th August still showing 8ft SSW swell, offshore wind, and very strong energy. No shortage of swell, but it’s a surf for the confident crew.

Overall, there’s a lot to like here. The first week offers a nice mix of smaller, quality days, while the second week looks to build into something much bigger and more serious. If you’re an experienced surfer, that 1st of August is your top pick.

Rusty.

Information about the Scar Reef Surf forecast

The above surf forecast table for Scar Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Scar Reef can be found by selecting the local surf guide option on the grey menu. Our Scar Reef 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 (Scar Reef) 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 Scar Reef 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.
