The Lowdown
Alright folks, Rusty here. Let’s get into it. Just one spot on the radar for this stretch, and it’s a proper reef setup that demands respect.
We’ve got a bit of a slow burn to kick things off. The first real window of opportunity hits Saturday, July 25th. The morning is looking tidy with a clean 6 ft southerly swell, a solid 11-second period pushing some moderate energy through (790). The westerly offshore breeze is going to have it looking smooth. That’s your best bet early on. The afternoon fades a bit with a smaller, weaker swell and a cross-onshore breeze that’ll mess with the face.
Sunday, July 26th is a bit of a tease. The morning has a bigger 7 ft southerly swell and more energy (1033), but the wind is cross-off, so it won’t be as clean as Saturday morning. Still, there’ll be some size. The afternoon turns choppy with a cross-onshore.
Monday, July 27th has a small, clean morning with 4 ft southerly swell and a light offshore, but it’s weak energy (234). After that, the surf drops right off.
From Tuesday, July 28th right through to Friday, August 7th, we’re in a long, flat spell. There’s barely any energy in the water – we’re talking combined swell energy values dropping to double digits (44) and single digits. A few tiny pulses come through, but nothing worth paddling out for. The winds are mostly off or clean, but you can’t surf what isn’t there.
Then, hold onto your board. Saturday, August 8th is the standout, but it’s for experts only. We’ve got a massive 21 ft southerly groundswell hammering in with a 12-second period. The combined energy is a staggering 12109 – that’s very strong, serious power. The morning is clean with a moderate cross-off breeze, but the size is well over 8 ft, so unless you’ve got a lot of experience and a big wave gun, stay on the beach. The afternoon is still huge at 20 ft, still clean, with the energy barely dropping (9979). The wind is gentler, making it a better window for the big-wave chargers.
Sunday, August 9th hangs on with a 16 ft southeasterly swell, but the wind goes cross-shore and there’s some light rain, making it a bit less inviting.
The standouts here are clear: Saturday morning, July 25th is your best bet for a fun, clean session without the crazy size. But the real story, the one that’ll get the adrenaline pumping, is Saturday, August 8th – that’s a massive, clean, powerful swell for the experts. Don’t even think about it if you’re not ready for it.
Stay sharp, and keep your wetsuit zipped.
Rusty.

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