The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this forecast is a tough one to write. I’ve been staring at the charts for this stretch, and I gotta say, it’s a long, quiet road ahead. We’re looking at a 16-day run that starts off flat and stays pretty poor all the way through. There’s a big gap of nothing good for the first week, and honestly, the only real pulse of energy shows up way down the line, but it’s gonna be a messy one.

The first real surf we see is in the middle of the second week. On Monday, August 9th, there’s a late push. The swell comes up to 6 ft from the WNW, with a period of 12 seconds. That’s proper groundswell, packing a lot of punch – the combined energy kicks up to 767 (strong to very strong). But here’s the catch: the wind is howling from the NNW at 19 mph, right on the cross. It’s fresh and lumpy. For a spot like Reef, which is an exposed, advanced-level reef break, this is expert territory. The water’s sitting at 70°, which is about normal for this time of year, so nothing weird there.

Now, the real standout in this whole bleak outlook is the morning of Sunday, August 9th. That’s your best bet. We’ve got 6 ft of WNW swell, with a solid 12-second period, and the combined energy is a massive 767. The wind is cross-shore from the NNW at 19 mph, which is fresh but not fully onshore, so it’ll still be lumpy. This swell is too big for beginners, and with that period, it’ll be a proper groundswell – better suited for a place like this reef than a beach break. It’s going to be powerful, but the quality is shot by the wind. Still, if you’re an expert and you’re desperate, this is the only window worth paddling out for.

Later in the week, on Tuesday, August 11th, the swell holds around 5 ft from the NW, but the wind is up to 22 mph, making it a total mess. The energy is still high at 685, but it’s just too rough to be any fun. The rest of the run is tiny, weak, and blown out.

Honestly, for most of this period, the conditions are so poor and the wind is so strong that this setup looks more interesting for kite surfing than paddle surfing. If you’ve got a kite, you might have a blast. For the rest of us, it’s a waiting game. Forecasts can change, and it can’t stay this poor forever, but right now, plan on a long break.

Stay salty,
Rusty

Information about the Reef Surf forecast

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