The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

First up, we’ve got Dunes, a reef setup that’s exposed to the swell. The water temp is about average for this time of year, so nothing wild there. The best window is shaping up for Monday morning, 20 July. That’s the standout. We’ve got a clean 4ft swell from the SW with a solid 14-second period, and a light offshore breeze from the SSE. The combined energy is moderate (534), and it’s set to be really clean. That’s the session to aim for.

Before that, Sunday morning, 19 July, brings a bigger pulse – 6ft from the WSW with a 15-second period. The energy is strong (1210), but the wind is cross-off from the E, so it’ll be workable. It won’t be as clean as Monday, but for the size, it’s worth a look if you’re after a bit more power.

Tuesday morning, 21 July, has a fresh offshore from the SE at 35 km/h, but the swell drops right back to 3ft. The energy is weak (287). It’s clean, but small. Not worth getting excited about.

Then we hit a dry spell. From Wednesday, 22 July, right through to the end of the month, the swell stays tiny – mostly 2ft to 3ft. The energy is weak, under 300. There are a few glassy moments, like Wednesday afternoon, 22 July, and Wednesday afternoon, 29 July, but the waves are very ordinary. It’s a long gap of about a week and a half with nothing worth paddling out for.

Late in the forecast, around Thursday morning, 30 July, we see a spike back up to 5ft from the SW with a 17-second period and strong energy (1151). The wind is a fresh cross-off from the SSE, so it’ll be clean. Then Friday morning, 31 July, looks promising too: 4ft from the WSW, 15-second period, moderate energy (765), and a moderate offshore from the SE. That’s the second standout – a decent clean swell to wrap up the month.

The first weekend of August, 1st and 2nd, has some size – 4ft to 5ft – but the wind gets messy and the conditions are marginal. Not a clear winner.

So, to sum it up: Monday morning, 20 July is your best bet. Friday morning, 31 July is a close second. The rest is either small and clean or bigger and lumpy. Keep your eyes on the forecast for that long-range stuff, it’s promising but not locked in yet.

Rusty.

Information about the Dunes Surf forecast

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