The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the cards for the next couple of weeks.
The first opportunity to get wet won’t be until Friday the 31st of July, and even then it’s a bit of a tease. The real action kicks off from Saturday morning, the 1st of August. We’ve got a solid run of swell coming through, but you’ll need to pick your sessions carefully.
The standout window is the first few days of August. Saturday morning, the 1st, is looking good at Dunes (reef). The swell is 4 ft from the SW, with a long period of 16 seconds – that’s proper groundswell, and it’ll be clean with a moderate offshore wind from the SE. The combined energy is moderate (654). The water temperature is 75°F, which is about average for this time of year. This is clean, lined-up surf for intermediates.
The next real highlight is Wednesday morning, the 5th of August. The swell picks up to 5 ft from the SW, with a very long period of 17 seconds. The energy jumps to strong (1122) and the wind is offshore from the SSE. This is excellent for experienced surfers – the waves will have punch and shape. The period is long enough that the sets will be a bit more spaced out, but that makes for easier paddling and better quality waves.
If you want a session that’s nearly perfect, look at Monday the 10th of August in the afternoon. The swell is 5 ft from the SW, period of 17 seconds, and the wind is glassy – dead calm with a 3 mph westerly. The combined energy is very strong (1456). This is a rare, clean, glassy session for the confident surfer. The waves will have a lot of power, so it’s not for beginners.
The 14th of August, Friday afternoon, is a monster. The swell is 7 ft from the SW, period 18 seconds – that’s big, long-period groundswell. The energy is very strong (2695) and the wind is glassy. However, the forecast does say it might be too big for this break. This is only for experts, and it’s a long way out, so keep an eye on it but don’t book the day off yet.
Overall, the first week is the most reliable. The second week has some promising size, but the conditions are a bit more mixed and the forecasts are less certain. If you’re a beginner, stick to the smaller days below 5 ft, like the 1st and 2nd of August. For the rest of you, the 5th and the 10th are the ones to circle on the calendar.
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.
