The Lowdown

Alright, Rusty here. Let’s talk about the waves ahead.

First few days are dead. Small, messy, not worth a look. There’s a gap of about four days with nothing to ride. The first real chance is Friday July 19th, but it’s still nothing special.

The standout is the weekend of August 1st. That’s where you want to be. Before that, Monday July 20th morning has a clean moment—offshore wind, 4ft SW swell with a 14s period, and moderate wave energy (534). Water temp is about 77°, a bit warmer than average for this time of year, so it’s comfortable.

But the real deal is Saturday August 1st. Morning brings a 7ft SW swell with a 16s period, strong offshore wind from the SE at 18 mph. The wave energy is pumping (1964). That’s big, expert territory. The afternoon gets even better: 7ft SW swell, same long period, and the wind turns to a light cross-off, keeping it clean. Energy jumps to 2617. Dunes is a reef, so that long-period groundswell will line up nicely.

For the rest of the forecast, there are a few marginal mornings with clean conditions on July 21st and 27th, but the swell is small and inconsistent. July 31st has a 4ft WSW swell with a 16s period, but the wind is cross-off, so it’s a maybe, not a must.

Bottom line: save your energy for the weekend of August 1st. That’s your best window. The water’s warm, the swell’s solid, and the wind is on your side. The early week is a bust.

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.
