The Lowdown

Alright, surfers, Rusty here. Let’s have a look at what’s heading our way.

Alright, the next two weeks are a real mixed bag. We’ve got some serious, heavy-duty swell on the way, but it’s going to be a game of patience. The real standout window is this weekend and into Monday, but you’ve got to be sharp. The water is sitting at a pretty normal 55°F, so no surprises there.

The first proper call is for Dee Dees on Saturday afternoon, the 18th of July. We’re looking at a solid 7ft SSW groundswell rolling in with a very long 22-second period. The combined energy is massive at 4197, so there’s a lot of power in the water. The wind is light and offshore from the west, which is a major positive. However, this is a reef break, and with that much size and period, it’s going to be a serious, heavy wave. It’s not for the faint-hearted. If you’re an experienced surfer who knows the reef, it could be a classic session. For beginners, it’s a no-go.

Sunday the 19th offers some relief in size, with 6ft and 6ft SSW swell, but the wind switches to a cross and cross-onshore, messing up the surface. The energy is still high (1886 and 1570), but the conditions are just marginal. I’d give it a miss.

Now, Monday morning, the 20th of July, is your other standout. The swell is 8ft from the SSW with a 19-second period, and the wind is glassy from the ESE. That’s the recipe for perfection. The energy is huge at 3654. Again, this is a big reef wave, and over 8ft it’s for experts only, so at 8ft, it’s in that advanced-to-expert territory. The afternoon gets bigger at 10ft, with even more energy (5372), but the wind goes cross-shore, taking the shine off. The morning is the moment.

Tuesday the 21st is a bit of a letdown. The swell drops to 7ft in the morning (still big), but the wind is cross-offshore, offering clean conditions. The afternoon is better for experienced surfers, with 6ft SSW swell, clean conditions, and light offshore wind. The energy is 1079. It’s a good session, but not the standout.

After that, we hit a long dry spell. From Wednesday the 22nd all the way through to Tuesday the 29th of July, the surf is small, weak, or just blown out. The swell drops to a paltry 4ft on Wednesday, and the energy is a mere 364. It’s mostly poor with strong onshore winds. There’s a big dump of 12ft SSW swell on the 26th, but it’s accompanied by 15-18 mph cross-onshore wind, making it a choppy, ugly mess. That setup is more interesting for kite surfing than paddle surfing.

The window reopens on Wednesday the 29th of July. The morning brings a clean 6ft NW swell, with light cross-offshore winds. The energy is low at 294, and the period is a short 6 seconds, so it’ll be a bit lumpy and disorganized. It’s a surfable, ordinary wave. The afternoon is similar.

And that’s it for the forecast. The first week is the real deal for the brave, and the second week is a long, quiet wait.

Rusty, signing off.

Information about the Dee Dees Surf forecast

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