The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer at Dee Dees over the next couple of weeks.

Overall, it’s a bit of a mixed bag. We’ve got some serious size coming through, but the wind is going to be our biggest enemy for the first week or so. The water temp is sitting at 54°F, which is right about average for this time of year, so no surprises there.

The first real chance to get wet looks like Sunday the 2nd of August. It’s not a standout, but it’s the first glimmer. The morning shows a 7ft swell from the south, with a period of 11 seconds, giving us moderate wave energy (1068). It’s a cross-shore breeze from the northwest, which is alright, but it's only a gentle breeze so there will be a slight cross-chop. The afternoon drops off to 4ft and gets a bit more cross-onshore, so the morning is your better bet.

Monday the 3rd is small, with 3ft to 4ft, and the wind stays messy. Not worth paddling out for.

Now, here’s where it gets interesting, but also a bit intense. From Tuesday the 4th through to Wednesday the 5th, we’ve got a massive pulse of swell. Tuesday morning shows a 15ft south swell with a very long 14-second period and strong wave energy (7536). The wind is a fresh cross-onshore though, making it messy and lumpy. Wednesday the 5th is similar, with a 10ft to 8ft south swell, but the wind drops to a light breeze by the afternoon. The problem is, this swell is too big for Dee Dees. Over 8ft, this is strictly for experts only, and the cross-shore conditions won't help. It’s a powerful, long-period groundswell, but at a reef break, it could be a handful.

The real standout appears on Thursday the 6th of August. This is the best on offer. We’ve got a 6ft south swell in the morning, dropping to 5ft in the afternoon, with a 11-second period. The combined energy is moderate (927). But the magic is in the wind – it’s glassy. Dead flat, no wind, just clean, smooth lines. This is the window. The morning will be perfect, and the afternoon will hold the same quality. This is your day.

Friday the 7th drops off fast to 2ft, and the wind goes light offshore, but the swell is too weak to get excited about.

Saturday the 8th of August has a nice little 4ft south swell with a very long 14-second period. The wind is light and cross-offshore, making for clean conditions. It’s a long-period swell, so it might break a bit straight on the reef, but it’ll be clean. The afternoon is glassy with 3ft waves. Good, small fun.

Sunday the 9th sees a 6ft bump from the SSE with a short 8-second period. The wind is light and cross-off, so it’s clean, but the short period means less push.

After that, the second week gets messy. The 10th and 11th of August have some size, but the wind is all over the place. The 11th of August morning has a nice offshore wind from the northeast with a 6ft SE swell – that’s a promising window, but it’s a week away, so keep an eye on it. The 13th of August morning also has a light offshore breeze and a 5ft swell, but the period is a short 7 seconds, so it’ll be a bit weak.

The rest of the week into the 15th of August is blown out or too small. The 15th is a write-off with near gale cross-onshore winds.

So, to sum it up: Thursday the 6th of August is the absolute standout. Glassy conditions and a solid 5ft to 6ft south swell. That’s your golden ticket. The Sunday the 2nd of August is a warm-up, and the Saturday the 8th of August is a good backup. If you’re an expert, the 5th of August might be worth a look, but the size is intimidating and the wind is tricky.

Rusty.

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.
