The Lowdown

Righto, Rusty here. Let’s have a look at what’s coming down the line for Dee Dees.

We’re staring at a bit of a wait, to be honest. The first few days are a write-off with messy, cross-onshore winds and a dodgy swell. Sunday the 19th is a no-go – 6ft to 7ft of SSW swell, but it’s got a 16-second period and the wind is junk, cross-on or cross, making for choppy, lumpy conditions. Not worth paddling out for.

The real standout is Monday morning the 20th. That’s the one to circle. We’ve got a solid 8ft of SSW groundswell with a very long 18-second period, and it’s glassy – dead calm. The water is sitting at 55°F, which is about average for this time of year. The combined energy is massive (3580), and the wind is true offshore. This is a reef break, so that long-period swell will line up beautifully. It’s going to be clean, powerful, and consistent. The only catch – it might be a bit much for beginners at 8ft, but for the experienced crew, this is premium. The afternoon stays clean with a light cross-shore, but the swell bumps up to 10ft (energy 5372), so it’s expert-only territory.

Tuesday the 21st still has some punch. Morning brings 7ft SSW swell (14 seconds) with a clean cross-off breeze from the NNE. Energy is 1622. Nice and clean. The afternoon drops to 6ft with a lighter 13-second period, but still clean. Still good waves for the experienced surfer, but not as epic as Monday.

After Tuesday, the quality drops off a cliff. Wednesday the 22nd has a small 4ft S swell, glassy in the morning but weak – energy is only 341. Then from Thursday the 23rd all the way through to the end of July, it’s a long stretch of poor conditions. Strong winds, lumpy chop, blown-out surf. There’s a big gap of no good surf from the 23rd to the 31st.

Now, looking way out, Thursday the 30th of July has a massive 16ft SSW swell forecast, with a 12-second period and light offshore wind in the morning. The energy is enormous at 7296. But that’s huge – only for the most experienced chargers, and it’s a long way off, so treat it with caution. The following day, Friday the 31st, still has a solid 8ft S swell with a clean cross-off breeze, but again, it’s a week and a half away.

For the first week of August, Saturday the 1st has a small 4ft S swell and clean morning wind, but it’s weak (energy 405). After that, it’s back to strong winds and messy conditions through Sunday and Monday.

So, to wrap it up: Monday the 20th of July, morning session is your absolute best bet – glassy, solid groundswell, and clean. Tuesday the 21st morning is a solid backup. After that, you’re waiting until the very end of the month for another big pulse, but that’s a long-range gamble.

Rusty out.

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.
