The Lowdown

Alright, Rusty here. Let’s have a proper look at what’s coming our way.

You know, looking at the whole 16-day picture, it’s a bit of a mixed bag for Dee Dees. The first week starts out pretty flat and messy, but there’s a couple of windows that get my heart racing. The standout is definitely Saturday the 12th and into Sunday the 13th, with some serious size rolling in, but that’s for experienced heads only. The cleaner, more manageable windows come early in the second week.

We start off Monday the 7th with a bit of a whimper. There’s a lumpy 6ft swell from the south, but it’s short-period and the wind is a cross-off from the southeast at 12 mph. The water is a touch warmer than normal at 56°, about 2° above average for this time of year. It’s not really doing it for me. That carries on through Tuesday and Wednesday, with the swell dropping right off – Tuesday morning is just 3ft from the SSW with a 10-second period, clean enough but gutless. The energy is weak, barely registering. Wednesday is even smaller.

Thursday the 10th is a write-off. Strong winds from the northwest at 19 mph make a mess of things, and the swell is a confused, short-period 4ft from the northwest. Don’t bother.

Now, Friday the 11th is the first real glimmer. Early morning, we get a glassy, clean 2ft swell from the SSW, but here’s the kicker – it’s got a very long 18-second period. That’s proper groundswell energy, and the combined energy is a solid 444. It’s small, but those long-period lines will be clean and have some push. The wind is glassy from the WNW at just 3 mph. For a reef break, this could be a nice little session for the early birds, but it’s small.

The big one kicks off Saturday the 12th. Saturday morning sees a 5ft SSW swell with a 13-second period, and the energy is already pumping at 716. The wind is light cross-shore from the NNW. It’s decent, but the real show is Saturday afternoon. The swell jumps to 10ft from the SSW, same 14-second period, and the energy is a massive 3030. That is serious. The wind is a gentle cross-onshore, but the report says it’s too big for this break. This is for experts only. If you have to paddle out, know your limits. Sunday the 13th stays big – 8ft in the morning and 7ft in the afternoon, both with that long 14-second period, and the energy is still huge (2546 and 1676). The wind stays light, but it’s cross-onshore for the morning. Again, this is big, powerful reef swell.

The pick of the week for the skilled surfer is Monday the 14th. Monday morning, the swell drops to a still-chunky 7ft from the SSW, 13-second period, and the energy is 1377. The wind is a clean cross-off from the north at 6 mph. The report calls it excellent surf conditions for experienced surfers. That’s your window.

Tuesday the 15th is a step down but still clean. You’ve got a 4ft swell from the south with an 11-second period, and the wind is a light cross-off from the north. Energy is 444. It’s a solid, fun day.

After that, the run gets messy again. Wednesday the 16th is onshore and choppy. Thursday the 17th is a write-off with strong winds. Friday the 18th is a messy 10ft onshore goulash. Saturday the 19th and Sunday the 20th are just windy and poor.

The final glimmer comes Monday the 21st and Tuesday the 22nd. Monday sees a clean 4ft SSW swell with a 14-second period, light cross-off wind from the east-southeast, and the energy is 472. Monday afternoon goes glassy with a 3ft, 13-second SSW swell. Tuesday morning is a bit smaller but with a massive 19-second period, giving an energy of 822, though the wind is a gentle cross-shore from the southeast. It’s marginal, but those long lines will be there.

So, to wrap it up: The standout is Monday the 14th morning. Clean, solid 7ft south swell, cross-off wind, and a reef break ready to handle it. That’s for the experienced. The second best is the glassy Friday the 11th morning for the long-period small stuff, or the cleaner Tuesday the 15th morning. The big Saturday and Sunday are for the brave.

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.
