The Lowdown

Alright, let’s get into it. The next couple of weeks are a mixed bag, to be honest. We’ve got a lot of big, raw energy early on, but it’s coming with some messy wind. The good stuff is squeezed into a few windows, so you gotta pick your moments.

First thing’s first, the swell we’re seeing now is substantial, but it’s not clean. The water temp at Dee-Dees is sitting around 54°, which is pretty much normal for this time of year, so no surprises there.

We start off rough. This Sunday morning we’re looking at a solid 13ft of south swell hitting Dee-Dees, but with a strong southerly cross-breeze and light rain, it’s gonna be a washing machine out there. The combined energy is strong, reading at 2979, but it’s all over the shop. Don’t even bother.

That south energy keeps pumping into Monday, still too big and still cross-shore. We're talking 8ft on the morning, and the call is that it’s simply too much for this break. The combined energy is moderate at 1024, but the wind is gonna make it a tough paddle.

Things back off a bit on Tuesday, but the wind swings around to the southwest, and it’s onshore. The swell drops to 10ft, but the conditions are just poor. And by the afternoon, it jumps back up to 16ft with a strong cross-onshore wind. That’s a beast, but an ugly one. The energy is way up there at 4471.

Wednesday keeps that west/southwest juice coming, with the swell staying in the 12ft to 15ft range. The period’s getting longer, up to 12-14 seconds, which usually means better shape, but the wind is still a cross-onshore mess. It’s just a lot of water moving with no order to it.

Then we get a window. Thursday morning, the 20th, the wind drops out completely, going glassy. We’ve still got a solid 6ft of south swell with a 12-second period, and the energy has backed off to a moderate 850. This is looking like the first proper chance to get some clean waves. It’s not huge, but it’ll be fun.

Friday the 21st looks alright too. The swell has eased a touch to 5ft, but the period is a long 16 seconds, which is a proper groundswell. A light north cross-offshore wind is keeping it clean in the morning. It’s a bit more challenging, a long-period swell like that, but at Dee-Dees, a reef, it should handle it well.

The weekend after that, the 22nd and 23rd, it just dies. The swell drops right off and the wind gets strong and cross-shore. There’s nothing doing, and we’re looking at combined energies under 500. It’s flat and messy.

Now, we have a bit of a reset on Monday the 24th. There's a small, clean bump of swell, around 2-3ft, but it’s from the SSW and has a long 14-second period. The wind is offshore in the morning, light ENE, and it’s glassy. It’s not big, but it could be a fun little cruiser session. The energy is weak, around 220, but sometimes that’s all you need.

Another window opens on Wednesday the 26th. The morning looks great – clean with a cross-offshore wind, and the swell is pushing 6ft from the SSW. It's a little bit bigger and should have some push to it. The energy is moderate at 634.

Thursday the 27th is also looking fine, with clean conditions and a smaller, fun 3ft of swell.

We’ve got one more date to circle on the calendar. Sunday the 30th. There’s a solid groundswell building, with 7ft of south-southwest swell and a 15-second period. The wind is light and cross-offshore, so it should be clean. The energy is strong, at 1956, but the catch is, it might be pushing the limit for Dee-Dees. It’s a big one, but if you're an experienced surfer, this could be the standout of the second week. The call is that it's too big for this break, so it might be a paddle battle. Then, into Monday the 31st, it settles down a touch to a cleaner 4ft with the same clean, light winds. That could be the pick of the bunch for a lot of folks.

So, the standout day here is that Thursday the 20th – glassy and clean with a solid groundswell. The other one to watch is that Sunday the 30th if you’ve got the skills for the size. Otherwise, there are a couple of smaller windows for a grovel on the 24th and 27th.

For the big days with the strong cross-winds, to be honest, this setup might be more interesting for the kite surfers than for us paddle surfers.

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.
