The Lowdown

Alright folks, let’s get into it. Dee Dees is the spot for the next 16 days, and it’s a real mixed bag.

The first action kicks off Monday afternoon, July 20th, with a big SSW groundswell pumping in at 10 feet. The water temp is sitting at 54°, which is dead average for this time of year. The problem? That swell is too big for the break to handle, so it's a no-go for paddling. The energy is extreme at 5316, but it's not our friend today.

Now, Tuesday morning, July 21st, is where it gets interesting. The swell drops to 7 feet from the SSW, with a 14-second period, giving us a solid 1474 energy reading. The wind is light and cross-off from the NNE, cleaning it right up. That's a proper window for experienced surfers. The afternoon stays clean with 5 feet of SSW swell, but it's still a little on the big side.

Wednesday, July 22nd, is a real treat. Morning has 4 feet of S swell, but it’s the afternoon that steals the show. Only 3 feet of S swell, but the wind goes glassy from the SW, and the energy is a light 315. You’ll be sharing waves with maybe a few others, but it'll be worth it.

Thursday morning, July 23rd, we’re down to 2 feet, and the energy is weak at 117. It’s surfable, but don’t get your hopes up. The afternoon goes to hell with a 35 km/h NNW cross-wind and a messy 5 feet of NW windswell.

From Friday, July 24th, through Sunday, July 26th, it’s a write-off. Fresh to strong winds, lumpy cross-chop, and rain. The swell is all over the place, but it’s junk. The energy is moderate but the conditions are terrible.

We get a bit of a reprieve on Monday, July 27th, and Tuesday, July 28th. Clean, small waves around 2 feet to 3 feet from the SSW, with light winds. The energy is low, but it’s clean enough for a log. It’s not a standout, but it’s a session.

Then we hit another flat slump. From Wednesday, July 29th, all the way through to Saturday, August 1st, the conditions are poor. Windswell from the NW, strong breezes, and messy chop. There’s a brief moment on Sunday, August 2nd, where a massive 15 feet SSW swell rolls in, but it’s way too big for the break. The energy is a staggering 4692, but it's a warning, not an invitation.

The real standout is the tail end of the forecast. Monday afternoon, August 3rd, delivers a glassy 5 feet SSW groundswell with a 15-second period and 1226 energy. The wind is glassy, the conditions are excellent for experienced surfers. That’s the one to circle on the calendar. Tuesday, August 4th, has a 8 feet SSW swell, but it’s borderline too big again cropped up by moderate cross-off wind.

So, to sum it up: Tuesday morning, July 21st, is the best early option for the experienced crew, and Monday afternoon, August 3rd, is the true standout—glassy, solid groundswell, and clean. The rest of the window is either too big, too windy, or too small.

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.
