The Lowdown

Alright, Rusty here. Let’s get into it.

Alright, let’s have a look at what’s cookin’ at Dongara-Port Denison. We’ve got a proper run of swell on the way, but mate, you’ve got to pick your moments. The water temp is sitting about average for this time of year, so no surprises there.

The real standout is Sunday morning, the 9th of August. This is the one. We’re looking at a solid 13ft SW groundswell with a very long 17-second period. That’s proper, heavy energy pumping in – we’re talking 9655 for the combined energy. This is a reef setup, and with that period, it’s going to be well-shaped but will be pushing some serious water. That ESE breeze at 6 mph is cross-off, keeping things clean. This is for experts only – it’s big, powerful, and not a place for the faint-hearted. If you’ve got the balls and the skill, this is the session of the window.

Sunday afternoon drops a touch to 12ft from the SW, still with a long 16-second period, and the wind goes glassy with a 3 mph southerly. It’s still exceptional for experts, but slightly less grunty (7608 energy). Still, a beautiful, clean afternoon.

Monday the 10th is a write-off. That WNW wind jumps to 16 mph, onshore, turning the surf to slop. Not worth paddling out.

Tuesday the 11th bounces back nicely. Morning gets a 13ft SW swell, 16-second period, with an ESE cross-off at 12 mph. That’s big and clean. The combined energy is very strong at 8010. It’s a marginal call on the tide, but with that wind and size, experienced surfers will be in their element. The afternoon is similar but with a southerly cross-off; still solid.

Wednesday the 12th and Thursday the 13th offer smaller, cleaner waves for the experienced crew. We’re looking at 10ft and 8ft SW swells in the mornings, with easterly offshore winds. The energy drops into the moderate range (4272 and 3335), but it’s still fun, clean, and well-shaped. The afternoon sees a bit more cross-shore chop.

Friday the 14th keeps that trend going with an 8ft SW swell and offshore easterly winds in the morning – another clean, fun day for experienced surfers.

Then we hit a bit of a lull from the 15th to the 16th. The swell drops to under 6ft, energy falls off to the weak to moderate side, and the winds get a bit messy. Not a terrible paddle if you’re desperate, but nothing to get excited about.

The 17th and 18th are ugly – strong onshore winds and lumpy, poor conditions. The 19th of August shows a glimmer with a clean morning, 8ft SW swell, and a NE cross-off. It’s decent for experienced surfers. The swell direction shifts a bit more WSW later.

The 20th is another write-off with strong onshore winds and big, messy swell (15ft on Thursday morning). Keep the board in the car.

The final weekend (22nd and 23rd of August) has some cleaner moments. Saturday morning the 22nd is looking glassy again with a 7ft SW groundswell and 15-second period. It’s clean, good for experienced surfers, but the energy is moderate. Sunday the 23rd is smaller and less consistent.

The absolute best on offer is that Sunday morning, the 9th of August. Big, powerful, clean, and for experts only. The second stand-out is Tuesday the 11th for a solid, clean morning session.

Alright, that’s the story. Catch you on the inside.

A general guide to surfing at Dongara-Port Denison can be found by selecting the local surf guide option on the grey menu.

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 Dongara-Port Denison 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.
