The Lowdown
G’day, Rusty here. We’ve got a solid run of groundswell on the way for Dongara-Port Denison, but the wind’s going to play games with us. The first few days are a write-off or marginal, then we get a proper window of clean conditions that really hits its stride from Thursday morning the 3rd. The water's sitting at 67°, which is about spot on for this time of year – no nasty surprises there.
Wednesday morning the 2nd is a no-go for me. We’ve got 7 ft of SW groundswell with a 14-second period, but the south wind is light cross-shore, leaving a bit of bump on the surface. Combined energy is 1580, which is moderate, but the quality is marginal. That afternoon only gets worse – more wind, more chop.
Thursday morning the 3rd is the real standout here. The wind drops right off – glassy, slight air, and you’ve got 8 ft of SW groundswell rolling in at a long 15 seconds. Combined energy jumps to 2424, solid moderate wave energy, and it’s clean as a whistle. That’s for experienced surfers – over 8 ft stuff is for experts only. The direction is straight out of the optimum W for this reef, so you’ll get proper lines. Expect waves around chest to head high with plenty of push. This is the session to aim for. Afternoon turns onshore and messy, so get in early.
Friday the 4th is blown out, Saturday the 5th is a disaster – 37 mph wind, 12 ft swell, total chaos. Sunday the 6th and Monday the 7th have cleaner cross-off winds but the swell is big (12 ft to 13 ft) and the wind is strong, so that’s expert territory only. Combined energy is through the roof – 6007 on Monday morning – but the conditions are just marginal.
Then we hit a really nice window. Tuesday morning the 8th has offshore east wind at 16 mph with 8 ft of SW groundswell at 15 seconds. Clean, moderate offshore breeze, and that’s a proper session if you’re competent. By Wednesday morning the 9th, same setup but the swell drops to 7 ft – still clean, offshore, and excellent for experienced surfers. Energy is 1788. That afternoon stays clean with an east wind dropping to 6 mph.
After that, the wind turns cross or onshore through the 10th and 11th, and the swell fades a bit. But then Saturday morning the 12th brings another gem: 8 ft of SW groundswell, a 16-second period, gentle offshore east wind at 9 mph. Clean as. Combined energy is 3089, strong wave energy. This one’s for the crew who can handle overhead waves.
Sunday morning the 13th has a smaller but glassy 6 ft swell with light offshore east wind – that’s a great all-rounder session, clean, less intimidating. The rest of the second week is a mix of cross-shore winds and bigger swells, but Wednesday morning the 16th stands out again: 5 ft of very long-period SW groundswell at 19 seconds, light cross-off wind, combined energy 2789. That kind of period will produce long, lined-up waves perfect for a reef setup like this – expect some proper walls, but the sets will be spaced out. Good paddle in.
No other cracks in the armour worth chasing. Overall, Thursday the 3rd morning and Saturday the 12th morning are your best bets. Get out there.
Rusty.

Information about the Dongara-Port Denison Surf forecast
The above surf forecast table for Dongara-Port Denison provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dongara-Port Denison can be found by selecting the local surf guide option on the grey menu. Our Dongara-Port Denison 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 (Dongara-Port Denison) 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 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.
