The Lowdown
G'day, Rusty here. Looks like Dongara-Port Denison is about to fire up after a bit of a slow start. We've got a solid run of south-west groundswell on the way, but it takes a few days to really get going. The first couple of days are just a warm-up, so don't expect much until later in the week.
Tuesday morning, the 21st, sees a clean 5ft SW swell roll in with a 14-second period and a gentle cross-offshore breeze. The energy's still pretty moderate (791), so it's a decent starter but nothing to write home about. The afternoon picks up a bit to 5ft, and the energy jumps to 1048 – still clean, but the tide might be a factor. Wednesday morning, the 22nd, is looking better with a clean 6ft SW swell and a nice offshore easterly at 12 mph. The 13-second period is solid, and the energy is moderate (961). This is where it starts to feel like a proper session.
The real standout is shaping up for Thursday, the 23rd. The morning gets a bit of a fresh breeze, but the afternoon is the pick: 6ft of SW swell at 14 seconds, with a gentle offshore breeze from the ESE. The energy is strong (1402), and the conditions are described as excellent for experienced surfers. This is a clean, powerful wave with good shape. Friday, the 24th, hangs in there with a 4ft morning and a 4ft afternoon, both clean and with offshore winds, but the energy drops off.
Now, for the absolute best of the bunch, you have to look at Monday, 3rd August. That's a week and a half away, so keep an eye on it, but the signs are incredible. The morning is showing a 13ft SW groundswell with a very long 18-second period. The energy is enormous (8606), and the wind is light and offshore, making it clean. This is a big, powerful, deep-water swell – expert territory only, for sure. The reef setup at Dongara-Port Denison (a reef break) is perfect for this kind of long-period groundswell, as it won't just close out.
The water temp is about average for the time of year, no major anomalies to report. Just your standard winter wetsuit.
Summary: The best windows are Thursday afternoon, 23rd July, for a solid, clean 6ft SW swell, and the big-picture standout is Monday, 3rd August, with a massive, clean 13ft SW groundswell. That second one is a long way out, but it's the one to circle on the calendar if you're an expert. The rest of the period is a mix of smaller, cleaner days and some messy, windy afternoons, especially from the 29th through to the 1st of August, which looks more like a write-off with strong cross-onshore winds. Expect crowds to be possible, especially on the better days, as the word gets out.
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.
