The Lowdown
Alright, this is Rusty. Let’s size up what’s coming for Port Denison.
We got a stretch of waves lining up, but you gotta pick your moments. First real opportunity is Wednesday morning, July 22 – a clean 6 ft SW swell at 13 seconds. Wind is offshore from the east at 25 km/h, so the surface will be smooth. Wave energy is moderate, about 961. Water temp is 68°, running about a degree colder than average for this time – you’ll notice it but it’s not a big deal.
Wednesday afternoon holds the same 6 ft, period bumps to 14 seconds, wind turns cross-off from the southeast at 20 km/h. Still clean, but not the top pick.
Thursday morning, July 23, brings a solid 7 ft SW swell at 14 seconds with a fresh offshore east wind at 30 km/h. That’s getting into the big range – not for the beginners. Energy jumps to 1624, moderate to strong.
But the real gem is Thursday afternoon. Swell drops slightly to 6 ft, same direction and period, with a gentle offshore from the ESE at 15 km/h. This is your cleanest, most lined-up window in the first few days.
Friday the 24th sees smaller 4 ft in the morning, but the afternoon cleans up with gentle offshore breeze. Energy is dropping to moderate.
Saturday the 25th is small at 4 ft, but Saturday afternoon goes glassy from the northwest at only 5 km/h. That’s a special, clean little session on a smaller day.
Sunday the 26th – not great. Drops to 3 ft with a cross-on breeze making it choppy. Skip it.
Monday the 27th – now we’re talking. Morning has 8 ft SW swell at 14 seconds, light cross-off wind. That’s expert-size, over 8 ft, and the energy is strong at 2223. Afternoon eases to 8 ft but still a heavy groundswell.
Tuesday the 28th – another clean day. 6 ft in the morning with cross-off wind, and the afternoon goes glassy offshore from the east at 5 km/h. That’s a peach.
Wednesday the 29th – very long period 18-second SW swell, but only 4 ft. That’s a proper groundswell. Works best on a reef or point rather than a beach break – might close out.
Thursday the 30th – 5 ft with 16 seconds and offshore east wind at 5 km/h. Clean and very surfable.
Friday the 31st – this is a standout. Morning has 7 ft of SW swell with 16 seconds and glassy conditions. Energy is strong at 2414. This is for experienced surfers only, but it’ll be powerful, clean, and consistent. Afternoon goes to 8 ft with gentle cross-shore wind.
Saturday August 1 – still solid 7 ft, but the wind gets really gusty in the afternoon at 40 km/h from the SSE. That’s kite-surfing conditions, not paddle.
Sunday August 2 – same swell size, but the wind is a fresh 30 km/h cross-off. Clean but messy. Early morning might be okay.
Monday and Tuesday the following week are clean but the swell sits between 4 ft and 7 ft. Tuesday morning August 4 has 7 ft with offshore wind and a long 18-second period – energy is 2877, strong. Very good for experienced surfers.
Then Wednesday August 5 – look out. Swell is predicted at 13 ft from the WSW, and the energy is massive at 8680. That’s way too big for this break. Same for Thursday the 6th at 10 ft. Only for the elite big-wave crew, and even then the forecast says it’s too big for the spot.
Best bets: Thursday afternoon July 23 for a clean 6 ft, and Friday morning July 31 for a powerful, glassy 7 ft. Second week has size but most of it is either blown out or too big to handle.
Rusty.

Information about the Port Denison Surf forecast
The above surf forecast table for 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 Port Denison can be found by selecting the local surf guide option on the grey menu. Our 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 (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 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.
