The Lowdown
G'day, Rusty here. Look, I've been staring at the charts for Denhams Beach, and I gotta be straight with you – it's a tough run ahead. We've got a solid 16-day window, but honestly, for the entire forecast period, the quality is just not there. The models are showing a whole lot of nothing that's worth paddling out for.
Right from the get-go, Saturday the 12th, we've got tiny 0.7ft wind swell from the ENE and a light cross-onshore breeze. The energy is weak at 18, and it's just poor. That pattern sticks for the whole first week. Sunday the 13th sees a little spike in swell height, but it's a messy 3ft with a 5-second period – that's junk. The wind shifts, but it stays cross-onshore and choppy.
The only time we see a bit of a pulse is Tuesday the 17th afternoon. We get a 7ft swell from the SSE with an 8-second period, and the combined energy bumps up to 643. But the wind is straight onshore from the East, and it's all messy. That's a wave for the kites, not the paddle.
Honestly, the most promising look is Sunday the 20th. For the morning, we get a glassy calm wind, which is a real treat – clean as a whistle. But the swell drops to a tiny 1ft from the East. It’s beautifully clean, but you'll be fighting for ankle-biters with 38 units of energy. It’s a great day for a cruise if you've got a log, but it's not a standout.
We have a run from the 21st to the 27th that's just small, onshore, and poor. The last glimmer is on the 25th where the wind turns clean cross-off from the SW, but the swell is a pathetic 4ft with a 4-second period. For the intermediate or beginner looking at Denhams Beach, it's a generally consistent spot, but the windows of decent swell and good wind just don’t line up in this forecast. With no real standouts and the constant "poor surf conditions" label, I'd say give it a miss for the next couple of weeks. Keep an eye out, forecasts can always change, but right now it’s a flat spell.
Rusty.

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