The Lowdown
Alright, let’s get real about Denhams Beach. It’s a pretty exposed spot, beginner-friendly, very consistent, but the next week and a half is looking pretty grim. The water temp is sitting around 63°, which is pretty normal for this time of year, so at least a wetsuit won’t feel like a shock.
We’ve got a long stretch of small, weak, and messy surf ahead. The best chance to get wet is actually gonna be Sunday morning, the 16th of August. Glassy conditions with a light southwesterly breeze, and a small 4ft swell from the ESE. It’s a short period swell, just 6 seconds, and the combined energy is only 89 (weak), so it’s not going to be powerful, but it’ll be clean. The afternoon holds up with glassy conditions again, but a tad smaller at 3ft. It’s surfable, but very ordinary.
There’s a few days after that where the wind stays glassy or cross-off, but the swell is tiny, often under 3ft, and the energy is weak. The water temp anomaly is normal, so no surprises there.
Now, far out on the 26th of August, a Wednesday, the models are showing a big spike. That morning we’ve got a 5ft NE swell with a cross-off SSW wind, energy of 309 (moderate), but it’s still marginal. But the real standout is Wednesday afternoon: a huge 10ft NNE swell, with a cross wind from the south at 12 mph. The energy is absolutely pumping at 1675 (strong to very strong). The problem is, that’s too big for this break, especially for beginners. This is expert territory only, and even then, the short period of 8 seconds and the cross-chop will make it a wild, challenging session. Worth watching if you’re a charger, but not a day for the average crew.
Then on the 30th of August, a Sunday morning, we get another 10ft pulse, this time from the SSE with a longer 11-second period. The energy is a massive 1735 (very strong). Again, this is too big for Denhams, and the wind is onshore from the ESE, so it’s going to be a mess. The afternoon drops to 8ft, still too big and onshore. For the experienced locals, maybe a novelty, but it’s not a user-friendly day.
So, honestly, if you’re looking for a good, clean, rideable wave, circle Sunday the 16th of August morning. After that, it’s a long wait for the big, unruly, late-month swells. For the rest of the time, the forecast is a bust. Sometimes it’s just like that around here.

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.
