The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles.
First up, Denhams Beach. This is a beginner-friendly spot, very consistent, and it’s mostly exposed to an east-southeast swell. The water is sitting at 63°, which is a touch warmer than normal for this time of year – nothing crazy, but notable.
The good news is, there’s actually a bit of a pulse coming through, but the timing is everything. The first real highlight is Monday afternoon, August 11th. The wind swings offshore from the WNW, with a light breeze, and the swell is a clean 3ft from the ENE with a period of 10 seconds. The combined wave energy is moderate at 146 – not a huge day, but with glassy conditions, it’ll be a beautiful, clean little session. The waves will be weak, but for a beginner or longboard, it’s a real treat.
Then, we have a big gap. Nothing much happens until August 20th. That’s a solid week of small, poor surf. The wind is mostly wrong, or the swell is tiny. It’s a bit of a dry spell.
But then, Thursday morning, August 21st is the standout. The swell bumps up to 5ft from the ENE with a period of 8 seconds, and the wind is glassy – dead calm. That’s rare. The energy is strong at 333, and the water will be clean as a whistle. This is the best session on offer, and it’s going to be a proper fun morning. The swell is a bit too big for beginners, but for anyone with a bit of experience, it’s a goer.
Friday afternoon, August 22nd is also solid. The swell holds at 6ft from the ENE, period 9 seconds, and the wind is cross-off from the NNW with a gentle breeze. The energy is pumping at 496. It’s going to be clean, powerful, and punchy. A bit more size, so it’s for the confident crew.
Saturday morning, August 23rd rounds out the run. The swell is 6ft from the ENE, period 10 seconds, with offshore wind from the west. The energy is strong at 631. This is a classic, clean morning session. Another one for the intermediate and above.
The very end of the forecast gets messy. Strong winds and rain on the 24th and 25th will blow it out, so get your waves on the 21st, 22nd, and 23rd. That’s the window.
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.
