The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming down the line for our patch.
To be straight with you, the next week and a half is looking pretty lean. We’ve got a long stretch of small, weak, and messy conditions before anything really wakes up. The first real surfable day is Monday the 7th of September, but even that’s just a marginal pulse. You’ll be waiting nearly until the end of the 16-day window for the standout.
The water temperature is sitting at 63°, which is a touch warmer than normal for this time of year, so that’s a small comfort.
Let’s break it down.
Saturday the 5th and Sunday the 6th are a write-off. Tiny, weak swell, with poor surf conditions. Not worth paddling for.
Monday the 7th of September sees a bit of a bump in the afternoon – a 5ft SSE swell coming in at 8 seconds, with moderate energy (296). It’s still marginal, with a cross wind, so it’s more of a hope than a plan.
Tuesday the 8th of September morning is the first real decent window. The swell drops to 4ft from the SE, but the period is 9 seconds, so it’s got a bit of shape. The wind is glassy – light and offshore. That’s clean. The energy is moderate (179). For a beginner-friendly spot like Denhams Beach, this is as good as it gets for a while. It’s small, clean, and very consistent.
After that, it’s back to tiny, weak, and ordinary conditions for the rest of the week and into the next. Days of 0.7ft swell with long periods, cross-onshore winds, and zero energy. Not worth a mention.
Then we get a real spike right at the end of the forecast. On Thursday the 17th of September, a big 12ft SSE groundswell hits, with a long 13-second period. The energy is massive – 4197 (morning) and 5321 (afternoon). The wind is light, so the surface will be clean enough. But here’s the thing – that is way too big for Denhams Beach. 12ft is expert territory only. For a beginner spot, this is a no-go. It’s just too much power. The setup looks more interesting for kite surfing than paddle surfing.
The swell eases a bit on Friday the 18th, still 10ft in the morning, then 8ft in the afternoon with a strong cross wind, so it’s lumpy and messy.
Saturday the 19th sees the swell drop to 5ft SE in the morning, period 11 seconds, with moderate energy (612), but the wind is cross, keeping it average. The afternoon picks up to 8ft, but it’s cross-onshore and choppy.
So, the real standout? Tuesday the 8th of September morning. It’s the only time in the whole 16 days where the conditions line up for a clean, small, fun session at Denhams Beach. It’s a beginner-friendly spot, very consistent, so if you’re just getting into it, that’s your window. The 4ft SE swell with glassy conditions will be pure fun. Get on it, because the rest of the run is a waiting game.

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.
