The Lowdown
Alright, Rusty here again, but this time in feet and knots for those who think in the old numbers. Lookin’ at Denhams Beach for the next couple weeks – it starts quiet, but we’ve got one real gem.
Saturday the 18th of July is a dud – a tiny 1ft windswell from the east-northeast with nothin’ behind it. Save the wax. Then Sunday morning the 19th arrives, and that’s the session to circle on the calendar.
Sunday morning brings a clean 5ft swell out of the ENE, with a 12-second period – that’s proper groundswell. The water’s about 63°F, which is normal for mid-winter. Wind is dead glassy from the north-northwest. This is as clean as it gets for this beach. The swell energy is moderate (616). It’s beginner-friendly at that size and the conditions are about as good as it gets. The direction isn’t the absolute best for the spot, but you won’t care once you’re out there.
Monday morning the 20th is another good one – glassy winds again, wave height around 6ft, and a solid 667 energy reading. Another cracker if you missed Sunday. The afternoons get a bit bumpy, so go early.
Tuesday the 21st stays clean with 4ft to 5ft waves and glassy conditions. Then it all fades. From Wednesday the 23rd through to Tuesday the 29th, it’s mostly flat or tiny – a long stretch of poor to useless surf. You’re lookin’ at nearly a week with waves below 2ft and weak energy.
We get a tiny glimmer on Wednesday morning the 29th – a 3ft south-southeast swell with a short 6-second period and clean offshore wind. Surfable but nothing special. Thursday the 30th morning offers 4ft from the south, but at only 5 seconds, it’s weak and won’t hold shape.
The first of August brings heavy rain and 30 km/h onshore winds – stay on land. Sunday the 2nd of August glassy in the morning, but the swell’s only 4ft at 8 seconds. Ordinary.
Bottom line: Sunday morning, July 19th – that’s your winner. Clean, glassy, 5ft, with good energy. Monday morning is a close second. The rest of the run is for checkin’ the tide pools.
Rusty out.

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.
