The Lowdown

Alright folks, it's Rusty. Let's be real about what's on the table for the next couple of weeks. Right now, we’ve got a bit of a wait ahead of us. The forecast shows a long stretch of pretty average conditions, so grab a coffee and settle in.

The first real chance of anything surfable kicks off on Sunday the 27th of July, but even then, it's only a marginal call. The sea temperature is a staggering 7°F warmer than usual for this time of year, making it feel like a warm bath out there, but that's about the only positive.

The main focus, and really the only spot in the game, is Deadman's. For the first few days, the swell is small, around 3ft to 4ft, coming from the SW. That's a long-period groundswell of 18-19 seconds, which is full of energy—the combined energy reading hits 731 at one point—but the wind is the problem. It's a stubborn cross-onshore breeze from the WSW, making everything choppy and lumpy. There's nothing to get excited about here.

Things don't improve much as we head into the new week. Monday morning sees a 3ft SW swell with the same cross-onshore wind. It's just not clean.

Tuesday the 28th of July is worth a mention because the morning sees the wind drop to a light breeze, becoming a cross-shore. The swell is still a modest 4ft from the SW (18s period), with a combined energy of 877. It's not perfect, but for the first time in the forecast, you might get a few clean-ish ones. The crowds are listed as "often" here, so don't expect to have it to yourself.

Then we hit a real shift. From Wednesday the 29th of July afternoon, the swell direction swings to the WNW and the period drops to just 8 seconds—that's short-period, wind-affected slop. The height jumps up to 7ft by Thursday morning, but it's a messy, onshore wind trend. The water's going to be a washing machine. Any surf from this point is for the hardcore only, and honestly, the setup looks more interesting for kite surfing than paddle surfing.

The entire first week of August is a write-off for quality. The swell hangs around 3ft to 5ft, still from the WNW with short periods, and the wind stays cross or cross-onshore. The energy levels are moderate, with values like 420 or 240, but it's all just poor surf conditions. There's no standout session here.

Saturday the 9th of August morning shows a glimmer of hope with a 5ft WNW swell (10s period) and a gentle cross-shore breeze. The combined energy is 388, which is moderate. It's a "marginal" call, which is much better than "poor," but it's still a long way off.

The closest thing to a standout comes on Monday the 10th of August morning. The swell is 5ft from the WNW with a 10-second period, and the wind finally drops to a light cross-shore breeze. The combined energy reads 480. It's the best wind and swell combo in the entire 16-day window. Don't expect perfection, but it's the only window where you might find a few clean, rideable waves.

So, to wrap it up: the first real surfable day is Sunday the 27th of July, but it's poor. The best bet is Tuesday the 28th of July morning for a few clean-ish ones, or Monday the 10th of August morning for the best overall conditions. For the rest of the time, it's a lot of waiting for something that just isn't going to happen. Keep an eye on the forecasts, though—it never stays flat for good.

Rusty.

Information about the Deadman's Surf forecast

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