The Lowdown

Alright, Deadman's has a bit of a mixed bag over the next 16 days, but honestly, it’s mostly a tale of ‘could’ve been.’ The water is running much warmer than normal for this time of year, about 63° at the moment, which is unusual for July.

The first few days are a write-off. Through Thursday, July 16th and Friday, July 17th, we’ve got a moderate cross-onshore breeze messing up a 6ft to 7ft, 8-second wind swell. The combined energy is moderate (543 to 762), but it’s just choppy and poor. Not worth paddling out for.

Saturday, July 18th looks a bit different, but still not good. The swell drops right off to 2ft, but that very long, 17-18 second period from the SW brings a surge of energy (549-646). The wind is cross-shore, so it’s not completely blown out, but the waves are tiny and weak. The swell’s direction is from the SW, which is side-on for Deadman’s optimum NW, so it’s not really wrapping in right.

Sunday, July 19th through to the 23rd is a real lull. Swell hangs around 1ft to 2ft, with a mix of short and long periods. The energy is low (16 to 317), and the wind is either cross or cross-onshore. It’s described as poor or marginal at best. Friday, July 24th shows a spike in period to 24 seconds, but the swell is still only 2ft and the wind cranks up to 19 mph cross-onshore in the afternoon. That’s a lot of energy (797) but it’s going to be lumpy and messy. Honestly, that setup looks more interesting for a kite surfer than a paddle surfer.

Now, the one standout worth keeping an eye on is Saturday, July 25th. The morning shows a 3ft, 21-second swell from the SW, with a gentle cross-shore breeze. The combined energy is massive at 1741, and it has a marginal score. This is a long-period groundswell, so it’ll have proper shape and power, but at a beach and reef break like Deadman’s, that long period can make it break a bit straight. The early morning session could be the pick of the whole 16 days if you’re an advanced surfer, but it’s a week away, so keep an eye on the forecasts.

The tail end from the 26th to the 31st keeps a similar pattern, with 3ft to 4ft swells, mostly from the SW, and persistent cross-onshore winds in the afternoons. The energy is moderate to strong (379 to 1415), but the wind is never fully offshore, so it’s always going to be a little choppy.

Bottom line: Saturday, July 25th morning is the best bet, but it’s a long way out. The rest of the window is either too small, too windy, or both. Deadman’s can be fairly consistent, but this run is a bit of a flat spell with a couple of OK moments.

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.
