The Lowdown
Howdy, Rusty here. Let’s chew the fat on what Deadman’s is serving up.
I’ll level with you – this forecast is a grind. Over the next 16 days, there’s a big gap of nothing good from Thursday the 23rd until Wednesday the 29th. The swell is tiny, and the wind is a nasty cross-onshore, kicking up choppy, poor conditions. You’d be wasting your time and energy.
The water is sitting at 62°F, which is a whopping 5°F warmer than what’s normal for this time of year. That’s a real oddity, so you might be able to get away with a springsuit.
The first flicker of hope comes on Thursday the 30th of July in the morning. The swell bumps up to 7ft from the NW, but the period is a short 8 seconds. That’s a windswell, so it’ll be a bit messy and lacks that long, clean push. The wind is a light cross-shore from the SW at 9 mph, which is the best we’ll see, but it’s still not glassy. The combined energy is a strong 1323. This is an advanced spot, and with that size, it’s for experts only. Beginners, don’t even think about it. For a stand-out, this is it, but it’s a marginal call. The swell direction (NW) is a perfect match for the spot’s optimum (NW), but that short period means the waves will be a bit crumbly. It’s a beach and reef setup, so if the wind picks up, the kites will be having more fun than the paddlers.
After that, from Friday the 31st of July onward, the swell drops to 5ft and smaller, with that same short period, and the wind stays cross or cross-onshore. The energy drops to moderate. The best mornings will be the light wind days, like Saturday the 1st of August and Sunday the 2nd of August, with winds at just 6 mph, but the swell is weak. There’s a slight bump on Monday the 3rd and Tuesday the 4th of August, with swell hitting 6ft and the period stretching to 10-11 seconds, with moderate to strong energy (516-690). The wind is cross-shore, so it won’t be clean, but it’s the best-looking stretch in the second week. Still, nothing is a real standout.
Bottom line: it’s a rough run with only one day that’s even worth a look, and that’s a maybe. If you’re itching, the morning of the 30th of July is your only play, but don’t expect magic.
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.
