The Lowdown
Alright folks, Rusty here with a look at what’s coming down the line for the next couple of weeks. The Rock-Costa Azul is an exposed reef break, dialled for advanced surfers, and it’s about to get a proper taste of the Southern Ocean. The water temperature is sitting at 86°, a full 4° warmer than usual for this time of year – that’s a solid anomaly and feels more like a tropical bath than a typical winter dip.
The big news is Wednesday the 29th. We’ve got a powerful groundswell rolling in, straight out of the SSE, pushing a solid 5ft worth of energy. This isn't just any swell; the combined wave energy is a massive 1704, which is strong and full of grunt. The period is a long 16 seconds, meaning those waves will have serious shape and juice. To top it off, the wind goes glassy in the morning and swings to a clean offshore from the WNW in the afternoon. This is the standout of the entire forecast – excellent conditions for those with the skill to handle it. This swell is too big and powerful for beginners.
By Thursday the 30th, the swell drops a notch to 4ft, but the period stays long at 14 seconds. Morning winds are a bit cross, not ideal, but the afternoon cleans right up with a moderate WNW offshore. It’s still a good day, just not the same beast as Wednesday.
Friday the 31st sees the swell fade to 3ft. The winds are a bit messy – cross-onshore in the morning and a stiff cross-offshore later. The combined energy drops to 406, so it’s much weaker. It’s surfable but nothing to race for.
Saturday the 1st of August is a write-off with poor conditions and a weak, sloppy 3ft swell. A risk of thunderstorms in the afternoon doesn't help.
Sunday the 2nd is a surprise recovery. The swell is tiny at 3ft, but the morning is glassy, and the wind goes moderate offshore in the afternoon. The combined energy is down at 268, but for a small wave log or a longboard, those glassy conditions make it a fun, clean session.
From Monday the 3rd through to Tuesday the 11th of August, it’s a long run of small, weak surf. The swell hovers between 1ft and 4ft, and the combined energy mostly sits under 500. The winds are generally cross-offshore or clean, but there’s just not enough size to get excited. There’s a bit of a spark on the afternoon of Monday the 10th of August, where a very long-period 20-second swell pushes through at 2ft, with a combined energy of 619 and clean winds. That's a tease of good quality but lacking in height.
The second week picks up around Wednesday the 12th of August with a consistent 3ft to 4ft SSW swell and periods staying in the 15-18 second range. Winds are clean in the afternoons, making for some very good, long-period lines. It’s worth checking out if you need a fix, but it’s nothing like that Wednesday stand-out.
So, lock in Wednesday the 29th of July and Thursday the 30th as your best bets. After that, you’ll be waiting a while for the size to come back. Keep an eye on the afternoon of the 10th and the week of the 12th for some clean, small-wave sessions.
Rusty.

Information about the The Rock-Costa Azul Surf forecast
The above surf forecast table for The Rock-Costa Azul provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Rock-Costa Azul can be found by selecting the local surf guide option on the grey menu. Our The Rock-Costa Azul 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 (The Rock-Costa Azul) 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 The Rock-Costa Azul 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.
The Rock-Costa Azul is 13 km (8 miles) from Cabo San Lucas. If you plan a holiday in Baja Sur, look for hotels and other accommodation in Cabo San Lucas. Cabo San Lucas has rooms for a wide range of budgets as well as car hire and transport links.
