The Lowdown
Alright, grab your boards, let’s talk about what’s on offer at The Rock-Costa Azul. This is a consistent reef break that handles swell well, and it’s got a few windows of opportunity over the next couple of weeks. The water’s sitting at a very warm 89°F – that’s much warmer than usual for the time of year, so you’ll be comfortable in just boardshorts or a springy.
For Sunday the 23rd, I’d say give the water a miss. It’s a bit messy with cross-shore winds and weak 2 to 3 ft swell from the SSW, and the energy is weak. It’s not really worth paddling out.
Monday the 24th morning stays marginal with that SSW swell around 5 ft period only 10 seconds, and a cross-onshore breeze. But hold on – Monday afternoon looks like a real window. Swell holds at 5 ft from the SSW, period bumps to 12 seconds, winds go clean cross-offshore, and the combined energy ticks up nicely (1082). That’s the best session of the early days and it’s a solid option for experienced surfers.
Tuesday the 25th afternoon is pure glass. The swell drops to 2 ft SW with a long 16-second period. It’ll be small but glassy and clean – if you’ve got a bigger board, it could be fun and uncrowded, though this spot can get crowded sometimes.
The rest of that week is a bit of a mixture. Wednesday and Thursday are poor or very marginal. Friday the 28th afternoon picks up: 5 ft SSW at 17 seconds, clean cross-off wind, energy cranking to 1579. That’s another standout morning or midday session for the experienced crew.
Saturday the 29th afternoon stays clean but the swell’s easing. Still, the offshore flow keeps things lined up.
Now, the real juice arrives on Monday the 31st of August. Morning glassy conditions, 6 ft of SSW swell at 13 seconds, and energy up at 1475. This is the pick of the first week: glassy and punchy, and it’s a day for advanced surfers to get excited about.
Tuesday the 1st of September afternoon – this one’s a beast. The wind drops to 0 mph, absolute glass, and the swell jumps to 8 ft from the SSE at 13 seconds with energy at 2642. This is expert territory – too big for beginners, but for the crew who know the reef, this could be the best session of the whole forecast. Keep in mind, it’s over a week away, so there’s some uncertainty, but it looks promising.
Wednesday the 2nd September and Thursday the 3rd get blown out with strong onshore winds and messy conditions. The swell’s still big, but the quality is poor.
Friday the 4th September morning: the swell is 12 ft from the SSW with a 14-second period, and the combined energy is massive at 5644. The wind is onshore, but the report says tide and wind are favorable – even so, 12 ft is huge for this break. Only for top-tier experts, and it’s a real risk. The afternoon stays similar.
Saturday the 5th September is still sizeable but dropping, and winds improve a little. Not my top pick.
Sunday the 6th September morning: 8 ft SE swell at 11 seconds, light offshore wind, and clean conditions. Energy is 3179. That’s a good session but the period is shorter. By the afternoon it’s 10 ft – too big for many.
Monday the 7th September is a monster. 16 ft to 23 ft SE swell, glassy morning but with a very long 14-second period, and energy numbers go through the roof – 42951 for the afternoon. This is extreme, dangerous, and only for the most experienced big-wave chargers. For everyone else, sit this one out on the beach.
The best windows overall? Monday afternoon the 24th August and Monday afternoon the 31st August stand out as excellent, clean sessions with good shape and energy. Tuesday 1st September afternoon is another top-tier call but only for experts. The second week has more size but also more risk.
Stay safe out there, and don’t get caught inside on the 7th.

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.
