The Lowdown
Alright, let’s get into it.
Right now, things are pretty quiet out at The Rock-Costa Azul. That’s a reef setup that needs a decent push from the south, and we’ve got some small swell coming through but the timing and winds are off to start. Wednesday and Thursday mornings are a write-off – messy onshore winds and poor conditions. The water’s sitting at a very warm 87°, which is much warmer than normal for this time of year.
Thursday afternoon shows a bit of life. Clean cross-off wind, a 2ft SSW swell with a long period of 18 seconds, and moderate wave energy (466). That long period means it’ll have some push and shape, but at a reef break like this, it should wrap in nicely. Still, it’s not the standout.
Friday afternoon cleans up again, with 3ft from the SSW at 17 seconds and moderate energy (577). The wind is light cross-off, so the face will be tidy. The real highlight though is Saturday morning. That’s the one. Glassy conditions, 4ft of SSW swell with a solid 16-second period, and strong moderate energy (670). It’s not huge, but it’s clean, lined up, and at a reef break like The Rock-Costa Azul, that’s going to produce some nice, rippable waves. Crowds are likely here, so get in early.
Sunday looks a bit more mixed – some clouds, cross-shore winds, and dropping energy. Monday morning brings another window of opportunity: glassy again, with 2ft of long-period SSW swell at 20 seconds and moderate energy (532). That’s a very clean, low-stress session for the experienced surfer. Small but super clean.
Tuesday and Wednesday mornings are compromised by onshore or cross-onshore winds. Wednesday afternoon has a risk of thunderstorms, but the wind goes cross-off, so if you time it between showers, there’s 3ft of SW swell at 16 seconds (energy 413) to play with.
Looking further out, Thursday afternoon on the 13th looks promising – 3ft SSW swell at 20 seconds, very clean cross-off wind, and strong moderate energy (919). Then Friday afternoon on the 14th is the big standout of the whole forecast. The swell pushes up to 5ft from the SSW at 16 seconds, with glassy conditions and strong energy (1056). That’s excellent for experienced surfers. The Rock will be working well.
After that, Saturday the 15th holds 5ft in the morning but with cross-on wind, so the afternoon cleans up again with 4ft and cross-off. Sunday the 16th starts glassy with 4ft of SW swell, then gets a bit messy. The second week sees smaller swells and more onshore or cross-shore winds, so the quality drops off. Nothing major to get excited about after the 14th.
Overall, the best bets are Saturday morning the 8th for a clean, fun session, and Friday afternoon the 14th for the biggest, cleanest swell of the period.

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.
