The Lowdown
Alright, let’s get into it. The Rock-Costa Azul is a reef setup that’s consistent and mainly for advanced surfers. The water’s sitting at a toasty 87°, which is much warmer than usual for this time of year – feels like a bath out there.
The first few days are pretty average. Wednesday morning has a 3 ft SW swell, but the wind is cross-on and light, so the surface is a bit messy. The energy is moderate (601). The week remains a bit of a slow burn with small, cleanish afternoons, but nothing worth getting excited about.
Friday afternoon is where things start to turn. The swell jumps to 5 ft from the SW with a long 17-second period, and the wind swings cross-off – that’s clean. The combined energy bumps up to a strong 1221, and conditions are looking excellent. That’s the standout session of the first week.
Saturday morning holds similar size at 5 ft, but with a cross-on breeze, so it’s not as clean. By Saturday afternoon, it’s back to cross-off and 4 ft SSW, with solid energy (852) and very good conditions. Sunday morning is glassy, with light S winds and 4 ft SSW swell – that’s a real treat for the early crew.
Monday afternoon sees another good window, with a 4 ft SSW swell, 16-second period, and cross-off wind. Clean conditions again. The energy is moderate (700). By Tuesday and Wednesday, the swell drops back to 3 ft, and the afternoons stay clean but smaller.
There’s a bit of a dry spell from Thursday the 20th through to Saturday the 22nd, with swell dropping to 2 ft and mostly onshore or cross-off winds. The energy is low (200–300 range). A few clean sessions pop up, but it’s pretty weak.
Then Sunday the 23rd afternoon gets interesting again. The swell bumps up to 4 ft but from the SSE, with a short 10-second period – that’s a bit different. The winds are cross-off, and the energy hits 634. Monday the 24th morning sees 5 ft from the SSE with a light cross-shore, and the afternoon is offshore with a light WNW wind, 5 ft and clean. That’s a solid day for the experts.
Tuesday the 25th keeps 5–5 ft, but the morning is cross-on, afternoon cross-off. The direction swings S to SSW. The energy is high (952). Wednesday the 26th morning is onshore with 4 ft SW, but the afternoon brings 6 ft SW with a 14-second period, strong energy (1456), and onshore wind – a bit of a mixed bag. Thursday the 27th morning is onshore, 4 ft SW, but the afternoon is glassy with 5 ft SW and 16-second period, and the energy is strong (1193). That’s a cracking end to the outlook, excellent for the crew that can handle it.
So the real standout is Friday 14th afternoon, with that glassy 5 ft SW groundswell, and then Thursday 27th afternoon with the glassy SW swell. Both are top-tier for the advanced surfer.

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.
