The Lowdown
Right, let’s get into it. We’re looking at a 16-day window that starts small, builds to a proper beast, then settles down again. The spot is The Rock-Costa Azul (Costa Azul)—a reef break that doesn’t mess around when it decides to fire.
First up, the water’s sitting at 88° right now, which is well above the norm for this time of year—we’re talking more than 5° warmer than usual, so you can leave the wetsuit at home.
Friday Morning (Aug 14): Small SSW swell at 0.9m with a long 18-second period, but the wind is cross-on and the tide’s questionable. Not your best bet.
Friday Afternoon (Aug 14): Now we’re cooking. Swell bumps to 1.4m from the SW with a 17-second period, and the wind eases to a light cross-off. Clean lines, proper shape, and that long-period energy is there. This is the pick of the first few days—for experienced surfers, it’s a go.
Saturday (Aug 15): Morning’s average—1.4m but cross-on. Afternoon cleans up nicely, 1.3m from the SSW, light cross-off, very good conditions. Not as punchy as Friday arvo, but still fun.
Sunday (Aug 16): Same pattern—morning bumpy, afternoon clean at 1.2m. Easy wave for a session.
Monday (Aug 17): Morning’s messy, afternoon cleans up at 1.2m with an 16-second period. Consistent but nothing special.
Tuesday (Aug 18): Morning’s a washout, afternoon has a cross-off but there’s thunderstorm risk and the swell’s only 1.1m. Marginal.
Wednesday (Aug 19) to Thursday (Aug 20): Lull. Swell drops to 0.9m, then 0.8m. Mornings are cross-on, afternoons clean but weak. Energy’s in the weak-to-moderate range (380-389).
Friday (Aug 21): Smallest day—0.6-0.7m. Morning poor, afternoon clean but tiny. Not worth the paddle.
Saturday (Aug 22): Morning picks up to 0.9m, clean. Afternoon gets weird—SE swell, cross-shore wind, some chop. Not great.
Sunday (Aug 23): Here we go. Morning has 4.0m of swell with a cross-onshore howl at 25 mph. Afternoon pushes 5.0m from the S with onshore wind. Energy readings are astronomical (6943 and 10500). This is way too big for this break—expert-only, but even then, it’s bordering on reckless.
Monday (Aug 24): Still massive—4.0m morning, 3.5m arvo. Cross-on winds, messy. Same story: too big, too raw.
Tuesday (Aug 25): Swell backs off to 2.2-2.3m. Afternoon has a cross-off that cleans it up, but it’s still big. Experienced surfers only.
Wednesday (Aug 26): This is the gem. Morning has a glassy 1.5m WSW swell with an 11-second period and zero wind—glassy. That’s rare. Afternoon stays clean at 1.4m with a light cross-off. Energy is moderate (841, 779). Keep your fingers crossed for this one.
Thursday (Aug 27): Morning’s 1.1m with cross-on, but afternoon comes alive—0.8m SW swell with a 16-second period, clean. Small but fun.
Friday (Aug 28): Afternoon is the standout—offshore WNW wind, 1.4m from the SSW with a 15-second period, excellent conditions. Energy at 1209. Mark it down.
Saturday (Aug 29): Final

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.
