The Lowdown

G’day, I’m Rusty. Let’s talk this stretch in feet and degrees Fahrenheit like proper surf talk.

We’re looking at a solid run coming up, but you’ve got to pick your moments. The only spot on the map is The Rock-Costa Azul, and it’s a reef that knows how to handle a good groundswell. The water temp is sitting at nearly 89°F, which is about 6.7°F warmer than it should be for this time of year — that’s not just a little warm, that’s tropical-level weird. Paddle out in boardshorts with no worries.

Sunday the 16th of August afternoon kicks it off with thunderstorms threatening but a sweet cross-off breeze from the southwest at 15 mph. Swell is running around 4 feet from the SSW with a long 14-second interval. That’s a solid groundswell and the energy is reading 604 — moderate, but punchy. Clean faces, expect very good surf conditions.

Monday the 17th is a frustrating day. Morning is a write-off with light cross-on from the SSE at 5 mph and bumpy water. Swell is about 3.6 feet. The afternoon cleans up with a cross-off from the WSW at 12 mph, swell holding 4 feet and a beautiful 16-second period from the SSW. Energy jumps to 706. A good afternoon window but not a standout.

Tuesday the 18th gets better. Afternoon is the call: clear sky, a WNW offshore breeze at 9 mph, and 3.6 feet of SSW groundswell at 15 seconds. Energy at 601. That’s clean, lined up, and offshore — a proper session.

Wednesday 19th morning is a light cross-on, just 3 feet. Afternoon cleans up but stays small. Not a highlight.

Thursday 20th through Saturday 22nd is a slog — small surf, onshore winds or very weak swell. Skip it.

Sunday 23rd has a super long 18-second period but only 2 feet of swell. That’s a clean, tiny groundswell at the reef, maybe fun on a longboard.

Monday 24th through Wednesday 26th is the

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.
