The Lowdown
Alright, Rusty here again. Let's talk about Costa Azul in feet and Fahrenheit for the crew that thinks that way.
The early part of the week is pretty marginal, with some small, weak swell and iffy conditions. Sunday the 13th is a write-off – tiny waves and tricky winds. Monday the 14th isn't much better, a little clean but still on the small side. We're basically waiting for things to settle down and the ocean to find its rhythm.
Now, Tuesday the 15th afternoon is where it gets interesting. The wind goes completely glass – dead calm. That's a major positive, it'll be like a mirror out there. We've got a 2ft SW groundswell (period 16 seconds) rolling in. The combined energy is a solid moderate (566). It's not big, but with zero wind and that long period, it'll be clean, lined up, and perfect for a longboard or a funboard. This is a great little session for the intermediate crew.
Wednesday the 16th morning keeps the good vibes going with glassy conditions again. The swell has picked up a touch to 3ft from the SSW, still with a nice 16-second period. Energy is ramping up to 603. This is the start of a nice consistent run.
Thursday the 17th is a standout. Morning glass, 4ft SSW swell at 14 seconds. Energy is getting strong at 829. This is clean, punchy, and with that period it'll have some proper shape. It's right in the sweet spot for intermediates. The afternoon holds clean too.
Friday the 18th has a bit of a cross-onshore breeze in the morning, but the afternoon cleans right up again with a cross-offshore flow. Solid 2-3ft swell with a very long 19-second period. Energy is strong (724). That long period means longer waits between sets, but the waves that come through will have some serious push. Best on a reef or point, but it'll be fun.
Sunday the 20th is another good one. Morning sees a clean 4ft SW swell (833 energy) with a cross-off breeze, and the afternoon goes offshore from the NW with the same size. Clean, fun, consistent.
Monday the 21st morning is glassy again. This is a beauty. 4ft SW swell, 17-second period. Energy is cranking at 933. This is the pick of the forecast for me. Clean, good size, long period groundswell. It's not huge, but it's perfect for an intermediate surfer. A real joy.
The rest of that week into the next weekend holds some fun, clean options. Tuesday the 22nd is glassy in the morning with another 4ft SW swell. Thursday the 24th is glassy all day. Friday the 25th and Saturday the 26th both have glassy starts with clean afternoons. The swell does ease off a touch, but the quality stays high.
Then, look at Sunday the 27th. Dead calm, glassy conditions, 2ft SW groundswell with a 17-second period. Energy is strong again (517). That's a long-range standout that's promising but less certain. And Monday the 28th caps it off with a glassy 3ft SSW swell. The second week looks like it'll deliver some more of those clean, long-period gems.
The water temp is about average for the time of year, so you won't need a full winter suit.
So, if I had to pick just one or two standouts: Thursday the 17th morning for the clean, building swell, and Monday the 21st morning for that glassy, 4ft perfection. Get out there.
Rusty.

Information about the Costa Azul Surf forecast
The above surf forecast table for 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 Costa Azul can be found by selecting the local surf guide option on the grey menu. Our 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 (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 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.
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.
