The Lowdown
Alright, this is Rusty talkin' from the banks of La Bocana. Right now, it's a bit sleepy, but there's some fire on the horizon if you're willin' to wait.
We're startin' with a slow patch. The surf on offer is pretty weak, with a small SW swell. The water's a warm 86°, right where it should be for this time of year. The real fun doesn't kick in until the morning of Thursday, the 29th of August.
Here's the breakdown. Monday the 17th is a bust with a cross-on wind messin' up a 4ft SW swell. Not worth your time. Tuesday morning the 18th is the first little tease – the swell is still 4ft, but it's glassy with that 14-second groundswell. Clean conditions, but the energy is just moderate (521). It's a little inconsistent, but it's a good warm-up.
Wednesday morning the 19th is another clean look. A 3ft SSW groundswell (15-second period) with a light offshore from the NNE. This is your best bet in the first week for some proper shape. Energy is moderate (519) and you'll likely have it uncrowded since it's not a packed spot. Keep in mind, this is a river mouth, so it can be hit or miss.
Then we hit a lull from the 20th through the 27th. Plenty of glassy mornings, but the waves are tiny – between 1ft and 3ft – with weak energy. The 24th has a long-period (18 seconds) SSW swell, but at 2ft, it's just not enough to get stoked about. Friday the 28th of August is the turnin' point. The morning is clean and glassy with a 3ft SW swell, but the energy jumps to strong (651). This is the appetizer.
The main event is the morning of Saturday, the 29th of August. Circle this one. A 5ft SSW groundswell with a long 17-second period, glassy conditions, and strong wave energy hittin' 1485. This is big, solid, and clean – but at 5ft, it's expert territory. A point or reef would handle this long-period energy better, but La Bocana is a river mouth, so it might offer some protection. Sunday the 30th is a close second, with another 5ft SSW swell and glassy conditions in the morning. Very strong energy (1180), and for the confident surfer only. The energy drops off through Monday the 31st and into September as the swell fades.
So, to wrap it up: the wait is long, but the payoff at the end of August is heavy. Get ready for a real session on the morning of the 29th if you've got the guts. Wednesday the 19th is a fun, clean option for the patient surfer.
Rusty.

Information about the La Bocana Surf forecast
The above surf forecast table for La Bocana provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at La Bocana can be found by selecting the local surf guide option on the grey menu. Our La Bocana 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 (La Bocana) 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 La Bocana 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.
