The Lowdown
Alright, this is Rusty, coming to you live from the Puertecillo coast. Let's get into it, mate.
We've got a bit of a mixed bag over the next couple of weeks, but there are a couple of clear windows where it all comes together. It starts off a little average, but if you're keen to wait for the real juice, the end of the month is looking like it'll be the main event.
Tuesday the 18th kicks it off with a 4ft SW groundswell with a solid 16-second period. The energy is there, pushing 1297 (moderate energy), but a cross-shore wind is messing with the surface. It's a bit scratchy. The afternoon picks up to 5ft, but the wind jumps to 19 mph, turning it into a lumpy, cross-chop mess. Not the one.
Wednesday the 19th is where we see a shift. The morning swell is up to 7ft from the SW, but it’s still a bit bumpy. The real standout is Wednesday afternoon. The wind drops to glassy, dead calm, and the swell is a clean 7ft from the WSW, with a good 14-second period. That's the kind of session you wait for. The energy is strong at 1855, and for an advanced, very consistent point break, this is prime. The water temp feels about average for this time of year, so you won't be too shocked.
Thursday the 20th and Friday the 21st are more of a challenge. The swell drops and the cross-wind returns, making it messy and weak. By Saturday the 22nd, the swell bottoms out to 3ft with a poor period, so the energy is weak (413). It's not worth paddling out for.
We then hit a real flat spot. From Sunday the 23rd through to Monday the 24th afternoon, the swell is small and the winds are all over the place. Tuesday the 25th is small and weak, and Wednesday the 26th morning is still average with rain around.
Now, hold on to your board. Wednesday the 26th afternoon is another golden window. The wind swings offshore (cross-off), and we get a 5ft, 12-second WSW swell with a strong 1069 energy reading. It's clean. Then, Friday the 28th morning is an absolute winner. Glassy conditions again, with a clean 5ft, 15-second groundswell from the WSW. That's a proper long-period groundswell, perfect for this point break, with 1319 energy behind it. This is my top pick for the next week.
The last weekend of August is for the brave. Saturday the 29th morning has a big 10ft, 13-second WSW swell, with clean, offshore wind. But at that size, it's expert-only territory. The energy is massive at 2969 (very strong). Sunday the 30th stays solid at 8ft, but the wind is more cross-shore, making it less clean.
As we roll into the start of September, Monday the 31st afternoon has a chance to be good with a glassy 6ft swell. But the real highlight in the second week looks like Tuesday the 1st of September. The afternoon shows a big 8ft SW swell, with light onshore wind. The energy is huge at 2369, but that size with onshore wind is going to be a battle. Then Wednesday the 2nd of September morning keeps it solid at 7ft, but the cross-wind will be a factor.
So, to sum it up: for the cleanest, most fun waves, get in the water on Wednesday the 19th afternoon or Friday the 28th morning. Those are the two standouts. Everything else is either too small, too windy, or too big for the average surfer.
Rusty, signing off.

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