The Lowdown
G’day, Rusty here. Lookin’ at the next couple of weeks for Puerto Viejo – it’s a slow burn, but there’s a serious pulse comin’ right at the end of August that’ll get the blood pumpin’. The first week or so is mostly small and ordinary, so don’t expect much until we hit that Friday the 28th of August. That’s the real standout.
The water temp’s sittin’ about average for the time of year, so no need to dig out the 5/4 just yet.
Let’s start from this Thursday morning, the 20th of August. It’s a mixed bag – clean cross-off winds in the afternoon with a 4ft SSW swell, but the morning’s got a bit of cross-shore chop. Thursday afternoon is the pick of the early days, with clean lines and moderate energy (351). Still, it’s nothin’ to write home about.
Friday the 21st and Saturday the 22nd drop right off – tiny waves, 3ft to 1ft, with weak energy (down to 135). The winds are clean, but the swell’s just not there. Sunday the 23rd sees a bit of a pulse, but it’s still small – 1ft with a long 16-second period, but the energy’s weak (160). Offshore winds keep it clean, but you’ll be huntin’ for a wave.
Monday the 24th and Tuesday the 25th are more of the same – tiny, weak, and only a few knee-high dribblers. The energy’s mostly under 100, so honestly, it’s a bit of a flat spell.
Then Wednesday the 26th and Thursday the 27th show a little life – clean cross-off winds and a building swell. Thursday afternoon the 27th has a 2ft WSW groundswell with a 20-second period, and energy’s up to 453. It’s clean, but still small.
Now here’s the money shot. Friday the 28th of August – that’s the one. Morning sees 5ft SW groundswell with a 17-second period, and the energy’s cranked up to 1356. The wind’s near glassy, cross-off, and the waves are clean. Afternoon gets even better – 6ft SW, 16-second period, and energy’s at 1571. This is proper, powerful groundswell – best for the point and reef sections at Puerto Viejo, where those long lines will reel. The break is a point-and-beach setup, so the point will handle that long period nicely. This is for experienced surfers only – over 5ft, so beginners should sit this one out. Crowds are often, so expect company.
Saturday the 29th of August holds solid – 5ft SW in the morning, clean cross-off, then 5ft SW in the afternoon with offshore winds. Energy’s still strong (1045 and 945). This is another great day, but the Friday is the standout.
From Sunday the 30th of August onward, the swell fades. Monday the 31st has a bit of cross-on wind in the morning, but the afternoon cleans up with 4ft SSW and offshore breeze. The first few days of September are small again – 2ft to 4ft, with clean conditions but not much push. The 2nd and 3rd of September have some moderate energy (up to 633) and long periods, but it’s back to knee-high territory.
So bottom line: the first week is a write-off unless you’re desperate. The real action is Friday the 28th and Saturday the 29th of August – that’s your window. Get it while it’s hot.
Rusty.

Information about the Puerto Viejo Surf forecast
The above surf forecast table for Puerto Viejo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Puerto Viejo can be found by selecting the local surf guide option on the grey menu. Our Puerto Viejo 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 (Puerto Viejo) 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 Puerto Viejo 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.
Puerto Viejo is 11 km (7 miles) from Mala. If you plan a holiday in Lima, look for hotels and other accommodation in Mala. Mala has rooms for a wide range of budgets as well as car hire and transport links.
