The Lowdown
Alright, surfers, Rusty here, and I've got the scoop on the next couple of weeks for our little slice of paradise. We’ve got a solid run of surf coming up, so let’s get into it.
This forecast is all about a slow, steady build into some real quality, so don't get discouraged by the smaller stuff early on.
We kick things off on Saturday the 15th with some fun, clean waves. Puerto Viejo is seeing a sweet 4ft swell from the SW with a 14-second period, and the combined energy is a healthy 516. It’s not a monster, but with light cross-off winds, it’s a great way to start the weekend. The water temp here is about average for the time of year, so nothing weird going on.
Sunday the 16th and Monday the 17th are more of the same, with the swell dropping a touch to around 3ft. Don't let the smaller size fool you, the winds are offshore and gentle, so you’ll get some clean, fun lines. It’s perfect for getting a few turns in on a longboard or a fish.
Now, hold onto your board, because Tuesday the 18th is when things get *very* interesting. The swell jumps up, with the morning seeing a solid 5ft from the SW, and the afternoon cranking to 6ft from the SW. With a strong offshore wind blowing, this is the standout of the first week. The energy readings go through the roof, pushing into four figures (1044 in the arvo). This is proper groundswell, and while it’s not too big for experienced intermediates, the 6ft afternoon sets will have your heart pumping. This is the best on offer for the first week, hands down.
We roll into Wednesday the 19th with more clean, offshore surf, but the swell period drops a bit, making it a little less powerful. Still, 5ft to 5ft with clean conditions is a damn good Wednesday.
Then we hit a bit of a lull. Thursday the 20th is still okay in the afternoon, but Friday the 21st through Monday the 24th is a real downer. The swell drops, the winds go cross-shore, and the energy tanks to below 200 on Friday. It’s a few days of flat to tiny, ordinary conditions. Just one of those runs, not unusual for the area.
But wait, there's more. The second week starts to stir on Tuesday the 25th, with a solid 3ft S swell and a nice 12-second period. The wind is light and clean, and the energy is building back up to 272. It’s a promising sign.
The real hero of the entire outlook, however, is an absolute gem sitting way out there. Look ahead to Friday the 28th of August. That morning we get a clean 3ft SW swell, but the afternoon is where it’s at. A 6ft, 15-second SW groundswell rolling in with clean conditions. The energy reading is a massive 1658. This is what we live for. It’s a long-period groundswell, which wants to break a little straighter on the beach, but at Puerto Viejo it’ll find its groove. This is the standout for the whole 16 days, a real “book the day off work” kind of call. It’s a bit distant, so have faith, but the signs are all there.
The next couple of days on the 29th and 30th keep the fun rolling with solid offshore 5ft to 4ft sets. A great way to cap off the run.
So, get on the Tuesday the 18th for a proper session, and for the love of all that is holy, keep your fingers crossed for Friday the 28th. That's the one.
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.
