The Lowdown
Alright, Rusty here. Grab a coffee and let’s look at what’s coming up for Puerto Viejo over the next couple of weeks.
First up, we’ve got a solid little pulse arriving on Tuesday, August 18th. It’s not massive, but it’s clean. Morning sees a 6 ft SW groundswell with a 13-second period, and a light S offshore breeze. The water is sitting right around average for the time of year. That combo is going to peel nicely down the point. The afternoon bumps up to 6 ft SW with a 12-second period, still holding that S offshore wind. The combined energy reading is 1108 (moderate), which feels punchy and fun. This is your standout window—clean, lined up, and very surfable.
Wednesday, August 19th, keeps the momentum going. Morning is 5 ft from the SSW with a 10-second period and a light cross-offshore breeze, so the face stays clean. Afternoon drops slightly to 5 ft with a shorter 9-second period, but still a gentle offshore wind. It’s a good day, but the Tuesday window has a little more juice and consistency.
Thursday, August 20th, gets a bit tricky. Morning is 5 ft SSW but the wind swings cross-shore from the WNW, putting some ripples on the face. The energy drops to 429 (weak). Afternoon improves as the wind goes cross-offshore, but the swell backs down to 4 ft. It’s rideable but not the pick.
From Friday, August 21st, through to the end of the month, the surf drops right off. We’re looking at ankle-to-knee-high leftovers, mostly under 2 ft, with a few tiny pulses from the SW. The energy readings are all below 300 (weak). The wind is often light and clean, but there’s just no power. Friday the 21st is the first proper lull, and it stays quiet for over a week. This is a proper gap in the surf.
The first real sign of life after that lull shows up on Friday, August 28th. The morning bump is 3 ft SW with a 17-second period, combined energy 775 (moderate), and glassy conditions. Afternoon builds to 4 ft SW at 16 seconds, energy 861. That’s a long-period groundswell, so it’ll wrap nicely into the point and reef setups. The wind is light cross-offshore. This is the second standout, but it’s a week and a half away—so keep an eye on it, but don’t lock in plans yet.
Saturday, August 29th, has a solid 5 ft SW with a 15-second period, but the morning is cross-shore from the WNW, which puts a bit of texture on it. The afternoon cleans up with a cross-offshore breeze, and the energy hits 1026. That’s a good call for the afternoon session.
Sunday, August 30th, settles back to 4 ft SW with a 13-second period, clean and light winds. It’s a fun, mellow day. After that, through the start of September, we’re into smaller, slower waves—more for the longboard or a quiet cruise.
The best of the whole window? Tuesday, August 18th, especially the afternoon. That’s the one where the swell, wind, and period all click. Friday, August 28th, is a promising runner-up, but it’s further out and less certain.
Signing off,
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.
