The Lowdown
Alright, Rusty here. Let's get into it.
Look, honestly, the next week and a half is a bit of a write-off for Montanita. We’ve got a long stretch of small, weak, and messy conditions starting now. From Monday the 17th right through to about Friday the 28th of August, there’s nothing really worth getting excited about. The swell is tiny, mostly under 3ft, and the wind is either cross-onshore or onshore, keeping things choppy and blown out. The combined wave energy is weak, sitting around 100-200 for most of those days, which is barely enough to push a foamie. There’s a stretch from Saturday the 22nd to Tuesday the 25th where it’s particularly flat, with swell heights dropping to 1ft to 2ft. You’d be better off with a snorkel than a board. Even the water temp is about average for this time of year, so nothing weird there, just a pretty dull run of weather.
The first real glimmer comes on Friday the 28th of August. The morning is still marginal, but by the afternoon the swell picks up to 3ft from the SW with a 16-second period. That’s a proper long-period groundswell, and the energy jumps to 576. The wind is light and onshore, but it’s a step in the right direction. The best hope is Saturday the 29th of August, even though it’s still marginal. The swell is 4ft from the SW and the period is a solid 16 seconds, with strong energy pushing 828. That’s a decent size for Montanita, with some real grunt behind it. The wind is light and cross-onshore, so it won’t be glassy, but it’ll be cleaner than what we’ve had. This is a reef and point setup, so that long-period swell should wrap in nicely, giving some longer rides. It’s an advanced spot, and with the swell just over 5ft, it’s going to be a bit too much for beginners. Crowds are often here, so expect company.
The standout is Montanita on Saturday the 29th of August. The swell is 4ft from the SW, with a 16-second period, and the combined energy is 828. The wind is light and cross-onshore, so it’s a bit of a compromise, but it’s the best we’ve got. The long period means sets will be clean and powerful, but it might break a bit straight on the beach. It’s a reef and point, so it should handle it well. If you’re an advanced surfer, this is your window.
After that, it fades again into the first of September, with small, weak swells and poor conditions. The long-range call on the 29th is promising, but you know how it is – a week out, it’s not locked in.

Information about the Montanita Surf forecast
The above surf forecast table for Montanita provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Montanita can be found by selecting the local surf guide option on the grey menu. Our Montanita 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 (Montanita) 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 Montanita 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.
Montanita is 48 km (30 miles) from Jipijapa. If you plan a holiday in Guayas, look for hotels and other accommodation in Jipijapa. Jipijapa has rooms for a wide range of budgets as well as car hire and transport links.
