The Lowdown
G'day, Rusty here. We've got a solid 16-day window for Maitencillo, a river mouth that handles a SW swell real well. The water's sitting at 54.5°, which is about average for this time of year in Chile – nothing unusual. The first few days are a mixed bag, but the second half of the month and into August fire up nicely.
Sunday the 19th kicks off with a clean 5.2ft W swell, 11-second period, and a light cross-off breeze from the S at 3 mph. Combined energy is 844 – moderate, but the waves are well shaped and glassy. A good start for beginners, though that 5.2ft is getting a bit punchy for the absolute newbies. Monday the 20th drops a little to 3.6ft, still clean, but the energy fades to 456. Tuesday the 21st is a write-off – tiny 2.0ft swell and rain, with only 137 energy – not worth paddling out.
Then Wednesday the 22nd morning is a standout. The swell jumps to 7.5ft from the W, 11 seconds, with glassy conditions and a combined energy of 1338. That's moderate-to-strong energy, and the waves are excellent for experienced surfers – a bit too much for beginners, but if you're comfortable in overhead surf, this is prime. The afternoon gets a light cross-on, still okay but not as clean.
Thursday the 23rd drops back to 3.9ft, glassy morning, but energy is only 420 – a mellow session. Friday the
Short Range ForecastHeavy rain (total 70mm), heaviest during Tue morning. Very mild (max 15°C on Mon afternoon, min 11°C on Sun night). Winds increasing (calm on Sun night, strong winds from the N by Tue morning). | Days 4-6 Weather SummaryMostly dry. Very mild (max 19°C on Fri night, min 13°C on Thu morning). Wind will be generally light. | ||||||||||||||||||||

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