The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cooking for Algarrobo over the next couple of weeks.
The first few days are pretty quiet, with small, weak swell on offer. The water’s sitting at 57°F which is pretty much normal for this time of year, nothing wild there. Monday morning the 24th is a bit of a non-starter with tiny 2ft SSW swell and a moderate cross-off wind, but it’s clean. The real highlight in the opening days is actually Monday afternoon – the wind drops to glassy, and while the swell is still small, that glassy surface will make it feel way better than it should.
Things start to get interesting on Tuesday the 25th. The morning shows a solid groundswell pulse from the WSW of 2ft with a long 15-second period, and a moderate cross-off breeze. That’s clean, consistent, and has some proper push for a point break. This is a standout for the first week, with a combined energy of 292 (moderate). The afternoon goes a bit windier, but the morning is the pick.
Wednesday the 26th is a big one. By the afternoon, we’re looking at 6ft of WSW groundswell at 12 seconds, with a light SE breeze and a combined energy of 836 (moderate to strong). The conditions are clean, and this is a very good day for experienced surfers. The morning is also decent with 4ft and a combined energy of 541.
Thursday the 27th gets big. We’re talking 12ft of WSW swell at 14 seconds, but the wind is cross-onshore and it’s choppy. That’s expert-only territory, and the combined energy is a massive 4783 (very strong). It’s a powerful, messy beast. Not one for the average punter.
The real standout of the whole outlook is Saturday the 29th. The morning has a 6ft WSW groundswell, glassy conditions, and a combined energy of 1016 (strong). This is the best surf of the week – clean, solid, and with that long-period power. The afternoon gets a bit onshore, but the morning session is a gift.
From Sunday the 30th, things drop off and get messy with onshore winds and choppy conditions until the end of the first week. The second week starts poorly with strong onshore winds and poor surf from Monday the 31st right through to Wednesday the 4th of September. There’s a brief glimmer on Friday the 4th of September afternoon – 7ft of WSW groundswell, glassy, and a combined energy of 1668 (strong) – that’s a solid session for experienced surfers. Then another good one on Monday the 7th of September morning with 6ft, glassy, and a combined energy of 1053 (strong). Finally, Tuesday the 8th of September morning is a standout for the second week: 8ft SW groundswell, glassy, and a combined energy of 2200 (strong). That’s expert territory, but pristine.
Overall, the best on offer is Saturday the 29th of August morning for the primo glassy conditions and solid swell, and the real dark horse is Tuesday the 8th of September morning for the big, clean groundswell.
Rusty out.

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