The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, we’ve got a solid, sizey pulse hitting Algarrobo. The water is sitting at 56.1°, which is only 0.6° above normal for this time of year, so pretty much what you’d expect.
The standout window is clear: Thursday morning, August 27 through to Friday afternoon, August 28. Thursday morning kicks off with a clean 11.5ft swell from the WSW, carrying serious grunt – the combined energy is a whopping 4960, which is well into very strong territory. The period is a long 14 seconds, so this is proper groundswell, with real push and long lulls between sets. The wind is light from the SW, right on it, but it’s not strong enough to ruin things. Friday, August 28, is actually where the magic happens: the swell drops to a still-chunky 8.2ft, still from the WSW and 13 seconds of period, and the wind goes glassy – dead calm. That is as good as it gets for clean, powerful waves at this break. Friday afternoon holds similar conditions with 7.9ft and glassy calm. For the experienced surfer, this is the session to chase.
Saturday, August 29, the quality starts to slide as a cross-on breeze sets in from the SSW, making things a bit lumpy. The swell drops to 6.2ft, and the energy has backed off to moderate levels (1016). It’s still surfable, but not the pristine stuff we saw on Friday.
From Sunday, August 30, onwards, things get messy. The wind stays cross-on, and while the swell hangs around 5.2ft to 4.6ft through Monday, it’s choppy and blown out. By Tuesday, September 1, the wind picks up to 12-16 mph from the SSW, and it’s just poor conditions all around. This poor run stretches out for days. There’s a small window of marginal surf on Thursday, September 3, with a 4.6ft WSW swell and a very long 14-second period, but it’s still cross-on and choppy. Not worth paddling out for.
The second week continues the struggle. There’s a notable bump on Saturday, September 6, with 6.2ft from the WSW and combined energy of 1152 (moderate), but again the cross-on wind ruins the surface. From there, it’s a long slog of poor to marginal conditions right through to Friday, September 11, with messy winds and fading swell.
Honestly, dial in on Friday, August 28. That morning with the glassy conditions and a solid 8.2ft WSW swell is your one true standout.

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.
