The Lowdown
G’day, Rusty here.
Alright, let’s have a look at what’s in store for Algarrobo. Bit of a mixed bag over the next couple of weeks, but there’s a short window that’s worth paddling out for.
The pattern starts with some leftover energy on Sunday the 30th of August, but those winds are going to mess it up. We’ve got a 5ft WSW swell with moderate energy (627) and a decent 11-second period, but a cross-shore breeze is going to make it rough. Skip it. Monday the 31st of August morning is where it gets interesting. The wind drops to nothing – glassy conditions – and we’ve got a 4ft WSW swell, still packing moderate energy (527) and a nice 12-second period. That’s your standout session for the near term. It’s a reef and pier setup, very consistent, so you know it’ll be working. The water temp is sitting at 57°, which is about average for this time of year. Keep in mind, the optimum swell direction is from the SW and this is coming from the WSW, so it’s a touch off, but on a glassy morning, that’s a trade-off you take.
After Monday morning, the quality drops off fast. From Tuesday the 1st of September right through to the 13th of September, it’s mostly a write-off. The winds turn cross-onshore and stay that way for over a week, with speeds often 18 – 19 mph, just chopping everything up. Swell sizes bounce around but the conditions never line up. There are a couple of moments where the swell gets bigger – like the 4th of September with a 6ft WSW and strong energy (1176) – but the wind is just too strong. That setup looks more interesting for kite surfing than paddle surfing.
There is a small window on Sunday the 13th of September morning. A drop to glassy conditions again with a 3ft SW swell, but the energy is weak (233) and the period is short (10 seconds). It’s just not enough to get excited about after waiting that long. The deep run of poor conditions is a real bummer for the area, but keep an eye on the long-range, because forecasts can always shift.
Signing off, Rusty.

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.
