The Lowdown
Alright folks, Rusty here. Let’s get into it.
The surfing over the next couple of weeks at Algarrobo is a mixed bag – a few decent windows, but plenty of grovelly or wind-affected days to sift through. The water is sitting at 57°F and that’s a touch warmer than normal for this time of year, so you won’t need the thickest rubber.
We kick off Monday afternoon, 7th September, with a light west wind and 4ft of SW swell. The energy is moderate (716), but the word on the beach is marginal – tide might be a factor. Tuesday looks similar, maybe a little smaller, and the wind swings cross-shore or cross-on, so don’t expect any magic.
Wednesday morning, 9th September, is one of the better calls. The swell drops to 3ft from the SW, but with a light SE cross-offshore breeze, it cleans right up. The energy is moderate (380) and the wave comment says “good surf conditions.” That’s your pick for the first week – small but clean, perfect for a log or a fish.
The real standout comes Sunday morning, 13th September. The wind goes glassy from the ENE, the swell is 5ft from the SW, and the energy is solid (535). The forecast calls for “very good surf conditions.” This is the one to circle. The swell direction is directly from the SW, which is the optimum for this reef/pier break. The period is 9 seconds, average, but with that glassy surface, it’ll be fun and clean. Get out there early; crowds are possible at this spot.
After that, the second week gets windier and more inconsistent. There’s a blip on Saturday morning, 19th September, with 4ft from the WSW and a light cross-shore wind – energy is moderate (495) – but it’s a marginal call. The 20th Sunday afternoon sees a 7ft swell from the WSW, but a fresh 19 mph cross-onshore kills it. Too much wind for a paddle; that one might be more interesting for the kite crew.
The long-range stuff around Monday 21st and Tuesday 22nd drops off in quality. The swell sticks around 5-6ft, but winds are cross or cross-on, and the energy is moderate. Nothing to get excited about.
Overall, if you’ve got a window, make it Sunday morning, 13th September – that’s the pick of the 16 days.
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.
