The Lowdown
Hey crew, Rusty here. Let’s talk about what’s coming up at Algarrobo over the next couple of weeks. This reef/pier setup is very consistent and exposed to SW swell, so we’ve got a fair bit of action on the cards. Right now, Friday afternoon, it’s a write‑off – stormy wind from the north at 30 mph, small 2.6 ft SW swell with a 13‑second period, and the water is sitting at 54°, a bit colder than the average for this time of year. Not worth paddling out.
The first glimmer of hope comes Saturday morning, but it’s still marginal. A 5.2 ft WNW swell with 9‑second period picks up, but the cross‑off wind keeps things messy. By Saturday afternoon it’s similar. Sunday morning is where it starts to get interesting – glassy conditions with a light SSE breeze, 5.2 ft W swell at 11 seconds, moderate energy (755), and the forecast says “very good surf”. That’s your first real session. The afternoon turns cross‑on, so morning is the call.
Monday the 20th brings light winds and clean 3.3–3.6 ft W swell – good for a cruise, but nothing special. Tuesday the 21st gets blown out again with strong north winds. Then Wednesday the 22nd – this is a standout day. Wednesday morning we’ve got a solid 9.8 ft W swell from the west, period 12 seconds, and the combined energy is a hefty 2491. That’s expert territory – too big for beginners, but for experienced surfers it’s excellent. The wind is light cross‑off, so it’s clean. Wednesday afternoon still holds 8.2 ft, still excellent. If you’re skilled, don’t miss it.
Thursday the 23rd is glassy again – 5.9 ft WSW swell at 10 seconds, very good conditions. Friday the 24th is good but smaller, around 3.6 ft. Then we hit a bit of a lull over the weekend of the 25th–26th: long‑period 16‑second swells but only 2.0–2.6 ft, and the wind is cross‑shore or cross‑on, so surf is marginal at best. The energy is moderate (around 400–500) but the shape is poor.
Monday the 27th brings a return to quality – glassy morning with 5.6 ft W swell, 10‑second period, very good conditions. Tuesday the 28th is another standout: 7.2 ft W swell at 13 seconds, glassy, combined energy of 168

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.
