The Lowdown
Right out of the gate, the surf’s pretty flat. Weak WSW swell and the wind is all over it—cross and cross-onshore Monday and Tuesday. Water temp’s about normal for this time of year, nothing crazy. It’s a slow, frustrating start, so don’t bother paddling out yet.
Wednesday morning finally cleans up with a SE offshore breeze. Still small, around 3-4ft, but it’s glassy and the swell’s in the right direction. Thursday is a bit weaker, light cross-onshore, but still surfable.
Then we hit the first real window: Saturday the 19th. The wind goes totally calm—glassy—and the swell bumps to 4ft from the SW. The energy is the strongest we’ve seen so far. This is a fun, clean day. Watch for crowds, but if you get out early, it’ll be worth it.
Sunday gets a little bigger (4ft+) but the afternoon wind turns onshore and chops it up. Monday the 21st builds to over 5ft but it’s messy and cross-onshore—poor quality. Tuesday is a write-off.
Now, the big one: Friday the 25th. This is the best surf of the whole stretch. Clean 4-5ft W swell, light offshore NE wind, and solid energy. The conditions are calling it “very good.” It’s not huge, but it’s clean and lined up. The period is a bit short, so it might not be super powerful, but the offshore wind will make it smooth. This is the day to call in sick.
Saturday the 26th gets bigger—up to 6ft—but the afternoon turns ugly with strong cross-onshore winds and heaps of energy. That’s a lot of power, but it’ll be a washing machine. Sunday settles down, but it’s still average. By Monday and Tuesday the 28th-29th, it’s tiny—1-2ft and flat. Not worth it.
So, two standout days: Saturday the 19th for clean, glassy conditions, and Friday the 25th for the best combo of size and wind. The rest is a heap of waiting for the ocean to sort itself out.
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.
