The Lowdown
Alright, this is Rusty. Let's have a look at what's on the table for Algarrobo.
Right off the bat, I gotta be straight with you – this forecast is a bit of a grind to get through. The first few days are just plain ugly. We’ve got a persistent cross-onshore wind messing things up, and the ocean is looking lumpy and choppy. For the first week, from Tuesday the 1st right through to the end of that week, it’s all "poor surf conditions" with a score of zero. It’s not gonna be worth paddling out unless you’re just desperate for a saltwater rinse. The water is sitting at 57°, which is about 2° warmer than average for this time of year, so it’s not freezing, but the wind is just ruining everything.
The first real glimmer of hope comes on Sunday the 6th. The wind finally swings around to the west-southwest and goes light, becoming onshore but very light – just a slight air, barely a breath. The swell is a solid 5ft to 5ft with a long 14 to 15 second period, coming from the southwest. The combined energy is strong (991-1077), so there’s some push. It’s rated as marginal, but with that clean wind, it's the best we’ve seen. It’s not a full-blown standout, but it’s the only window where you’ll get a halfway decent wave.
After that, we’re back into a long stretch of cross-onshore winds and poor conditions. The forecast doesn't really offer anything that I'd call a true standout. The swell pulses up again around Friday the 11th with a 7ft morning swell (SW, 12 seconds) and strong energy (1083), but again, the cross-onshore wind is just going to chop it up. For a reef and pier setup like Algarrobo, that constant cross-shore wind is a killer. The setup is better suited for a more forgiving wind.
So, to be honest, if you're looking for a clean, classic session, the week is pretty much a write-off. The only day I’d even consider getting wet is Sunday the 6th, early. That’s your best bet. Otherwise, it’s a waiting game. Forecasts change, but for now, it’s a tough stretch.
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.
