The Lowdown

Alright, surfers, Rusty here. Let's cut through the noise and look at what Algarrobo has on the table for the next couple of weeks. It’s gonna be a bit of a mixed bag, so let’s break it down day by day.

First off, don't get too excited about the immediate forecast. We're looking at a few days of weak, short-period swell and cross-onshore winds, which is going to make things pretty chopped out and messy. The water is hanging in there at 58°, which is a touch warmer than normal for this time of year, so that's one small win.

The first real chance of a wave comes on Saturday the 12th. The swell bumps up to 6ft, but it's a short, fat 8-second period. The morning has a light cross-shore, so there could be a few semi-rideable ones out at Algarrobo, but it's going to be a bit of a battle. The energy is moderate at 485, but this is more of a junky, reform-type wave than anything clean. The afternoon gets worse as the wind swings onshore. This is more of a look-and-see session.

Now, hold on to your boards, because Sunday the 13th is where things start to turn on. The morning is an absolute gem. We have light, offshore SE winds, making it glassy, and that long-period WSW swell arrives with a solid 18-second period. It's a touch smaller at 2ft, but the energy jumps up to a strong 581. This is a classic case of quality over quantity. The glassy conditions will make Algarrobo feel like a different spot. This is a stand-out. It's a reef/pier setup, and with that long period, it should hold up nicely.

The good spell continues into Monday the 14th. The morning is clean again with a light cross-offshore SE breeze. The swell has built to 4ft and the period is still a solid 15 seconds. The energy is right up there at 954, which is strong. This is the bigger, more powerful version of Sunday's wave. This is your other standout. Make the most of the morning though, because the wind swings to a moderate cross-onshore in the afternoon and chops it all up.

After that early-week tease, things get a bit inconsistent. The swell drops back to the 3ft range with shorter periods, and we get a few days of cross-onshore breezes. Waves are going to be tough to find from the 15th through the 17th. There’s still some energy around, but the quality is just not there.

Things get interesting again but for the wrong reason on the 18th and 19th. We see a jump in swell size, blowing up to 6ft by the 19th. But this isn't a clean groundswell. The period is short, and we are getting hammered with moderate to fresh cross-onshore winds. It's going to be big, messy, and lumpy. It's going to be more of a washing machine than a wave machine. The energy is strong at 824, but this looks like a day to watch, not to paddle out. If it's blowing like that, the setup might honestly be more interesting for the kite crew than us surfers.

The last week of the forecast, from the 20th to the 24th, is pretty ordinary. The swell stays in the 3ft to 5ft range and the winds just don't cooperate. We get stuck in a pattern of cross-onshore and choppy conditions. There’s some moderate energy in the water on the 21st, but the short period and wind will keep it poor.

So, here’s the bottom line. It's a tough stretch overall, but there are two standouts. The glassy, clean conditions of Sunday morning the 13th are not to be missed, and Monday morning the 14th offers a more powerful, clean option. If you can get out on either of those mornings, do it. The rest of the window, you might be better off doing some maintenance on your board.

Keep it salty,

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.
