The Lowdown
Alright folks, Rusty here. Let’s take a good look at what’s coming our way for Algarrobo over the next couple of weeks.
We’ve got a solid run of surf on the cards, but it’s a mixed bag of conditions. The standout period is definitely the first few days, with a powerful and clean window that’s got my heart thumping a bit faster. The water temp is sittin' around 56°, which is about average for this time of year, so the wetsuit is your friend.
Monday 27th July kicks things off with a bang. Algarrobo is pumpin’ with a 7ft swell from the W, packing a strong 14-second period. The wave energy is massive – a reading of 2046 – and we’ve got a light cross-offshore breeze from the N. This is serious, powerful surf for experienced surfers only. The sets will be long and clean, and the shape will be excellent on that reef.
Into Tuesday 28th July, the swell drops slightly but stays solid. The morning shows a 8ft W swell at 12 seconds, with a 1548 energy reading. The wind is cross-shore from the NNW at 10 km/h, making it a bit tricky. The afternoon then drops to 7ft, still with a cross-shore, so it’s a bit messy. It’s surfable, but not as clean as Monday.
Wednesday 29th July is where things get interesting. The morning glass off is a dream. The swell drops to 4ft from the W at 12 seconds, but with zero wind, it’s absolutely glassy. The energy is moderate at 531, but the quality for a mid-length or longboard will be top-notch. The afternoon sees a light cross-shore, but the morning is the session to chase.
Saturday 1st August is another one to circle. The morning brings a 6ft SW swell at 12 seconds, with a 1029 energy reading, and it’s glassy again with the SE wind dropping to zero. That’s clean, powerful, and perfect for the reef. This is a real high point for intermediate to experienced surfers.
Sunday 2nd August afternoon looks promising too. The swell builds back to 7ft from the W at 10 seconds, but the wind is a light cross-off from the N at 10 km/h. The energy is moderate at 747, and the clean conditions mean those waves will be peeling nicely.
Monday 3rd August continues the run. The morning is another 6ft WSW swell with a light cross-off, and the afternoon goes glassy with a 5ft W swell. Two solid days of clean, rideable surf.
Now, the second week gets a bit more complicated. Thursday 6th August sees a big spike in energy, with a 10ft WSW swell at 14 seconds and a 2979 energy reading, but the wind is cross-on from the SSE, creating a bit of chop. This is big, powerful, and only for experts. The same goes for Friday 7th August and Saturday 8th August, where we see 10ft+ SW swells with strong cross-onshore winds, making for some real heavy, lumpy conditions. This is more of a challenge than a pleasure.
The week closes out with a return to cleaner conditions. Sunday 9th August is a standout for the second week. The morning brings a 7ft SW swell at 13 seconds with a light cross-off from the N, and the energy is a solid 1483. It’s clean and powerful. The afternoon holds the same quality. Monday 10th August is cleaner but the swell drops, and Tuesday 11th August is a bit messy again.
So, for the best on offer, I’d be all over the morning of Wednesday 29th July for the glassy, clean 4ft waves, and the Saturday 1st August morning session for the glassy, 6ft SW swell. The Monday 27th July afternoon is the one for the adrenaline junkies, but it’s expert territory. The long-range window on Sunday 9th August is a promising but less certain call for some solid, clean surf.
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.
Algarrobo is 21 km (13 miles) from the city of Valparaiso. If you plan a holiday in Santiago, look for hotels and other accommodation in Valparaiso. Valparaiso has rooms for a wide range of budgets as well as car hire and transport links.
