The Lowdown
Alright, Rusty here. Let’s get into what’s cooking over the next couple of weeks.
We’re looking at Huascar, a consistent advanced point break that lights up with swell from the NW. Right off the bat, there’s not much happening just now, but don’t walk away yet – the real action starts to build as we move through the week. The water temp is about average for this time of year, nothing weird going on.
Sunday the 16th is a bit of a slow starter. The morning has a weak 3ft swell from the WSW with moderate wave energy (431) and a light onshore breeze – not great. But the afternoon flips completely. The wind goes dead glassy, almost calm, with a 3ft groundswell from the SW at a very long 15 seconds. The wave energy is still decent (397). That glassy window will make for some clean, lined-up waves, even if the size is small. This is the pick of the first few days.
Monday the 17th and Tuesday the 18th are a write-off. The wind swings cross-onshore, the swell stays small and the energy drops off. The sea gets lumpy and messy. Nothing worth paddling out for.
We get a slight flicker on Wednesday the 19th morning – a 4ft SW swell with moderate energy (522) and light cross-onshore wind. It’s a maybe, but the wind picks up hard in the afternoon with a 30 km/h cross-shore, so that session is blown out.
Thursday the 20th through Saturday the 22nd are all marginal. The swell is hanging around 3ft to 4ft, mostly from the SW, but the wind is cross or cross-onshore, not ideal. Energy is moderate – around 300 to 560. You might get a few, but you’ll be fighting the chop.
Now, Friday the 21st is a little standout. Both morning and afternoon go glassy. The morning has a 2ft SW groundswell (12 sec period) with very low energy (320), but those clean, smooth conditions mean every wave you get will be worth it. The afternoon bumps up to 4ft with a shorter 9 second period, but still glassy with 288 energy. If you’re after a fun, cruisy session without the wind hassle, that’s your window.
Then things drop right off. Sunday 23rd through Tuesday 26th of August are pathetic. Swell drops to 0.3ft – 1ft, energy plummets into the double digits, and the wind is all over the show. That’s nearly a full week of flatness. Don’t bother.
But then we get a spark again. Thursday the 27th morning is glassy with a 2ft SW groundswell carrying a long 17 second period. That’s a proper groundswell pulse. Energy is strong at 469. The sets will be clean and well-shaped, but the period is so long it might break a little too straight for this point. Still, in glassy conditions, it’ll be a treat. The afternoon stays okay, but a light cross-shore creeps in.
Friday the 28th is mixed – light onshore in the morning, cross-shore in the afternoon. The swell is around 2ft to 3ft, so not big, but there’s enough energy (464 to 519) to make it worthwhile if the tide is right.
Now, hold onto your board – the weekend of the 29th and 30th of August brings the biggest swell of the entire forecast. Saturday the 29th sees 6ft to 6ft SW swell (13 sec period) with strong wave energy (1006 to 1089). That’s serious power. The wind is cross-shore at 15-20 km/h, so it’ll be a bit lumpy, but for advanced surfers this is the main event. At over 5ft, it’s too big for beginners. Sunday the 30th stays big – 5ft – but the wind goes cross-onshore, making it choppy and messy. The energy is still high (831 to 710), but the quality drops.
Monday the 31st is still pumping 6ft but only from a 9 second period, which means less organised, more chop with a cross-shore wind. A lot of energy (575) but not the best shape.
Overall, the best on offer is Saturday the 29th for the bigger, powerful SW swell – the biggest of the period by far – but only for experienced surfers. For clean, classic conditions, Friday the 21st with glassy winds is the hidden gem.
Rusty.

Information about the Huascar Surf forecast
The above surf forecast table for Huascar provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Huascar can be found by selecting the local surf guide option on the grey menu. Our Huascar 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 (Huascar) 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 Huascar 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.
