The Lowdown
G’day, Rusty here. Well, lookin’ at the 16-day window for Huascar, it’s a bit of a mixed bag, a real waiting game for any kind of quality. We’ve got a point break setup – Huascar – which is an advanced wave, consistent, exposed to the NW swell. It’s picky, though, and for the first week or so, the conditions are pretty ordinary.
Right off the bat, Monday the 17th of August through to Thursday the 20th is pretty much a write-off. We’ve got small swell, mostly around 3 ft to 5 ft from the SW, but the wind is a constant cross or cross-onshore. That’s just gonna leave it choppy and messy. The water is a standout, mind you – sitting at 64°, which is 4° warmer than normal for this time of year. That’s a solid anomaly, much warmer than usual.
Now, Friday the 21st of August is the real gem in this entire forecast. The morning kicks off with glassy conditions, zero wind, and a clean 3 ft SW groundswell with a period of 9 seconds. The combined swell energy is moderate (275). The afternoon’s glassy too. This is the window. For an advanced point break with that kind of clean, lined-up swell, it’s as good as it gets in this outlook. The swell’s not big, but the quality’s there.
After that, it falls apart again. Saturday the 22nd and Sunday the 23rd see the swell drop to 2 ft to 3 ft, and while there are some glassy moments, the waves are just too small and weak to get excited about. We then hit a proper dry spell from Monday the 24th of August all the way through to Thursday the 27th. A long gap of tiny, weak energy (values around 80 to 130) with cross-shore or cross-onshore winds. Nothing worth paddling for.
It starts to pick back up on Friday the 28th of August and into the weekend. The swell builds to 4 ft to 5 ft from the SW, with a very long period of 16 to 18 seconds. That’s proper groundswell energy, and the combined energy readings are strong (908 on Friday morning, 1031 Friday afternoon). But – and it’s a big but – the wind is still cross or cross-onshore. At an advanced point break, a long-period swell with cross-shore wind can be a bit of a handful, breaking a bit straight. It’s far from the clean glass we had on the 21st.
The last few days, from the 30th of August into the 1st of September, show a consistent 4 ft to 5 ft SW swell, but the wind stays cross-shore and bumps up to a moderate 9 to 15 mph. The energy is there (values in the 700s and 800s), but the quality is going to be average at best, with a cross-chop spoiling the face.
So, if you’re a keen surfer at Huascar, you’ve really only got one true standout: Friday the 21st of August. The glassy conditions with that clean SW 3 ft swell will be a treat. The rest of the run is either too small, too windy, or too messy to get excited about. The late August pulse has the size and energy for advanced surfers, but the wind’s gonna make it a fight. Not much here for the weekend warrior, just a waiting game for that one clean morning.
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.
